PRODUCT SAFETY NOTICE Many electrical and mechanical parts in the appli-ance have special safety related characteristics. Theseare often not evident from vi

6、sual inspection nor theprotection afforded by them necessarily can be ob-tained by using replacement components rated forvoltage, wattage , etc. Replacement parts which havethese special safety characteristics are identified inthis Service Manual. Electrical components having such features areidenti

7、fied by marking with a on the schematics andon the parts list in this Service Manual.The use of a substitute replacement component whichdoes not have the same safety characteristics as thePIONEER recommended replacement one, shown inthe parts list in this Service Manual, may create shock,fire, or ot

8、her hazards. Product Safety is continuously under review andnew instructions are issued from time to time. Forthe latest information, always consult the currentPIONEER Service Manual. A subscription to, or ad-ditional copies of, PIONEER Service Manual may beobtained at a nominal charge from PIONEER.

9、LEAKAGE CURRENT CHECK Measure leakage current to a known earth ground(water pipe, conduit, etc.) by connecting a leakagecurrent tester such as Simpson Model 229-2 orequivalent between the earth ground and all exposedmetal parts of the appliance (input/output terminals,screwheads, metal overlays, con

10、trol shaft, etc.). Plugthe AC line cord of the appliance directly into a 120VAC 60 Hz outlet and turn the AC power switch on.
