RadioFans.CN 收音机爱 好者资料库SAFETY PRECAUTIONSWARNINGBefore servicing this unit, familiarize yourself with the following precautions:1. 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, readthe parts list in this manual carefully. The use ofsubstitute replacement parts that do not havethe same safety characteristics as specified inthe parts list may create shock, fire, or otherhazards.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.) Besure your AC voltmeter has a sensitivity of5000 per volt or greater. Then connect a1500 10 watt resistor, paralleled by a 0.15F 150 V AC capacitor, between a known goodearth ground(such as a water pipe, or conduit)and the exposed metallic parts, one at a time.Measure the AC voltage across the combinationof a 1500 resistor and a 0.15 F capacitor.Reverse the AC plug at the AC outlet andrepeat AC voltage measurements for eachexposed metalic part. Voltage measured mustnot exceed 0.75 V RMS. This corresponds to0.2 mA AC. Any value exceeding this limitconstitutes a potential shock hazard and mustbe corrected immediately.2RadioFans.CN 收音机爱 好者资料库Measuring methods are based on IHF and IEC standard 268-3Measurements conditions,unless otherwise noted : Output resistive load = (6) ohms / Both channel driven Tone Direct ON , Other SWs : OFFPower figures should be kept minimum 10min. between 15 and 35cFilter : IHF-A filter,R/O = Rated OutputPower supply : 240 V / 50 Hz 1.
