Introduction
QRS is pleased that you have chosen the QRS Pianomation™ MIDI Retrofit Kit, the superb new retrofit kit for automating acoustic pianos. This product brings a level of excellence in reproducing live performances on the piano. It is made possible by many remarkable technical innovations. However, in spite of its high level of sophistication, this retrofit kit is easy to install and service.
This manual provides procedures for installing, aligning and troubleshooting the QRS Pianomation MIDI Retrofit Kit. The kit is an electronic solenoid-actuated playing mechanism requiring a power source of 115 volts or 230 volts, at a frequency of either 50 Hz or 60 Hz. The QRS Pianomation Retrofit Kit has been designed to accommodate almost all makes and models of pianos. This manual directs the technician through the steps of installing the kit in a grand and upright piano.
The manual is divided into four parts. Part I introduces the technician to the kit and its component parts and provides a list of the tools needed to effect an installation. Part II details the procedure for installing the kit and electronic alignment of the system. Part III provides procedures for the installation of the optional equipment & helpful hint guide. Part IV provides pertinent information about Pianomation accessories.
The QRS Pianomation MIDI Retrofit Kit has been designed to be easily installed and adjusted. However, there are some special points which will make for a successful installation.
First, all piano keys have a tendency to react differently. The key solenoids provide three adjustments: one to remove lost motion between the key tail and the pusher tip, the second adjusts the amount of plunger throw to match that of the keytail lift. The other is you have the capability to adjust the force for each individual key solenoid and corresponding piano.
Second, although the kit has been provided with enough solenoids to play 80 notes, the instrument has been designed to support the entire 88-note range of modern pianos. The additional solenoids required may be purchased separately if an 88-note installation is desired.
Third, the instrument uses relatively low voltages supplied by an isolation transformer. Low voltages eliminate the danger of electrical shock to the installer (Below UL limit of 41V).
Fourth, the electronics are fully shielded to prevent electromagnetic interference.
Fifth, the kit has been designed to operate with most high-quality commercially available CD players with audio outputs. MIDI generating equipment will also operate Pianomation.
Sixth, Pianomation MIDI can handle data in both digital and analog forms. Analog control opens up a whole new world of different musical presentations and electronic interfacing. PART I. Getting Acquainted
Parts List and Nomenclatures
Before beginning the installation, take time to read Chapter 1, “Make Certain the Kit Fits,” to ensure that the piano will indeed accept the kit. Also, familiarize yourself with the parts in the kit before proceeding. It will, for example, prove a major inconvenience if you discover at the end of the procedure that you have installed the solenoid rail oriented backward. Let the instructions guide you.
It must be noted at the outset that you will require materials not provided with the kit to complete the installation. The present chapter will introduce you to the parts provided. Take the time to familiarize yourself with them before beginning work.
The solenoid rail places a key solenoid under each key to be played. As an assembly, it consists of two parallel aluminum rails with 40 cross-diagonal braces with holes for mounting the key solenoids. The key solenoids are accessible from the bottom for ease of alignment and service.
Each key solenoid consists of a tubular solenoid coil with a threaded collar, a plated plunger assembly, a bottom threaded plastic retainer cap with internal foam cushion, and a rubber plunger tip. Each cross diagonal brace can hold two key solenoids. Two end braces hold three solenoids.
The assembled solenoid rail clamps 37 cross-diagonal braces and two end braces which hold three solenoids. Eight rail mounting brackets attach the completed assembly to the bottom of the piano's keybed.
The processor chassis contains the printed circuit board which decodes the information from the MIDI signal source and then sends it to each of the system's five 16-note driver boards as well as the pedal driver circuit.
Two different power supply's exist. The first is a 115V model (70210) and the second is a 230V model (70211) with alternating current at a frequency of either 50 or 60 Hz and converts it to the various voltages necessary to operate the system. An external fuse (MTH 7, 3AG 7 Amp Fast-blo fuse (70219)) protects the entire system from voltage surges. An internal fuse (5mm 250 volt .5amp Slo- Blo fuse) is located on this unit's internal printed circuit board.
Six different types of cables are supplied to interconnect the various components of the kit. All cable connections are keyed, so that insertion into a wrong port is impossible.
A standard 3-prong grounded cord (70214) brings line voltage (115V) to the power supply socket.
The driverboard power cable supplies power to the 5 key solenoid driver boards. This 108" cable plugs into the "Rail Power" socket on the power supply . The second, third, fourth, fifth and sixth 4-position plugs insert onto the five 16-note driver boards (70120). PART I. Getting Acquainted
Parts List and Nomenclatures
The driver board logic cable (70319) has a DB37 ribbon cable that connects the processor board to the five 16-note driver boards. This is a 108" long logic cable.
The processor/power supply ribbon cable is a 24" long 16-position ribbon cable, and connects the processor board to the power supply.
The user control box cable (70329) is 72" long and has a DB15 computer connector to plug into the processor board and DB15 computer connector that connects to the user control box.
The installer alignment box has a 100" cable which plugs into the processor chassis.
The resistor box (70258) verifies that no solenoids are shorted, before turning on the piano. This prevents unnecessary damage to the driver boards.
The Solenoid Short Tester (70259) tests for ground shorts in all solenoids.
This kit also includes a 6 ft. shielded cable with RCA male phono plugs (70131) for connecting a CD player to the kit.
The user control box has standard MIDI plugs for MIDI IN, MIDI OUT, and MIDI THRU. The various MIDI cables required to access these functions are not included with this kit.
The standard Pianomation kit (71200, 71202) comes with no pedal solenoid (70130) and runs in magic pedal mode. The key solenoids control the sustain events by extending note durations to the corresponding pedal OFF event. A Sustain Pedal Solenoid (70130) is available as an option to control the sustain function by lifting the damper tray. It can be connected to the power supply by a 4 position plug.
The Pianomation kit (70000 & 70002) is the same the 71200. However it comes supplied with a pedal solenoid and user box with remote control.
The Pianomation kit (51200) comes with no pedal solenoid (70130) and runs in magic pedal mode. The key solenoids control the sustain events by extending note durations to the corresponding pedal OFF event. A Sustain Pedal Solenoid (70130) is available as an option to control the sustain function by lifting the damper tray. It can be connected to the power supply by a 4 position plug. This system comes with a CD User box.
The Pianomation kit (50000 & 50002) is the same the 51200. However it comes supplied with a pedal solenoid (70130) and CD user box with remote control. PART I. Getting Acquainted

