Qualified technicians have the necessary test equipment and tools, and have beentrained 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 mayvoid the warranty. If you are not qualified to perform the repair of this product properly and safely, youshould not risk trying to do so and refer the repair to a qualified service technician.WARNINGThis product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California tocause cancer, birth defects or other reproductive harm. Health & Safety Code Section 25249.6 Proposition 65NOTICE(FOR CANADIAN MODEL ONLY)Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacementparts must be of identical designation.REMARQUE(POUR MODLE CANADIEN SEULEMENT)Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent queles pices de remplacement doivent avoir la mme dsignation.ANY MEASUREMENTS NOT WITHIN THELIMITS OUTLINED ABOVE ARE INDICATIVEOF A POTENTIAL SHOCK HAZARD ANDMUST BE CORRECTED BEFORE RETURN-ING THE APPLIANCE TO THE CUSTOMER.2. PRODUCT SAFETY NOTICEMany electrical and mechanical parts in the appliancehave special safety related characteristics. These areoften not evident from visual inspection nor theprotection afforded by them necessarily can be obtainedby using replacement components rated for voltage,wattage, etc. Replacement parts which have thesespecial safety characteristics are identified in thisService Manual.Electrical components having such features areidentified 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 in theparts list in this Service Manual, may create shock, fire,or other hazards.Product Safety is continuously under review and newinstructions are issued from time to time. For the latestinformation, always consult the current PIONEERService Manual. A subscription to, or additional copiesof, PIONEER Service Manual may be obtained at anominal charge from PIONEER.(FOR USA MODEL ONLY)1. SAFETY PRECAUTIONSThe following check should be performed for thecontinued protection of the customer and servicetechnician.LEAKAGE CURRENT CHECKMeasure 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, control shaft, etc.). Plugthe AC line cord of the appliance directly into a 120VAC 60 Hz outlet and turn the AC power switch on. Anycurrent measured must not exceed 0.5 mA.DeviceundertestLeakagecurrenttesterEarthgroundReading shouldnot be above0.5 mAAlso test withplug reversed(Using AC adapterplug as required)Test allexposed metalsurfacesAC Leakage TestRadioFans.CN 收音机爱 好者资料库 VSX-AX5i-S356785678CDFABE CONTENTS SAFTY INFORMATION.21.
