This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer. Oualified technicians have the neces- sary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual. lmproperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty. lf 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. WARN I NG Lead in solder used in this product is listed by the California Health and Welfare agency as a known reproductive toxicant which may cause birth defects or other reproductive harm (Cafifornia Health & Safety Code, Section 2S24g.Sl. When servicing or handling circuit boards and other components which contain lead in solder, avoid unprotected skin contact with the solder. Also, when soldering do not inhale any smoke or fumes produced. 1. SAFETY INFORMATION (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 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 1 2OV AC 6OHz outlet and turn the AC power switch on. Any current measured must not exceed O.SmA. Reading should not be above O.5mA Test all exposed metal surfaces 2-wire cord 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 vol- tage, 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 A on the schematics and on the parts list in this Service Manual. The use of a substitute replacement component 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 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.