Make Certain the Kit Fits
This chapter allows the installer to determine whether the components will fit into a particular piano and how to accomplish the installation most easily.
All kits play 80 notes, excluding the highest and lowest 4 keys of the standard piano keyboard. The following questions should be asked before beginning an installation:
1. Is it a grand or upright piano?
2. Is the keybed made of wood or a wood-veneered laminate?
3. Does the piano have a range of 88 notes, extending from low A to high C?
4. Is the key frame made of wood?
5. Is the piano well-regulated and in good mechanical condition?---that is, all of the keys play without binding or locking, the key heights are uniform with the proper key dip, and all of the dampers function and lift evenly with the sustain pedal.
6. Does the piano have sufficient space beneath the soundboard or inside an upright to mount the pedal solenoid & power supply (5.25" x 5.25" x 12.5")?
7. Can the back of the key frame be cut away 1 1/8"? PART II. Installation and Alignment Procedures
Modify the Piano Action
The piano action will probably require modification to accommodate the Note Rail Assembly (70050). The key tails must protrude over the back of the action frame, so the rear of the key frame must be cut away. The underside of the key tails must be felted.
Tools needed for this chapter: pencil, paper, wood chisel, straightedge, jig saw, palm sander & sand paper, utility knife, wood glue and an assortment of screwdrivers.
At this point in the installation, the piano is on its legs, the fall board, keyslip, and cheek blocks have been removed, and the lyre is still in place. The piano has been measured to verify that the Note Rail Assembly will fit.
Measure the distance the action shifts when the left (una corda) pedal is pressed. (If a hammer lift rail is installed, measure the distance the hammers lift for a given movement of the soft pedal lyre lift rod.) Measure the distance the soft shift (una corda) pedal lift rod travels when the pedal is depressed. Write these measurements down for later trapwork installation.
IMPORTANT: Before removing the hammer action from the key frame action you must first measure the distance from the bottom of the key frame action to the bottom of the piano key. Next, depress the key by pushing on the ivory, and measure once again, from the bottom of the key frame action to the bottom of the key. Write these measurements down for later use.
Remove the entire grand or upright piano action from the piano and place it on a clean, level workbench. Do not depress the keys while sliding the action in or out of the piano, or broken hammers will result.
Examine the relationships of the key tails to the rear edge of the keyframe. Each key tail must have at least 1-1/8" exposed beyond the rear edge of the key frame. If this is not the case, then the key frame must be modified. If modifications are required, follow these steps:
With a screwdriver remove the wooden key stop rail from the key frame.
With a screwdriver remove the hammer action from the keyframe, being certain to note any screw length differences in the 8 or 10 wood screws used to secure the action to the keyframe. It is always advisable to put the same screw into the same hole.
Verify that the keys are properly numbered before removing them. Remove all keys except key numbers 5, 84, and the break keys. With a pencil, mark 1-1/8" in from the ends of the key tails onto the keyframe. Allow an additional 1/4" at either end of each section. With a straightedge to guide you, connect the marks in each section. Removal of the back rail felt may be required before this step. (Figure 1)
The back rail felt rests beneath the key tails, and can be removed by using a sharp utility knife or in some cases a wood chisel. Place the removed backrail felt to the side for future use when relocating and regluing in its new position.
The key frame must now be cut. Remove all keys. With a jig saw, follow the pencil line and cut away the frame in each section between the breaks.
With the palm sander, clean up all the rough edges. PART II. Installation and Alignment Procedures

Modify the Piano Action (Cont.)
The action is now ready to be used to locate the positions of the slots through the piano's keybed.
Place the keyframe into the grand piano case and secure it with the right and left cheek blocks. With a short, sharp pencil, reach into the keyboard compartment and mark the notched rear most limits of the keyframe, including the right and left extremes of each notch (Figure 2). These lines will be used to identify the exact locations of the keybed slots on the underside of the keybed, so be certain to make well-defined pencil lines.
Remove the keyframe and reglue the keytail felt flush with the back of the keyframe. Measuring the key dip before and after repositioning the felt is recommended. If it is the same, less regulation will be required. If it has changed, simply shim the back edge with a thin piece of cardboard to maintain the original key dip.
With the utility knife, cut the 1 1/16" wide self adhesive keytail felt strip (70084) into pads wide enough to cover the bottoms of the key tails. Press the felt pad firmly onto each key tail such that it is flush with the edge of the keys, as well as the end of the key.
Note: This is a good time to install the optional 88 note record strip (70014). See section on record strip installation.
Place all of the keys back on the key frame. The keytail felt should hang over the end of the key frame, so that no contact is make with the backrail felt.
Re-install the hammer action on the key frame, using the same 8-10 screws you removed earlier.
At this point, the grand action modifications are complete.
NOTE: It is imperative that the piano action be regulated to manufacturers specifications.

