SERVICE MANUAL100848IMPORTANT NOTICEThis manual has been provided for the use of authorized YAMAHA Retailers and their service personnel.It has been assumed that basic service procedures inherent to the industry, and more specifically YAMAHA Products, are alreadyknown and understood by the users, and have therefore not been restated.WARNING:Failure to follow appropriate service and safety procedures when servicing this product may result in personalinjury, destruction of expensive components, and failure of the product to perform as specified. 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.P.O.Box 1, Hamamatsu, JapanI CONTENTSTO SERVICE PERSONNEL . 2FRONT PANELS. 34REAR PANELS . 47REMOTE CONTROL PANELS. 7SPECIFICATIONS / 参考仕様 . 811INTERNAL VIEW . 11DISASSEMBLY PROCEDURES / 分解手順 . 1214SELF DIAGNOSIS FUNCTION (DIAG) /自己診断機能（）. 1535CONFIRMATION OF IDLING CURRENT /電流確認 . 36DISPLAY DATA . 3738IC DATA . 3944PRINTED CIRCUIT BOARD . 4553PIN CONNECTION DIAGRAM . 54BLOCK DIAGRAM. 55SCHEMATIC DIAGRAM . 5660PARTS LIST. 6179REMOTE CONTROL. 8081AV RECEIVER/AV AMPLIFIERRX-V340/RX-V340RDS/HTR-5630/HTR-5630RDS/DSP-AX340RX-V340/RX-V340RDS/HTR-5630/HTR-5630RDS/DSP-AX340RadioFans.CN 收音机爱 好者资料库Copyright 2003 YAMAHA CORPORATIONThis manual is copyrighted by YAMAHA and may not be copied or redistributed either in print or electronically without permission.RX-V340/RX-V340RDS/HTR-5630/HTR-5630RDS/DSP-AX340RX-V340/RX-V340RDS/HTR-5630/HTR-5630RDS/DSP-AX3402151 (5-15/16)130 (5-1/8)281 (11-1/16)21(13/16)19(3/4)22(7/8)322 (12-11/16) 435 (17-1/8)Unit : mm (inch)単位: mm（）WALLOUTLETEQUIPMENTUNDER 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 (whereapplicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (andpossibly 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.“CAUTION”“F681: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 5A, 125V FUSE.”CAUTIONF681: REPLACE WITH SAME TYPE 5A, 125V FUSE.ATTENTIONF681: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 5A, 125V.GLeakage current must not exceed 0.5mA.GBe sure to test for leakage with the AC plug in both polarities.
