Many electrical and mechanical parts in thischassis have special safety characteristics thatoften pass unnoticed and the protectionafforded by them cannot necessarily beobtained by using replacement componentsrated for higher voltage, wattage, etc.Replacement parts that have these specialsafety characteristics are identified in thismanual and its supplements: electricalcomponents having such features are identifiedby in the schematic diagram and the partslist.Before replacing any of these components,read the parts list in this manual carefully. Theuse of substitute replacement parts that do nothave the same safety characteristics asspecified in the parts list may create shock, fire,or other hazards.2. Before returning the set to the customer,always do an AC leakage current check on theexposed metal parts of the cabinet, such asterminals, screw heads, and metal overlays, tobe sure the set is safe to operate danger ofelectrical shock. Plug the AC line cord directlyinto a 120 V AC outlet(USA Version) or 230 VAC outlet(EU Version). (Do not use a lineisolation transformer during this check.) Be sureyour AC voltmeter has a sensitivity of 5000 per volt or greater. Then connect a 1500 10watt resistor, paralleled by a 0.15 F 150 V ACcapacitor, between a known good earthground(such as a water pipe, or conduit) and theexposed metallic parts, one at a time. Measurethe AC voltage across the combination of a 1500 resistor and a 0.15 F capacitor. Reverse theAC plug at the AC outlet and repeat AC voltagemeasurements for each exposed metalic part.Voltage measured must not exceed 0.75 VRMS. This corresponds to 0.2 mA AC. Anyvalue exceeding this limit constitutes a potentialshock hazard and must be correctedimmediately.RadioFans.CN 收音机爱 好者资料库Model : AVR-133BLOCK DIAGRAMWIRING DIAGRAMModel : AVR-133UPD78F0536GK : IC1011.
