For these reasons, we advise all YAMAHA product owners that any service requiredshould be performed by an authorized YAMAHA Retailer or the appointed service representative.IMPORTANT:The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or recognition of any applicabletechnical capabilities, or establish a principle-agent relationship of any form.The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, and service departments of YAMAHA arecontinually striving to improve YAMAHA products. Modifications are, therefore, inevitable and specifications are subject to change without notice or obligation toretrofit. Should any discrepancy appear to exist, please contact the distributors Service Division.WARNING:Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated by grounding yourself to theground buss in the unit (heavy gauge black wires connect to this buss).IMPORTANT:Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.YST-MS201RadioFans.CN 收音机爱 好者资料库YST-MS201WALLOUTLETEQUIPMENTUNDER TESTAC LEAKAGETESTER OREQUIVALENTINSULATINGTABLE1WARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD.