Figure 2 PART II. Installation and Alignment Procedures
Regulation of Grand Piano Actions
This discussion is not intended to be a complete course on grand action regulation, but rather may prove helpful in restoring the action to proper performance. Proper cleaning and lubricating, alignment of action parts, and key easing are all very important steps in the regulation procedure. The following procedure assumes that this preliminary work has been checked and performed as necessary.
3.01 Before removing the action from the action cavity, evaluate action regulation. If the action is not well regulated, proper performance of the system cannot be expected.
3.02 During the installation process of the Pianomation Reproducing System, it is quite possible that action regulation will be directly affected. A portion of the action frame back rail and back rail cloth will be removed so that the note solenoid plungers can contact the key tails. This operation may cause the key tails to be lower than their original position. The result of lower key tails is an increase in both key height, and hammer strike distance. Restoring the strike distance to specifications by turning out the capstan screws is not the proper remedy.
Are the keys level?
Do the hammers let off 1/8 in the bass, tapering to 1/16 in the high treble?
Is the drop 1/16 below the point of let-off?
Is the hammer line straight?
Are the hammer shanks approximately one shank thickness above the hammer rest rail?
Is there adequate after-touch?
3.03 With the action on a flat, clean workbench, measure and record the following:
Natural key height at bass and treble ends.
Sharp height above naturals.
Key dip; both naturals and sharps.
The height of the first and last hammers in each section of the action. PART II. Installation and Alignment Procedures
Regulation of Grand Piano Actions (Cont.) 3.04 Replace the keys and action stack on the action frame. Refer to the regulation measurements recorded earlier to see if regulation has been affected by the modifications to the action frame. If key height, key level, or strike distance are different than previously recorded, steps must be taken to restore proper regulation.
3.05 To restore key height, replace the back rail cloth with one of a thicker dimension. Remove the action stack and keys. After removing the old back rail cloth, be sure that all traces of glue have been removed from the back rail. Replace a few of the end keys and try various thickness of back rail cloth, without glue, to ball park the correct key height. Light finger pressure on the capstan screw will approximate the force that is normally on the capstan. Set key height with the back rail cloth at, or slightly below the desired key height.
When you are satisfied that you have the best choice of back rail cloth, glue the material to the back rail, leaving the rear edge unglued. Name board felt is available in a few different thicknesses, and can be used for fine adjustments when glued under the back rail cloth.
Although key height can be reestablished quite accurately using the above procedure, some key leveling is to be expected when replacing back rail cloth.
3.06 Remember that subsequent action regulation adjustments will affect those already performed. To prepare the action for fine regulation, do the following quickly:
Check or set repetition lever height so it is slightly higher than the jack. During your final regulation, trip the jack tender with your finger and release it slowly. If regulated properly, you will be able to feel the jack brushing the knuckle as it is released. The jack must return completely under the knuckle.
Set strike distance to 1 3/4. Be sure that hammer shanks are above the rest rail.
Check or set jack position so that the back edge of the jack is aligned with the back edge of the knuckle core.
Set let-off 1/8 from string in the bass, tapering to 1/16 in the high treble. Make sure that you have some drop after escapement.
Set drop to 1/16 below let-off.
3.07 With the above preliminary steps completed, level keys as necessary to their final specification. Note that with key height at the same specification as it was before action frame modification, key dip should be correct (assuming that the dip was correct prior to the installation procedure). Also, damper lift timing is reestablished. PART II. Installation and Alignment Procedures
Regulation of Grand Piano Actions (Cont.)
3.08 Check or set repetition spring. The spring should carry the hammer upward with a steady motion, without kicking.
3.09 With the preliminary action regulation done, you are ready to establish the strike distance and key dip measurements that will result in proper after-touch. Since the key height/key dip relationship has been reestablished, consider varying only the strike distance to get the proper after-touch. If you are working on an older instrument, consider varying both strike distance and dip to arrive at an acceptable compromise.
Select sample keys with which to work. I usually use the first and last two keys in each section.
Depress your first sample key very slowly, stopping its movement just after let off. Look to see if there is additional key travel left. If there is no additional key travel after the let off point, there is no after- touch. Key dip will have to be increased, or strike distance will have to be decreased. If there is too much additional key travel after the let off point, the hammer may block the strings when the key is played fully into its dip. Key dip will have to be decreased, or strike distance will have to be increased. Be sure that the sharps have the same after touch as the naturals. As a second check, see that with the key fully depressed, there is still some travel left at the jack tender.
When you have the key dip/strike distance established on your samples, set your key dip to your established specification uniformly throughout the action. You are now ready for the final regulation.
3.10 Using your new strike distance measurements, carefully repeat the above outlined steps for the final time.

Cut the Keybed Slots
A separate slot must be cut for each section of the piano action. This is required to ensure keybed integrity and stability. This chapter details the procedure for marking the position of the slots and then cutting them.
Tools needed for this chapter include a circular saw (sabre saw with a sufficiently long blade/ router may be used), a power drill with a sharp 1-3/4" Forstner bit (or wood boring bit), various screwdrivers, a frame square, a pencil, a tape measure, and matching paint.
At this point the piano is on its legs, the action is outside of the piano case and has been modified to allow the key tails to protrude over the rear of the key frame by 1-1/8". Felts are attached to the undersides of each key tail, and the original trapwork is still in place.
Next, have an assistant press the sustain pedal. While he depresses it, measure the distance the pedal lyre lift rod moves and write it down. Likewise, measure the distance the damper lift rail rises when the pedal is pressed. This measurement can be taken from inside the case. Next, mark the exact location of the upward extension of the pedal lyre's vertical rods onto the keybed bottom. Set these measurements aside for later trapwork installation.
Repeat the above step with the sostenuto pedal (if it exists).
There may be two or more action stop blocks ("dags") inside the case. These blocks stop the insertion of the grand piano keyboard at the proper location and prevent it from lifting up off the keybed. In the event that these interfere with the slot to be cut, remove by force applied by a sharp chisel and hammer.
Remove the lyre from the piano.
Turn the piano on its flat or bass side and secure it. Make a visible pencil mark outlining the bass and the treble legs. Next, remove each leg marking them accordingly (bass, treble, tail) and place in a safe area to prevent damage.
Use a pencil and mark the lyre rod strike points (where the lyre rods hit the original trap work) on the bottom of the keybed. Remove all trapwork, and other parts that may interfere with the keybed modifications from the underside of the piano.
Using a tape measure, record the distance from the front of the piano case to the marks you previously made inside the case. Do this on both the bass and treble end. Call this the depth measurement.
Transfer the slot marks made on the inside of the piano case to the underside of the keybed. PART II. Installation and Alignment Procedures
Cut the Keybed Slots (Cont.)
Taking into account any variations in the contour of the front of the piano and using the frame square aligned with the mark just made on the front underside of the keybed, measure and mark the depth measurement on the underside of the keybed. Next, measure 1/8" toward the front of the piano scribing a straight line between the bass and treble notes. Then measure 1-3/4" toward the rear of the piano from the newly scribed line. Whenever possible we recommend keeping in the breaks.
Each slot should be 1-3/4" wide. The longitudinal center of each slot must correspond to the center line of the felt padded key tails, which is 1/2" in from the end of each key.
Verify the marks just made. Drill a small exploratory hole within each slot and compare the position of the slot with the marks made inside the case. Correct each slot position as required.
Using a 1-3/4" Forstner bit, drill holes centered at the ends of each slot.
Cut the lengths of each slot with a sabre saw, circular saw or router (being extremely careful with all power tools), connecting the end holes just made. Avoid cutting away the breaks between the slots.
Note: Extending the soft shift slot 1" toward the front of the piano may be required. Now would be a good time to do it.
Rasp or sand the slots smooth and square with the surface of the keybed. Bevel the top most slot edges with coarse sand paper. The slots can be sealed with paint or other sealant to retard drying of the wood.
At this point the slots have been positioned and cut. The optional pedal solenoid and trap work can now be installed.

Optional Sustain Pedal Solenoid Mounting (70130)
You can now turn your attention to the installation of the sustain pedal solenoid assembly. This procedure is not required when installing the Magic Pedal Kit #71200 & 51200.
Because there is a certain amount of variation in the architecture of grand pianos, you will probably have to custom-tailor the following directions to suit the mechanical dimensions of the particular instrument you are working on.
The key elements to focus on here include the sustain pedal lyre rod's upward projection onto the keybed immediately above it, the location of the large hole through which the original sustain pedal pitman dowel projected to reach its corresponding hole in the wooden or aluminum damper tray (which lifts all of the piano's dampers simultaneously), and the rearmost OUTSIDE vertical wall of the keyboard compartment, called "the belly rail." The proper installation of the sustain pedal solenoid assembly takes into account the dimensional relationships of these three elements.
In addition to providing for both the manual and automatic operation of the piano's dampers, you want to give the sustain pedal solenoid as much mechanical advantage as possible in order to minimize the the power required to activate it. Despite the excellent design of the sustain pedal solenoid assembly, its long term operation depends upon your skill in locating the various leverage-points which enable it to function both manually and automatically.
Optimally, the sustain pedal solenoid assembly will be mounted on the belly-rail immediately behind the sustain pitman dowel which formerly connected the old trapwork lever's far end to the damper tray in the keyboard compartment. This arrangement provides the shortest distance between the sustain pedal solenoid assembly's lever-arm and the load imposed by the damper tray through the pitman dowel. Where such a situation exists, you will use the four mounting holes to locate the four #10 x 1" (70080) panhead screws used to secure this assembly to the belly-rail.
Now, measure the distance from the center of the pedal solenoid's pusher tip to the exact center of the damper tray's pitman rod location. Sixty percent (60%) of this distance FROM THE PEDAL SOLENOID'S CENTER (that is, the lion's share of this distance) is the location of the fulcrum of the trapwork assembly's stright bar. The remaining 40% of this distance becomes the minor portion from the fulcrum to the pitman dowel.
Distance = ______Damper tray pitman rod location

