SAFETY INFORMATIONThis service manual is intended for qualified service technicians ; it is not meant for the casual do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trainedto 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 to causecancer, 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 replacement parts mustbe 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 que les picesde remplacement doivent avoir la mme dsignation.ANY MEASUREMENTS NOT WITHIN THE LIMITSOUTLINED ABOVE ARE INDICATIVE OF A POTENTIALSHOCK HAZARD AND MUST BE CORRECTED BEFORERETURNING THE APPLIANCE TO THE CUSTOMER.2. PRODUCT SAFETY NOTICE Many electrical and mechanical parts in the appliancehave special safety related characteristics. These areoften not evident from visual inspection nor the protectionafforded by them necessarily can be obtained by usingreplacement components rated for voltage, wattage, etc.Replacement parts which have these special safetycharacteristics are identified in this Service Manual. Electrical components having such features are identifiedby marking with a on the schematics and on the parts listin this Service Manual.The use of a substitute replacement component which doesnot have the same safety characteristics as the PIONEERrecommended replacement one, shown in the parts list inthis 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 PIONEER ServiceManual. A subscription to, or additional copies of, PIONEERService Manual may be obtained at a nominal charge fromPIONEER.1. SAFETY PRECAUTIONS The following check should be performed for thecontinued protection of the customer and servicetechnician.LEAKAGE CURRENT CHECK Measure leakage current to a known earth ground (waterpipe, conduit, etc.) by connecting a leakage current testersuch as Simpson Model 229-2 or equivalent between theearth ground and all exposed metal parts of the appliance(input/output terminals, screwheads, metal overlays, controlshaft, etc.). Plug the AC line cord of the appliance directlyinto a 120V AC 60Hz outlet and turn the AC power switchon. Any current measured must not exceed 0.5mA.(FOR USA MODEL ONLY)LeakagecurrenttesterReading shouldnot be above0.5mADeviceundertestTest allexposed metalsurfacesAlso test withplug reversed(Using AC adapterplug as required)EarthgroundAC Leakage TestRadioFans.CN 收音机爱好者资料库3VSX-29TX, VSX-27TX, VSX-26TX,VSX-24TX, VSX-D908S2.1 PACKING2. EXPLODED VIEWS AND PARTS LISTNOTES: Parts marked by NSP are generally unavailable because they are not in our Master Spare Parts List. The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. Screws adjacent to mark on the product are used for disassembly.VSX-29TXOther Models123, 12Refer to7.3 REMOTE CONTROL UNIT.Refer to7.3 REMOTE CONTROL UNIT.11654851213133, 1211105410131397 (1/2)7
