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.

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DV-444, DV-44032.1 PACKING 1Power CordADG70222Audio Cord (L = 1.5m)See Contrast table (2)3Video Cord (L = 1.5m)See Contrast table (2)4Remote Control UnitSee Contrast table (2)5Battery CoverSee Contrast table (2)NSP6Dry Cell Battery (R6P, AA)See Contrast table (2)7PadVHA1285NSP8Warranty CardARY70459Packing CaseSee Contrast table (2)10Mirror Mat (0.5 750 600)Z23-00711 12Polyethylene BagVHL1051(0.03 200 300)13Operating InstructionsSee Contrast table (2)14Operating InstructionsSee Contrast table (2)(1) PACKING PARTS LISTMark No. Description Part No.2.