Install the Soft Shift Trapwork (70222 & 70224)
The soft shift (una corda) pedal mechanism usually includes a long, cast-iron bellcrank lever whose short-arm protrudes through the keybed to engage a groove cut in the bottom of the keyframe somewhere beneath the treble section. The shift pedal in this configuration does not have to pass through the solenoid rail and, therefore, may often be left untouched. However, on some pianos you may have to move the soft shift toward the front of the piano to accommodate for the width of the rail. For the pianos that need modifications, brackets have been included in the kit (70222 & 70224) for easy readjustment. The brackets can be attached to the keybed with four #10 x 1" mounting screws (70080 ). The pedal must shift the action the same distance as before with the same pedal movement. Refer to the measurements taken when the trapwork was removed to verify that this behavior has been retained (See "Modify the piano action" section) PART II. Installation and Alignment Procedures
Install the Sustain Trapwork (70270) Unfortunately, there is no set procedure for modifying the trapwork on a grand piano. Different manufacturers connect the pedals to their respective action mechanisms following their own designs. Ultimately, it is up to the installer's ingenuity to make the trapwork behave as it originally did. There are some design generalizations which can be observed.
Because the damper lift rail is always further back in the piano case than the key tails, connecting the sustain pedal to the damper mechanism requires a linkage passed over the plane of the rail. Likewise, if a sostenuto pedal is present, it must be linked to the monkey by means of a lever mechanism passing over the plane of the rail. The low profile cable system (70850) may be installed.
Tools needed include a drill with screwdriver attachments, a hack saw, a metal file.
At this point in the installation, you have before you a raw canvas upon which you must now execute your scheme for re-linking the pedals to the piano mechanisms. Allowable clearances over the rail can now be directly measured. The diagram below shows the proper setup for the trapwork included with the system.

Install the Optional Sostenuto Trapwork (70850)
Sostenuto Installation
The Sostenuto lifter installs into the keybed slot BEFORE THE SOLENOID RAIL IS INSTALLED. Refer to the diagram for PULL or PUSH application.
1. Mount the lifter assembly into the keybed slot directly under the stirrup of 1 the sostenuto rod. The cable stud should swing 1/8 to 1/4 inch below the keybed.
2. Determine cable length by holding the pedal actuator at the lyre position. To 2 ensure smooth operation and pedal response, MAINTAIN A MINIMUM BEND RADIUS OF 3 INCHES. The conduit end should be 2-3 inches back from the edge of the keybed slot so the tension adjustment will be accessible after the covers are in place. Please note that the conduit connector screws onto the conduit. Be sure to pull the cable out before cutting the conduit to length.
3. After replacing the cable and conduit, Thread the cable through the bottom hole 3 in the push/pull assembly. Wrap the cable around the fastening nut, check that the sleeve position will enable smooth movement through its full range. Tighten the cable to the bracket with a phillips screwdriver and a wrench. PART II. Installation and Alignment Procedures

4. The sostenuto monkey will attach to the lifter assembly . Wire monkeys will be rebent and secured through the lifter hole. Wood monkeys attach using a small wood screw. Determine the monkey length by holding it in place against the Sostenuto lifter and pressing the pedal plunger. The sostenuto Monkey rod should rotate freely from the inactive position to full sustain of the affected notes. Monkey Actuator
5. With the sostenuto in the inactive position, secure the cable conduit to the piano bed using the two loop clamps , about 1 inch back from the end. This allows for tension and stroke adjustment.

Prepare the Solenoid Rail (70050)
In this chapter, we determine the throw of the key solenoid plunger in relation to the piano actions key depth. We also walk through the process of key solenoid alignment with respect to the piano actions key tails. When this chapters work has been done, the solenoid rail will have the proper rail height and plunger throw. The mounting brackets will in placeand ready for mounting to the piano.
At this stage in the installation, the key frame has been notched, and the slots for each section cut and shaped. The piano remains on its side with the legs removed.
Tools needed for this chapter are a pencil, measuring tape, square, hacksaw, file and various screwdrivers.
The Pianomation Key Solenoid Rail (70050) is shipped assembled. Its component parts are as follows:
2 (70052) - 46.5" long structural rails with inside-face longitudinal grooves or notches running their full lengths 37 (70059) - 2-holed transverse diagonal cross-plates (key solenoid holders with mounted solenoids) 2 (70058) - 2-holed transverse diagonal cross-plates (key solenoid holders) 2 (70061) - 3-holed transverse diagonal cross-plates (key solenoid holders with mounted solenoids) 40 (70070) - white lead key solenoid coils with 40 star washers and 40 hex nuts 40 (70071) - black lead key solenoid coils with 40 star washers and 40 hex nuts 80 (70083) - Teflon coated key solenoid plungers with rubber tips 80 (70072) - 5/8" plastic threaded lost motion cap 80 (70054) - 8-32 x 1/2" key solenoid plate mounting bolts 80 (70056) - 8-32 x 11/32" key solenoid plate mounting nuts 160 (70074) - retaining cap internal rubber cushions
Tools needed include the 2 rail support brackets (70262 & 70264) a 11/32" nut driver, two (70078) rail bracket mounting screws, screwdriver, hacksaw, metal file, ruler and a pencil. The piano action is on your workbench and the keys are facing away from you.
Key Solenoid Plunger Throw Step 1. To take advantage of Pianomation's best reproducing capabilities, it is essential that the plunger throw matches the keytail lift. The difference in two measurements are required to accomplish this. A. The bottom of the keytail to the keybed in the key's full dip position. B. The bottom of the keytail to the keybed in the key's rest position.

