3、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 preformed repairs can adversely affect the safety and reliability of the product and

4、may void the warranty. If you are not a 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 Lead in solder used in this product is listed by the California Health and Welfare agency a

5、s a known reproductive toxicant which may cause birth defects or other reproductive harm (California Health & Safety Code, Section 25249.5). When servicing or handling circuit boards and other components which contain lead in solder, avoid unprotected skin contact with the solder. Also, when solderi

6、ng do not inhale any smoke or fumes produced. 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.

(FOR USA MODEL ONLY) 1.SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Measure lea

8、kage current to a know 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 A

9、C line cord of the appliance directly into a 120V AC 60Hz outlet and turn the AC power switch on. Any current measured must no exceed 0.5mA. ANY MEASUREMENT NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RERTURNING THE APPLIANCE TO THE CU

10、STOMER. 2.PRODUCT SAFETY NOTICE Many electrical and mechanical parts in the appliance have special safety related characteristic. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, watt

11、age, 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 D on the schematics and on the parts list in this Service Manual. The use of a substitute replacement compone

12、nt which dose not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create sock, fire, or other hazards. Product Safety is continuously under review and new instructions are issued from time to time. For the latest in
