FOR A COMPLETE DESCRIPTION OF THE OPERATION OF THIS UNIT, PLEASE REFER TO THE OPERATION MANUAL. IMPORTANT SERVICE NOTES BEFORE RETURNING THE AUDIO PRODUCT (Fire & Shock Hazard) Before returning the audio product to the user, perform the following safety checks. 1. Inspect all lead dress to make certain that leads are not pinched or VTVM that hardware is not lodged between the chassis and other metal AC SCALE parts in the audio product. 2. Inspect all protective devices such as insulating materials, cabinet, terminal board, adjustment and compartment covers or shields, 1.5k ohms mechanical insulators etc. 10W 3. To be sure that no shock hazard exists, check for leakage current in the following manner. * Plug the AC line cord directly into a 120 volt AC outlet. * Using two clip leads, connect a 1.5k ohm, 10 watt resistor paralleled 0.15 µ F by a 0.15µF capacitor in series with all exposed metal cabinet parts TEST PROBE CONNECT TO and a known earth ground, such as conduit or electrical ground TO EXPOSED KNOWN EARTH connected to earth ground. METAL PARTS * Use a VTVM or VOM with 1000 ohm per volt, or higher, sensitivity GROUND to measure the AC voltage drop across the resistor (See diagram). All check must be repeated with the AC line cord plug connection * Connect the resistor connection to all exposed metal parts having a reversed. return path to the chassis (antenna, metal cabinet, screw heads, Any reading of 0.3 volt RMS (this corresponds to 0.2 milliamp. AC.) knobs and control shafts, escutcheon, etc.) and measure the AC or more is excessive and indicates a potential shock hazard which voltage drop across the resistor. must be corrected before returning the audio product to the owner.

– 45 – MD-R2 TROUBLE SHOOTING When MD fails operate If the objective lens of optical pickup is contaminated, MD may fail to operate. At first, clean the objective lens to check playback operation. If MD fails persistently to operate, perform checks as follows. If dust or foreign substance is accumulated on the pickup lens, playback is disturbed and indication of TOC (content of tracks) may be disabled. Before adjusting check that the lens is clean. If the lens is contaminated, treat it as follows.

Turn off power supply, impregnate the lens cleaning paper with a small quantity of isopropyl alcohol, and gently wipe the lens with it with due care so that the lens is not damaged. At this time do not touch the lens directly with your finger.
