It has ben assumed that basic service procedures inherent to the industry, and morc specifically YAMAHA Products, are already known md understood by the uwrs, and have therefore not bcen restated. WARNING: Failure to follow appropriate service and safety procedurcs when seruicing this product may result in personal injury, destruction of expensive components, and failure of the product to perform as specified. For these reasons, we advise all YAMAHA product owners that any seruice required should be perfomed by an authorized YAMAHA Retailer or the appointed seruice representative. IMPORTANT: The presentation or sale of this mmual to any individual or fim does not constitute authoriza- tion, cenification or recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form. The data provided is believed to be accumte and applicable to the unit(s) indicated on the cover. The reseach, engineering, and service depanmenb of YAMAHA arc continually striving to imprcve YAMAHA products. Modifications are, tbereforc, inevitable and specifications are subject to change without notice or obligation !o retrofit. Should any discrepancy appear to exist, please coniact the distributors Seruice Division. WARNING: Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this buss). IMPORTANT: Tum the unit OFF during disassembly md part replacement. Recheck all work before you apply power to the unit, YAMAHA YAMAHA CORPORATION P.O.Box1 .Hamamatsu,Japan 3.05K-203 ffl Q Prinred in Japan ll q/W li oo4ssl RadioFans.CN 收音机爱 好者资料库 cx-1 I TO SERVICE PERSONNEL 1. Critical Components Informalion. AC LEAKAGE Components having special characteristics are marked and WALL EqUIpMENT TESTER OR must be replaced with parts having specificalions equal to OUTLET UNDER TEST EQUIVALENT those originally installed. 2. Leakage Current Measurement (For 120V Models Only). When service has been completed, it is imperative to veriy that all exposed conductive surfaces are properly insulated lrom supply circuits. o Meter impedance should be equivalenl lo 1500 ohm shunted by 0.15pF. o Leakage current must not exceed 0.5mA. o Be sure to test for leakage with the AC plug in both oolarities. -TNSLiLATTNG TABLE WARNING: CHEMICAL CONTENT NOTICE! The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm. DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVERI Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/f lux vapor! lf you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food.
