RadioFans.CN 收音机爱 好者资料库 SAFETY PRECAUTIONS WARNING Before servicing this unit, familiarize yourself with the following precautions: 1. Many electrical and mechanical parts in this chassis have special safety characteristics that often pass unnoticed and the protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts that have these special safety characteristics are identified in this manual and its supplements: electrical components having such features are identified by in the schematic diagram and the parts list. Before replacing any of these components, read the parts list in this manual carefully. The use of substitute replacement parts that do not have the same safety characteristics as specified 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 the exposed metal parts of the cabinet, such as terminals, screw heads, and metal overlays, to be sure the set is safe to operate danger of electrical shock. Plug the AC line cord directly into a 120 V AC outlet(USA Version) or 230 V AC outlet(EU Version). (Do not use a line isolation transformer during this check.) Be sure your AC voltmeter has a sensitivity of 5000 per volt or greater. Then connect a 1500 10 watt resistor, paralleled by a 0.15 F 150 V AC capacitor, between a known good earth ground(such as a water pipe, or conduit) and the exposed metallic parts, one at a time. Measure the AC voltage across the combination of a 1500 resistor and a 0.15 F capacitor. Reverse the AC plug at the AC outlet and repeat AC voltage measurements for each exposed metalic part. Voltage measured must not exceed 0.75 V RMS. This corresponds to 0.2 mA AC. Any value exceeding this limit constitutes a potential shock hazard and must be corrected immediately. 2 RadioFans.CN 收音机爱 好者资料库 Measuring methods are based on IHF and IEC standard 268-3 Measurements conditions,unless otherwise noted : Output resistive load = (6) ohms / Both channel driven Tone Direct ON , Other SWs : OFF Power figures should be kept minimum 10min. between 15 and 35c Filter : IHF-A filter,R/O = Rated Output Power supply : 240 V / 50 Hz 1.
