If the label on the top of the Workabout displays the words "FCC ID:" followed by a code, then it complies to the limits for a Class B computing device in accordance with the specifications in Part 15 of FCC rules. If "FCC ID:" does not appear on the label, it complies to Class A limits. See the statements below for further details. Limits for Class A computing devices This equipment has been tested and found to comply with the limits for a Class A computing device pursuant to part 15 of the FCC Rules. These are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at his own expense. Limits for Class B computing devices This equipment has been tested and found to comply with the limits for a Class B computing device pursuant to Part 15 of FCC Rules. These are designed to provide reasonable protection against harmful interference in a residential installation. This equipment can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: *) Reorient or relocate the receiving antenna. *) Increase the separation distance between the equipment and the receiver. *) If you are using the Workabout with a mains adaptor, plug it into an outlet which is on a different circuit from that to which the receiver is connected. *) Consult an authorised Psion dealer or an experienced radio/television technician for help. Important This equipment was tested for FCC compliance under conditions that included the use of shielded cables and connectors between it and any peripherals that are attached. It is important that you use shielded cables and connectors to reduce the possibility of causing Radio and Television interference. Shielded cables, suitable for the Workabout, can be obtained from an authorised Psion dealer. If the user modifies the Workabout computer or its Expansion Modules in any way, and these modifications are not approved by Psion, the FCC may withdraw the user's right to operate the equipment. For customers in the USA, the following booklet prepared by the Federal Communications Commission may be of help: "How to Identify and Resolve Radio-TV Interference Problems". This booklet is available from the US Government Printing Office, Washington, DC 20402 Stock No 004-000-00345-4. Introduction You should read this chapter first; it contains basic information that you need to know before you read the other chapters in this manual. In this chapter you will find details about: The various Workabout components. Fitting the the Workabout's batteries and connecting it to the mains. The notational conventions used in this manual are as follows: Wherever there are things for you to do, the instructions appear as a numbered list. Extra notes, which you may find useful, are preceded by a "+" symbol. Important information is indicated by the word Important:, or is printed in bold type. Technical or jargon terms appear in italic type the first time that they are referred to in the text. To move quickly to information about a specific subject, look in the index for an appropriate entry. Index entries are grouped according to topics; for example, to find out about batteries, look for an appropriate entry under the major entry "Batteries". ------------------------------------ ************ About the Workabout The Workabout is a robust handheld computer which uses the same Solid State Disks (SSDs) as the Psion HC and Series 3 ranges. Its advanced windowing and multi-tasking software system makes it simple to use and easy to integrate with existing computer systems. *** Package contents In the Workabout box you will find: *) The Workabout *) This User Guide *) A lithium backup battery *) A Warranty leaflet *** Care of the Workabout The Workabout is dust proof and splash proof. Should you ever need to clean it, first turn it off and then gently wipe the keyboard and screen with a soft, clean, dry cloth. ****** Where things are The following diagram shows where the main components of the Workabout are: (picture) (picture) ------------------------------------ ************ Powering the Workabout The Workabout can be powered in four ways: *) by two AA batteries (not supplied). You should use alkaline batteries for best results. *) by a Psion Ni-Cd (Nickel-Cadmium) rechargeable battery pack, supplied separately from the Workabout (Part no. 2802-0005). You can also use 2 standard Ni-Cd rechargeable batteries, however, you cannot recharge these batteries while they are fitted in the Workabout and so they are not recommended for use. *) by the AC (mains) supply via a Docking Holster (Part no. 1804-0003-01) and Workabout mains adaptor (Part no. 2502-0010 for use in the U.K. Part no. 2502-0011 for use in the rest of Europe). Neither the Docking Holster nor the mains adaptor are supplied with the Workabout, they must be purchased separately; see your Psion distributor for more information. *) by placing it in a Workabout Docking Station. A small lithium battery is supplied as a backup battery (battery type: 3V Lithium R16 battery - CR1620). When there is no other power supply, it will preserve information in the Workabout's internal memory (RAM) for approximately five days. Important: When the main batteries and backup battery are removed, all the information in the internal memory (RAM) is lost. Before removing both batteries, you should therefore copy any important information in the internal memory to an SSD or PC. If you plan not to use the Workabout for long periods of time, it is best to copy all the data on the internal disk (M:) to an SSD and then remove both the main and backup batteries. *** Fitting / changing the backup battery When the backup battery supplied with the Workabout becomes discharged, you must replace it with the same or an equivalent type of battery as recommended by Psion. You can purchase them from your Psion distributor (Part no. 4900-0018, description BAT LITH. 3V 60mAH 2x16D) or from other battery stockists (Battery type: 3V Lithium R16 [CR1620]). The backup battery is located in a slot in the SSD/Battery drawer that slides out of the centre of the Workabout. To fit it: 1. Turn the Workabout off. 2. Press down the SSD/Battery drawer release button (on the left hand side of the screen) to release the drawer and pull it out until the backup battery cover is revealed. 3. Slide open the backup battery cover in the direction indicated by the arrow, then fit the backup battery into its slot as shown in the following diagram: (picture) Important: Make sure that the positive terminal of the backup battery (the flatter of the two sides and marked with a + symbol) faces towards the outer edge of the Workabout as you insert it. There is a risk of explosion if you incorrectly replace lithium batteries. 4. Slide the backup battery cover back into its original position to secure the battery in place. 5. Close the SSD/Battery drawer. Warning: You should tape, or otherwise protect the terminals of discharged lithium batteries before you dispose of them. Do not incinerate or crush them, or attempt to recharge them. *** Fitting / changing the main batteries Rechargeable Ni-Cd battery packs are normally not charged when new. So if you are fitting a new one, you will probably need to charge it first. See the `Recharging a Ni-Cd battery pack' section for details of how to do this. When the main batteries become discharged and need to be replaced, you should leave them in the Workabout until you are ready to fit charged batteries; this will prolong the life of the backup battery. The backup battery preserves the contents of the internal memory while the main batteries are being changed; however, you should not rely upon it as a permanent source of power. The main batteries (or rechargable Ni-Cd battery pack) fit in a recess in the SSD/Battery drawer that slides out of the centre of the Workabout. To fit or change the main batteries: 1. Turn the Workabout off, then press down the SSD/Battery drawer release button to open the SSD/Battery drawer and pull it out until the main battery compartment is visible.