Key Solenoid Plunger Throw
Step 2. Take the key lift measurement in step 1 and add 1/16" to compensate for keyfelt compression. This is the measurement used to find the rest position of the plunger.
Step 3. It is essential that the plunger extends out the top on the solenoid housing by 1/16" when in the "ON-HOLD" position (illustrated below). This will let the notes sustain their full duration. This step is very important when the system is being played in Magic Pedal™ mode.
1/16", .0625" Step 4. Hold the solenoid plunger in its "ON-HOLD" position. Position a scale stick or ruler to measure the movement /throw of the plunger. (**Ruler should be graduated in 1/32")
Step 5. Push the plunger into the solenoid by the measured amount of the key tail lift (Step 1) plus the 1/16" you added for felt compression.

Step 6. If the plunger falls flush with the housing or below (which will be in most cases), use the lost motion caps for adjustment. If the plunger is flush with the bottom of the solenoid housing, the lost motion cap can be screwed completely in. In the unusual event that the plunger would be above flush, use a 5/16" diameter felt disk (with center hole) to hold the plunger inside the solenoid bore.
Step 7. Adjust all lost motion caps to the same position. PART II. Installation and Alignment Procedures
Solenoid Rail Alignment
With the piano action on your workbench and the fronts of the keys facing away from you. Place the solenoid rail on the workbench in front of the keytails and put the plungers (70083) inside the solenoids. Turn the solenoid rail assembly on its side, so that the plungers are now parallel to the workbench surface and the rubber plunger tips are touching the back ends of the piano keys. Secure the rail with the two rail mounting plates supplied in your installers kit (70262 & 70264). Make sure the solenoid rail is centered with the center of the keyframe and mark the bass and treble ends. Make sure all the solenoid plates are free moving.
The spacing between sections has been held in check by the introduction of solenoid assembly pairs adjacent to the breaks. Because not all sections on a piano will have an even number of notes played in them, those which have an odd number will require a modified solenoid assembly to provide the additional note required, and this modified note will be placed adjacent to a section break or at either end.
Count the number of keys to be played in each section. If there is an even number, align the solenoids with plungers already on the rail with the centers of their respective key tails. If the number of keys to be played is odd, simply remove one of the solenoids from the double mounting bracket and continue to the alignment of the next section.
With a hack saw, cut away the unused portion of the rail ends if necessary, and file off all burrs with the metal file. Be careful not to cut away the rail bracket mounting holes, or cut any solenoid wires.
Mount all 8 rail support brackets (70062) to the rail with the 10-32 X 7/16" screws (70078) and #10 external star washers (70075).
Note: The distance from the bottom of the keybed to the bottom of the keytail felt should be equal to the distance from the top of the solenoid plunger to the top of the rail mounting brackets.
At this stage, the key solenoids have been matched up with their corresponding keytails. The rail has been cut to length, and the rail brackets attached in place. Put the rail aside for future installation in the piano. 12345

Solenoid Rail Installation
At this point, the rail has solenoid assembly pairs corresponding to active keys at either end of each action section and the rail has been previously cut to length. The piano is standing on its side; all of the electronics, mounting hardware and trapwork are in place and functioning.
Since the piano is resting on its left side, you can install the key solenoid rail easily by resting the bass- most (that is, the lowest) portion of the rail on the lowest end of the lowest slot and then bringing the treble-most part of the solenoid rail into the higher slots. The external parts of the rail assembly will take the brunt of the weight of the key solenoid rail and spare the more fragile internal structures. You can use a heavy-duty screwdriver inserted between the bass-most aspect of the lowest slot and the lowest part of the rail assembly as a simple wedge-lever to fine-tune the rail's precise alignment within the slot-system. Look inside the keyboard compartment to observe the alignment of the solenoid plungers alignment with their respective key-tails. If these are not satisfactory, you will have to remove the key solenoid rail assembly and place it back on the workbench in front of the keyframe-with-keys to correct any misalignment.
Once you are satisfied with these adjustments and the rail is properly aligned within the keybed slots, take a spring-loaded center punch or a sharp awl and carefully mark the centers of the four corner brackets, in the larger of the two holes in each bracket.
Next, fasten the four alignment screws with the large washers. This will allow you to move the solenoid rail 1/4" in all directions for fine alignment.
NOTE: The solenoid rail can be installed easily and more accurately when the piano is on its legs and the action is in place. However, an assistant may be required for this step.
In the case of uneven keytails, a lost motion adjustment can be made for each individual key. Each solenoid has a 5/8" nylon cap at the bottom of the solenoid. With the 5/8" socket wrench turn the nylon cap clockwise to raise the plunger tip or counter clockwise to lower the plunger tip. PART II. Installation and Alignment Procedures

In the case of the most Susceptibility (Volts) sensitive, it can take as little 30 volts to degrade or completely destroy the component. VMOS 30 TO 1800 MOSFET 100 TO 200 What do you have to do to build up a potentially GaAsFET 100 TO 300 destructive charge? It can take as little as sitting up EPROM 100 straight or lifting one foot off the floor.

How serious is the problem? Perhaps this will put it in perspective. Many people feel that static is no great problem because, with minimal static control procedures, they are able to keep the device failure rate to 0.5%. However, with 20 devices per board, this means 10% defective boards. With five boards per system, that translates to a system failure rate of 40%. Fortunately, the solution is not difficult. It is not necessary to ban plastic cups or visitors from the work areas. In fact, it would be impossible to eliminate all the potential carriers of static charge. Instead, all it takes is for everyone to observe two simple static control rules at all times.
RULE ONE: Handle all static-sensitive components at a static-safe work area.
RULE TWO: Transport all static-sensitive components is static-shielding carriers or packages.
RULE THREE: Always use a surge protector to protect your electronics from lightning strikes. PART II. Installation and Alignment Procedures

Installation of the Power Supply (70210), Processor Board (60100) & User Box (70395/70390)
At this point the piano is still on its side. The optional sustain pedal solenoid is in place. All the trapwork modifications have been completed and a clear passage has been made for installation of the solenoid rail.
Power Supply Mounting Having located the optional sustain pedal solenoid assembly, you can now locate the Power Supply chassis on the side of an adjacent wooden beam beneath the piano's soundboard. You should attempt to locate the Power Supply chassis as close to the belly-rail as possible so as to avoid exceeding the length of the related cables. Using the four #10 x 1" screws (70080) provided, secure the Power Supply chassis to the beam's side. Note: The power supply should be mounted in the direction that would allow for the cover to be removed for service. When mounting the power supply, make sure it does not touch the soundboard.
Processor Board Mounting Having located the Power Supply chassis, you can now locate the Processor Board chassis on the side of an adjacent wooden beam beneath the piano's soundboard. You should attempt to locate the Processor Board chassis as close to the belly-rail as possible so as to avoid exceeding the related cables lengths. Using the four #10 x 1" screws (70080) provided, secure the Processor Board chassis to the beam's side.
User Box Mounting The final chassis to install is the User Box. Typically, the User Control Box is installed slightly recessed from the front edge of the bottom of the keybed on the right side where it will not interfere with the pianist's right knee or on the Bass section of a grand piano so as not to be immediately visible, but still accessible. It should also be recessed in from the extreme right edge of the keybed-bottom to be as non-obtrusive as possible. Secure it with the two #10 x 1" screws (70080).

