SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service tec

7、hnician. 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 characteris

8、tics. 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. Electr

9、ical 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

10、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 Servic

11、e 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 ap

12、pliance (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. Also test with plug reversed (Using AC adapter plug as required

13、) Device under test Test all exposed metal surfaces Earth ground Leakage current tester Reading 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

14、 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 th

15、is product properly and safely, you should not risk trying to do so and refer the repair to a qualified service technician.

SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY INSTRUCTED PERSON. LASER DIODE CHARACTERISTIC

17、S FOR DVD : MAXIMUM OUTPUT POWER : 7 mW WAVELENGTH : 650 nm FOR CD :MAXIMUM OUTPUT POWER : 5mW WAVELENGTH : 780 785 nm LABEL CHECK Additional Laser Caution 1. Inside detection switch (S201 on the INSB assy) and loading- status detection switch (S301 on the LOSB assy) are detected by the microprocess

18、or (IC501 in the DVDM assy). To permit the laser diode to oscillate, it is required to set the inside detection switch for the inside position (S201 : ON) and to set the loading-status detection switch for the clamp position (the center terminal of S301 is shorted to +5V). The laser diode oscillatio

19、n will continue if pin 13 of IC101 is shorted to +5V (fault condition) in the DVDM assy. In the test mode , the laser diode oscillates when microproces- sor detects a PLAY signal, or when the PLAY key is pressed (S5901 ON in the FRONT(1) assy), with the above requirements satisfied. 2. When the cove

20、r is open, close viewing through the objective lens with the naked eye will cause exposure to the laser beam. : Refer to page 94.
