For these reasons,we advise all YAMAHA product owners that any service required should be performed by an authorizedYAMAHA Retailer or the appointed service representative.IMPORTANT:The presentation or sale of this manual to any individual or firm does not constitute authorization, certification orrecognition of any applicable technical 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, andservice departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitableand specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, pleasecontact the distributors Service Division.WARNING:Static discharges can destroy expensive components. Discharge any static electricity your body may haveaccumulated by grounding yourself to the ground 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.RX-V800/RX-V800RDS/HTR-5280P.O.Box 1, Hamamatsu, JapanRadioFans.CN 收音机爱 好者资料库RX-V800/RX-V800RDS/HTR-52801WALLOUTLETEQUIPMENTUNDER TESTAC LEAKAGETESTER OREQUIVALENTINSULATINGTABLEWARNING: 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 REA-SON WHATSOEVER!Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or exposeeyes to solder/flux vapor!If you come in contact with solder or components located inside the enclosure of this product, wash your hands beforehandling food.I TO SERVICE PERSONNEL1. Critical Components InformationComponents having special characteristics are marked sand must be replaced with parts having specifications equalto those originally installed.2. Leakage Current Measurement (For 120V Models Only)When service has been completed, it is imperative to verifythat all exposed conductive surfaces are properly insulatedfrom supply circuits.GMeter impedance should be equivalent to 1500 ohm shuntedby 0.15F.GLeakage current must not exceed 0.5mA.GBe sure to test for leakage with the AC plug in both polarities.I IMPEDANCE SELECTORTO REDUCE THE RISKOF FIRE OR ELECTRIC SHOCK,DO NOT EXPOSE THIS APPLIANCETO RAIN OR MOISTURE.RISQUE DE CHOCELECTRIQUE NE PAS OUVRIR.WARNINGATTENTIONAC OUTLETSSWITCHEDI20V 60HzI00W MAX.