Key Note Driver Board Installation
Now it is time to turn your attention to the installation of the five printed circuit driver board chassis and note driver boards. There have been five Note Driver Mounting Brackets (70113), 5 Lock washers (70075) & 5 Truss head screws (70138) provided in the kit. These brackets are mounted in the center hole of each chassis. The lock washers are to be placed between the Note Driver Mounting Bracket and the Note driver Chassis. The note driver board chassis will be mounted to the Key Solenoid Locking nuts (70056) . Upon placement of each chassis be sure that all solenoid connectors will reach their respective header pins on the driver board.
Each 16-note driver board has 16 pairs of header pins, one header pair for every note. Start with the lowest key solenoid plug and plug it onto the lowest (that is, the left most) header pair. The next key solenoid plug should be the opposite wire color and it goes onto the next higher header pair. Continue this process for all 16 pair-positions on each board (Note: if there is a single solenoid at a break, there may be a wire color change.).
At this point, all boards have been mounted and connected to their respective key solenoid. Also, all electronic components, solenoid rail, and trap work have been mounted to the piano. You may now upright your piano to its legs.

Next, adjust the solenoid rail so that the plunger tips are approximately 1/32" away from the keytail felt. This step may not be necessary if accurate measurements were made t the time of attaching the mounting brackets. In the case of uneven keytails, a lost motion adjustment can be made for each individual key. Each solenoid has a 5/8" nylon cap at the bottom of the solenoid. With the 5/8" socket wrench turn the nylon cap clockwise to raise the plunger tip or counter clockwise to lower the plunger tip. PART II. Installation and Alignment Procedures
Dress the Cables l. Plug the female end of the 115 volt line cord (70214) into its recessed connector on the end of the Power Supply chassis or 230V for foreign installers.
2. Plug the appropriate end of the Note driver power cable (811437) into the labelled connector on the Power Supply and the five subsequent plugs into the five key solenoid driver boards, working from left to right. Connect the green lead with lug to the solenoid rail. See Test 2 under "Test & Alignment Procedures"
3. Plug the 108" DB37 Note driver signal cable (70319) into the Processor Board and then into each of the 5 key solenoid driver boards.
4. The 24" Power Supply to Processor Chassis cable (811434) connects the appropriate plugs of these two components.
5. Plug the 72" User Control Box to Processor chassis cable (70329) into its appropriate outlet.
6. Plug the 20 conductor 100" Installer Alignment Ribbon Cable (811435) into the Processor chassis.
7. The 6' cable with male RCA plugs (70131) at both ends connects your CD Player or CD Changer to the Control Panel.
8. The Sustain Pedal Solenoid plugs into the labelled connector on the Power Supply.
Once all of the above have been properly connected, you are ready to proceed with the Test & Alignment Procedures. (The rail, power supply chassis, and the processor box are already connected together and to AC ground by way of a line cord. There is no need to run separate ground wires to these components.)
The alignment of the system is very important if you want the system to play quiet. Alignment of the system also helps broaden the expression range. The next few pages will describe the alignment procedures. It will contain information on: 1. Test for solenoid shorts between the rail and the solenoid. 2. Test for shorts between the solenoid bobbin and the outer can. 3. Pedal solenoid short test 4. Pedal break-in 5. Test for note repeatability 6. Individual note power settings. PART II. Installation and Alignment Procedures
Solenoid Short Test Instructions (70259) SOLENOID SHORT TESTER
This Test Must Be Performed First! Before The System Is Powered Up.
The following instructions are for using the QRS Solenoid Short Tester to determine if any note solenoids are shorted to the note solenoid mounting rail or the sustain pedal solenoid is shorted to its frame.
1. UNPLUG THE SYSTEM TO DISCONNECT THE POWER SUPPLY FROM THE 115 OR 230 VOLT AC POWER SOURCE.
2. Briefly insert the tester probe into its 4-PIN connector to contact the internal pin. If the tester does NOT light up, replace two AA batteries or bulb as necessary.
3. Remove the 6-position "Rail Power" connector from the piano power supply and insert it in the mating 6-position receptacle of the tester.
4. Touch the tester probe to one of the solenoid mounting screws on the rail frame.
5. If the Tester lights up, one or more of the rail solenoids leads is shorted to the rail.
6. In order to identify the shorted solenoid(s), it must first be determined which driver board(s) control the shorted solenoid(s). a. Remove all of the 4-position power connectors from the driver boards. The tester should go dark. b. Starting at one end of the row of driver boards, connect and disconnect each 4-position power connector one at a time. If the Tester lights up at any connection, there is at least one shorted solenoid connected to that driver board.
7. Once the driver boards with shorted solenoids have been identified, individual shorted solenoids can be identified as follows: a. Connect the power cable to the individual driver board. The Tester will light. b. Remove and replace in order the individual 2-position solenoid connectors on the .... driver board. If, after removing a particular connector, the Tester light goes out, then that solenoid is shorted to the rail and must be replaced. If the light stays on continuously after removing and replacing all 16 connectors on the driver board, then more than one of the solenoids is shorted. c. If there are multiple shorts to a single driver board, remove all of the 2-pin connectors from the board. Connect and disconnect all 16 of them one at a time in order. The Tester will light up each time a shorted solenoid is connected. Shorted solenoids must be repaired or replaced. d. Repeat this procedure for other driver boards on which shorted solenoids were found.
8. To test the optional pedal solenoid, remove the 6-position rail power connector from the test box. Remove the 4-position "Sust. Pedal" connector from the power supply and insert it in the mating 4- postion receptacle of the Tester. Firmly touch the Tester probe to the pedal solenoid frame. If the Tester lights up, the solenoid is shorted to its frame and must be repaired or replaced. PART II. Installation and Alignment Procedures

Test and Alignment Procedures Test 1 (Transpose) Test 1 is generally the last in a series of tests to be performed when aligning the system. It puts the system in a mode almost identical to an installed system without the installer alignment box connected. The operating controls on the user box work normally. MIDI data or CDs may be played in and delayed MIDI received out. The only difference is that the Transpose function +24/-24 will change the relationship of the MIDI-In and the keys which respond. Transpose +24 will move the incoming MIDI signal up 2 octaves and transpose -24 will move it down 2 octaves. The middle portion of the Transpose +24/-24 switch leaves the MIDI note numbers unchanged. This function was designed to allow an installer to play or test the entire piano key range with a small portable MIDI keyboard.
Test 2 (System Check) Test 2 is the second test you perform. Be sure the power is off. This test prevents possible driverboard damage caused by shorted solenoids. The QRS Resistor box has two keyed connectors. One connector plugs into the power supply connector labeled "Note Driverboard Power". The other connector plugs into the note driverboard cable (811437). Turn the power on. The LEDs on the alignment box will flash a series of numbers. When the LEDs show "-02-" set the display switch "NOTE" and press "START TEST". The system will play all the notes once. Should a short be detected, the note number of the defective solenoid will be automatically displayed on the test alignment box LED. The system will then shut off the High Voltage. This particular solenoid must be replaced and the above test repeated until all the notes play successfully. The QRS Resistor Box should be connected only for this particular test. After the test, the system must be powered down and the power supply Low Voltage and High Voltage LED's must be allowed to go off. The QRS Resistor Box is then removed from the system. The driver board power cable plugged directly into the power supply; and the system turned on again.

