PDV-LC10 2 1. SAFETY INFORMATION 1. SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A PO- TENTIAL SHOCK HAZARD AND MUST BE COR- RECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER. 2. PRODUCT SAFETY NOTICE Many electrical and mechanical parts in the appli- ance have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be ob- tained by using replacement components rated for voltage, wattage , etc. Replacement parts which have these special safety characteristics are identified in this Service Manual. Electrical components having such features are identified by marking with a on the schematics and on the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards. Product Safety is continuously under review and new instructions are issued from time to time. For the latest information, always consult the current PIONEER Service Manual. A subscription to, or ad- ditional copies of, PIONEER Service Manual may be obtained at a nominal charge from PIONEER. LEAKAGE CURRENT CHECK Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester such as Simpson Model 229-2 or equivalent between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60 Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5 mA. (FOR USA MODEL ONLY) Also test with plug reversed (Using AC adapter plug as required) Device under test Test all exposed metal surfaces Earth ground Leakage current testerReading should not be above 0.5 mA AC Leakage Test This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual. Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty. If you are not qualified to perform the repair of this product properly and safely, you should not risk trying to do so and refer the repair to a qualified service technician. WARNING This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to cause cancer, birth defects or other reproductive harm. Health & Safety Code Section 25249.6 Ð Proposition 65 REMARQUE (POUR MODéLE CANADIEN SEULEMENT) Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que les pices de remplacement doivent avoir la mme dŽsignation. NOTICE (FOR CANADIAN MODEL ONLY) Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement parts must be of identical designation.

PDV-LC10 3 LABEL CHECK ZY Type Only : VRW1796 ZY Type Only : VRW-328 VRW1805 ZU/CA Type Only : To Reverse sideLABEL Additional Laser Caution 1. Laser Interlock Mechanism If the switch to detect door-open state (S603: DISC OPEN DET) is open, the laser interlock mechanism operates and shuts down the power source (Q100) to the laser diode drive circuit. The system microcomputer detects this condition and does not issue the Laser On command. If Q100 is defective, accompanying a short-circuit between the emitter and the collector, the system microcomputer judges this status as the door-open state, and it does not issue the Laser On command as long as Q611 is not defective, even if S603 is open. Therefore, the laser does not light unless S603 is intentionally short-circuited in door-open state. To light the laser in Test mode, short-circuit S603. Hold S603 in the depressed position from the top, as it is a push switch. 2. NEVER directly look at the objective lens from a short distance when lighting the laser by short-circuiting S603 in door-open state. CAUTION : LASER RADIATION WHEN OPEN, AVOID LONG-TERM VIEWING OF DIRECT LASER RADIATION. CAUTION : USE OF CONTROLS OR ADJUSTMENTS OR PER- FORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. LASER DIODE CHARACTERISTICS FOR DVD : MAXIMUM OUTPUT POWER : 3.2 mw WAVELENGTH : 650 nm FOR CD : MAXIMUM OUTPUT POWER : 3.3 mw WAVELENGTH : 780 nm CAUTION : TO PREVENT RISK OF ELECTRIC SHOCK AND LASER EXPOSURE, DISCONNECT THE AC ADAPTER OR THE BATTERY BEFORE REMOVE SCREWS. LASER RADIATION WHEN OPEN, AVOID LONG-TERM VIEWING OF DIRECT LASER RADIATION. < VRW1815 > CAUTION ZU/CA type Only : VRW1815
