For thesereasons, we advise all YAMAHA product owners that any service required should be performed by anauthorized YAMAHA Retailer or the appointed service representative.IMPORTANT:The presentation or sale of this manual to any individual or firm does not constitute authorization, certificationor recognition of any applicable technical capabilities, or establish a principle-agent relationship of anyform.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,inevitable and specifications are subject to change without notice or obligation to retrofit. 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 haveaccumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to thisbuss).IMPORTANT:Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to theunit.IMPORTANT NOTICEDSP-AX1/RX-V1SERVICE MANUALRadioFans.CN 收音机爱 好者资料库DSP-AX1/RX-V1DSP-AX1/RX-V1I TO SERVICE PERSONNEL1. Critical Components Information.Components having special characteristics are marked Zand 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.AC LEAKAGETESTER OREQUIVALENTEQUIPMENTUNDER TESTINSULATINGTABLEWALLOUTLET1WARNING: CHEMICALCONTENT NOTICE!The solder used in the production of this productcontains LEAD. In addition, other electrical/electronic and/or plastic (where applicable)components may also contain traces of chemicalsfound by the California Health and WelfareAgency (and possibly other entities) to causecancer and/or birth defects or other reproductiveharm.DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS INYOUR MOUTH FOR ANY REASONWHATSOEVER!Avoid prolonged, unprotected contact betweensolder and your skin!