Test and Alignment Procedures Test 3 (Full Scale Cycle) Test 3 plays each key sequentially and is good for breaking in the system. Press START TEST to activate the test. The Speed pot controls note duration and the Level pot directly controls loudness. If the Level pot is turned down, the saved (or default) minimum modulations may come into play and the note will use the current minimum instead of the Level pot value. The minimum default value is set at 25. If the Level pot is above the minimum, for any note, the note will play at the Level pot value. Putting the Display switch to "Level" will show the value being used. If the speed dial is turned to zero each key will be held down for 5 seconds in order to check for full key dip.
Momentarily pressing the Up Scale or Down Scale switch will change the direction of play. The Display switch changes the information shown on the display. Note # shows the solenoid number being played (5-84). Level displays the amount of power for the note. The center will display the note length in milliseconds.
Test 4 (Single Note Repeat) Test 4 repeatedly plays a single note. The SPEED, LEVEL and DISPLAY controls operate as in test 3. The Up Scale/Down Scale switch moves to the next note. The program sets a limit of 150 strikes per solenoid. This is to prevent overheating a single solenoid. If the limit is reached, the system will exit test 4 and blink: - 04 -. (Of course, one can always press the Start Test switch and play the same note 150 more times.) If the speed knob is set to zero, the note will stay held for 5 seconds.
Test 5 Tests 5 is for future use.
Test 6 (Pedal Solenoid Repeat) Tests 6 will continuously activate the pedal solenoid at the current power setting. This is a good test for the breaking in the pedal solenoid.
Test 7 (Diagnostics Printout) Test 7 will print out a system diagnostics status report to an IBM printer and is generally performed after the system has been aligned. An IBM compatible printer and cable must be connected to the installer Test & Piano Alignment Box. Press START TEST to begin printing. The printing routine does not use any special control codes, so it should print properly on most IBM compatible printers. The routine sends both carriage return and line feed commands. If the printer is not ready, the LED's will display "A30". After a few seconds, it will give up trying to print. The system may send some garbled codes during power up, causing the printer to go off line or print in an unexplained manner. For this reason, the printer should be turned on after the piano system is powered up.
The report title displays the version letter (currently E). If the report style changes in the future, the version letter will change. The report is in three sections. Except for diagnosing system problems, the second section will be the one of particular interest.
Test 8 (For future use) Test 8 is used to store the power settings for the optional soft shift pedal solenoid. This test responds exactly as in test 9 PART II. Installation and Alignment Procedures

