PRODUCT SAFETY NOTICE Many electrical and mechanical parts in the appli-ance have special safety related characteristics. Theseare often not evident from visual inspection nor theprotection afforded by them

9、 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 areidentified by marking with a on the schematics andon the

10、 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 other hazards. Product Safety is continuously under
