For these reasons, we advise all YAMAHA productowners that any service required should be performed by an authorized YAMAHARetailer or the appointed service representative.IMPORTANT:The presentation or sale of this manual to any individual of firm does not constituteauthorization, certification or recognition 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, and service departments of YAMAHA are continually striving to improve YAMAHA products.Modifications are, therefore, inevitable and specifications are subject to change without notice or obligationto retrofit. Should any discrepancy appear to exist, please contact the distributors Service Division.WARNING:Static discharges can destroy expensive components. Discharge any static electricityyour body may have accumulated 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 beforeyou apply power to the unit.RadioFans.CN 收音机爱 好者资料库1RX-V10MK22222I TO SERVICE PERSONNEL1. Critical Components information.Components having special characteristics are marked andmust be replaced with parts having specifications equal tothose originally installed.2. Leakage Current Measurement (For 120V Model only).When service has been completed, it is imperative that youverify that all exposed conductive surfaces are properly insu-lated from 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.WARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (whereapplicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possiblyother 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 REASONWHATSOEVER!Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyesto solder/flux vapor!If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handlingfood.WALLOUTLETEQUIPMENTUNDER TESTAC LEAKAGETESTER OREQUIVALENTINSULATINGTABLEI REMOTE CONTROL PANELRadioFans.CN 收音机爱 好者资料库2RX-V10MK22222M R modelM B ,G modelsI FRONT PANELSSPEAKERSSPEAKERSRDS MODE/FREQEONPTY SEEKMODESTART3RX-V10MK22222M R modelM B modelM G modelI REAR PANELSFMANTINOUTMONITOROUTINOUTSUBWOOFERCENTERMAINSURROUNDREARCENTERREARSUBWOOFERAUDIO SIGNALVIDEOSIGNAL6CH DISCRT INPUT8MIN./SPEAKERSPEAKERS8 MIN./SPEAKERMAININOUTOUT100W MAX.