Test 9 (Pedal Solenoid Power) Test 9 is used to adjust the power setting for the sustain pedal solenoid. This test is usually performed after test 2. The Display switch should be set to level. After the START TEST to activate the test. The LED's will display the current power setting for the sustain pedal. Use the Sustain Pedal switch on the User Box to actuate the pedal. To change the power level, press the ADJUST MINIMUM switch once. The "ADJUST MINIMUM" and "12 Store" decimal points will come on. Now the Level pot may be used to change the power setting. The LEVEL pot should be increased or decreased dependent on the power required to activate the sustain silently. The "12 STORE" decimal point will stay on to remind you to permanently save your changes to the processors memory (Test 12). To store the current setting into the processors memory turn to test 12 and press START TEST. The final setting should be doubled checked after the pedal has had a chance to warm up. Next, proceed to test 11.
Test 10 (Full Scale Minimum) Test 10 will play in manner similar to test 3. The notes will be playing at their current minimum power settings. These values are displayed with the DISPLAY switch set to level. The LEVEL pot does nothing now. If the minimums are too low, the notes may not play at all. If the minimum levels need changing, momentarily press the ADJUST MINIMUM Switch. The fourth decimal point will light as a reminder that you are in the adjust mode. The first decimal point will light to remind you to permanently store any adjustments you make. Now the Level pot will change the minimums for all notes that play. When a satisfactory balance has been reached, allow the piano to complete one more full keyboard sequence to apply the final chosen value to all of the notes. This completes the "gross" adjustment of the minimums. It is important to note that the new values are, at this point, only stored in the system's temporary memory. It is important to note that all power setting done in test 11 can be reprogrammed by this test. Permanent storage to EEprom is done in Test 12. If you don't want the new values stored, just turn the system off without doing Test 12. PART II. Installation and Alignment Procedures
Test and Alignment Procedures Test 11 (Single Note Minimum) Test 11 repeatedly plays individual notes so each key solenoid power level can be set. Upon entering this test, the piano will play in a manner similar to Test 4. A single note will begin playing at its currently power setting or at the default setting. If you want to change the power setting for that note, momentarily press the ADJUST MINIMUM Switch. The fourth decimal point will light as a reminder that you are in adjust mode. The first decimal point will light to remind you to permanently store the adjustments you make. Now the LEVEL pot will adjust the minimum power setting for the note that is playing. When you are satisfied with the lowest setting (hammer striking the string), momentarily press the UP SCALE or DOWN SCALE switch. The new value will be temporarily stored, and the piano will begin playing the next note at its current minimum. The adjust minimum decimal point will be off. In this test, the ADJUST MINIMUM switch must be pressed for each note that needs to be changed. Continue this process until all the notes play quietly and evenly. Permanent storage to the processors memory is done in test 12. If you don't want the new values to be stored, just turn the system off without doing Test 12.
Test 12 (Store to memory) Test 12 stores all the changed power settings into the processors memory. Press "START TEST" the permanent storage routine to begin. The "12 Store" decimal point (remember to save) will turn off, indicating that the changes have been "permanently" stored.
SPEED KNOB The speed knob is generally used most in test 11. It dictates the amount of time the solenoid is activated (50-140 milliseconds). While in test 11, a lower setting (140ms) will permit the system to play at a lower volume level and with a wider dynamic range. This is set to the 1 position throughout test 11
LEVEL KNOB The level knob is generally used most in test 11 and 9. It dictates how much power is going to be stored into the computers memory (i.e., key and pedal solenoid). While in test 11 and 9 determine by ear how much power is required to sufficiently strike the hammers against the strings. In the case of the pedal solenoid, set the power level so the pedal activates silently. These settings will be stored in the memory only after test 12 is performed.
TEST NUMBER KNOB This knob is used to select which test mode you want to access. PART II. Installation and Alignment Procedures
Mount the Lyre Braces
The lyre was originally braced to prevent a performer from pushing it toward the rear of the piano. These braces must now be reinstalled to prevent a pianist from pushing the lyre into the solenoid rail cover.
Tools needed include a screwdriver, saw, spray paint and tape measure. The original lyre braces and their brackets, wood screws and two pieces of wood are the parts required.
Two different methods of attaching the braces to the piano are recommended. The first attaches the braces to the underside of the keybed; the second attaches the braces to the underside of the solenoid rail cover. Read through each procedure before deciding which is best for your installation.
To attach the Lyre to the underside of the keybed:
Locate the points on the keybed where the original braces were seated.
Because the cover might be in the path of the braces to these two points, bend each brace in a gentle arc such that when the braces are placed into their seats on the lyre, their opposite ends come up just under their original mounting positions.
Measure the distance from the keybed to the brace bracket. Fill the distance with a block of the appropriate thickness, painted the color of the piano's keybed finish.
Attach the blocks to the underside of the keybed with wood screws.
Attach the lyre braces to the blocks.
At this point the installation is completed. Play the instrument for several hours to exercise the solenoids. You can use this time to verify that there are no squeaks in the trapwork and that all pusher tips are playing in the right key. The player unit will cycle continuously in test #3. You may also plug the left channel of a CD player to the analog in of the User Box and press play on the CD player while in Test 1. PART II. Installation and Alignment Procedures
Installation into an upright piano
This section outlines the differences between the installation of the QRS Pianomation MIDI retrofit kit in a grand piano versus an upright or vertical piano. The differences are relatively small, and an installer familiar with the procedure for installation in a grand piano should have no difficulty completing this type of installation.
The differences are as follows: 1. In a vertical or upright piano, the entire mechanism is hidden from view within the cabinetry of the piano itself, and consequently the installer can place the components anywhere it makes sense to do so.
2. Since the mechanism is hidden from view, no solenoid rail cover is required.
3. The trapwork is very different from that of a grand piano, and requires the installer to use a special pedal solenoid made specifically for the upright or vertical.
4. In a vertical piano, the entire kit is installed below the keybed. In most cases, the back rail and back rail cloth should be relocated toward the back edge of the piano keys. IMPORTANT******** care must be taken to first measure the key dip at the back end of the keys before any work begins. Secondly, after the back rail has been relocated, you must ensure that the key dip is exactly the same as it was before starting. If it is not, you must either trim the back rail or shim it up to its original measurement.
5. Special upright / vertical driver board mounting brackets are required for mounting the driver boards to the solenoid rail. These brackets are 3” long and will allow the driver board and chassis to hang below the solenoid rail when completed.
6. SPECIAL NOTE**** If the driver boards are mounted upside down, you can reverse the playing order of the notes by simply depressing DIP switch #1 on the processor board and resetting the system by turning it off and on again.
7. The power supply and the processor board are mounted inside the cabinet of the piano in any place convenient to the installer. Make sure the electrical cables do not interfere with any of the mechanical levers within the piano.
8. It is necessary to cut a 1” hole directly through the soundboard of the piano towards the bottom of the piano at the end where the power supply is mounted. This will allow the main power plug to easily be plugged into a wall outlet. This hole will not affect the sound of the piano in any way.
9. Alignment of the solenoid rail is made by laying a wooden stick at the top back edge of the keys and carefully transferring the centerline of each key onto the wooden stick. This stick will become your alignment stick, and these marks will be used to locate the proper position for you solenoids. Remember that a standard installation is 80 notes and the pianos 88 notes. Start with note #5 and end with note #84 and slide each pair of solenoids in direct alignment with your marks on the alignment stick and tighten the 11/32” nuts. PART II.

INTRODUCTION
This section contains instructions for installing and operating the Wireless System. Please read it thoroughly before attempting to operate your system for the first time.
T6 RECEIVER SETUP AND CONNECTIONS
1. The reciever can be mounted to the piano using screws or the hook-and-loop strips provided. Complete all adjustments before mounting.
2. Locate the receiver so that it is away from metal surfaces and obstructions, since they will degrade the wireless performance. The receiver can be mounted horizontally or vertically. Typical location for grand pianos is the belly rail with the antenna downward.
3.Fully extend the receiver's antenna vertically. If possible make sure the antenna is in the line-of- sight of the transmitter.
4.Connect the receiver AUDIO OUT to the ANALOG IN on the User Box. Use the phono to RCA cord provided.
5.Connect the AC power adapter to the receiver's power connector and plug it into an AC electrical outlet, located on the Power Supply.
OPERATING THE SYSTEM
1.Plug the receiver's AC adapter into an AC power source. The green POWER light on the receiver will illuminate.
2.Set transmitter POWER and MIC switches to the "on" position. Use the attenuating adaptor at the CD player output. The green POWER light on the transmitter will illuminate, indicating power.
3.Verify that the yellow RF light on the receiver is steadily illuminated, indicating that the transmitter signal is being received. NOTE: A flickering RF light indicates marginal operation. To achieve optimum reception, turn the SQUELCH adjustment on the receiver with a small screwdriver. You may need to relocate the receiver so that it is within the line-of-sight of the transmitter. If necessary, reduce the distance between the transmitter and receiver until the RF light is steadily illuminated.
4.While the CD player is operating, verify that the red PEAK light on the receiver flickers only on loud peaks. If necessary, adjust the audio gain setting on the back of the transmitter until the PEAK light just comes on. PART III. Installation of Optional Accessories
Powered Speaker (Cat. No. 70040)

Pianomation Maintenance As a dealer and/or technician of Pianomation, you will find our system to require very little maintenance, although there are a few things worth mentioning.
1. Check solenoid plunger to key lost motion. If necessary adjust for minimum lost motion without causing contact between the Plunger tip and the keyfelt.
2. Check wire harness connections and plugs to see that they are properly seated.
3. A. With the test and alignment box, run through each key solenoid to check for proper operation. B. If the piano action has been worn in, you may want to reset low end of power setting. C. Hookup IBM compatible printer to the alignment box and check for error counts as well as to document your service call.
4. Lubricate mechanical moving parts of trapwork and cables where they travel through the cable conduct.
5. Give a thorough cleaning of dust and dirt buildup on and around the circuit boards or solenoids.
Caution must be used not to create static charges that could damage sensitive components. We suggest using canned CO2 or dry air that is specially made for this task. There are many types available at most electronic supply houses. PART III. Pertinent Information
