CDX-E100CDX-E100100685SERVICE MANUALCDX-E100IMPORTANT NOTICEThis manual has been provided for the use of authorized YAMAHA Retailers and their service personnel.It has been assumed that basic service procedures inherant 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 all 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, please contactthe distributors Service Division.WARNING:Static discharges can destroy expensive components. Discharge any static electricity your body may have accumu-lated 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 parts replacement. Recheck all work before you apply power to the unit.IC DATA .1216DISPLAY DATA .17IC BLOCK .1819PIN CONNECTION DIAGRAM.19BLOCK DIAGRAM.2021PRINTED CIRCUIT BOARD .2227SCHEMATIC DIAGRAM.28PARTS LIST.2937I CONTENTSTO SERVICE PERSONNEL .12REAR PANELS.3SPECIFICATIONS.3INTERNAL VIEW .4DISASSEMBLY PROCEDURES .45STANDARD OPERATION CHART.67TEST MODE.89ERROR MESSAGE.1011CRX-E100 is composed of RX-E100 andCDX-E100.

Therefore, be sure to carefullyfollow the instructions below when servicing .1. Laser Diode PropertiesGMaterial: GaAlAsGWavelength: 780 nmGEmission Duration : ContinuousGLaser Output: max. 44.6 W* This output is the value measured at a distance ofabout 200 mm from the objective lens surface onthe Optical Pick-up Block.2. When checking the laser diode emission, keep youreyes more than 30 cm away from the objective lens.WARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD. In addition, other electrical/electronicand/or plastic (where applicable) components may also contain traces of chemicals found by theCalifornia Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defectsor other reproductive harm.DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTHFOR ANY REASON WHATSOEVER!Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhalesolder fumes or expose eyes to solder/flux vapor!If you come in contact with solder or components located inside the enclosure of this product, wash yourhands before handling food.1. 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.GBe sure to test for leakage with the AC plug in bothpolarities.I TO SERVICE PERSONNELRadioFans.CN 收音机爱 好者资料库CDX-E100CDX-E1002 R, B, G models R, B, G modelsCLASS 1 LASER PRODUCTEnglishTHIS PRINTING (SEE POSITION SHOWN IN THE ILLUSTRATION) INFORMS THE USER THAT THE APPARATUSCONTAINS A LASER COMPONENT.THIS LABEL (SEE POSITION SHOWN IN THE ILLUSTRATION) WARNS THAT ANY FURTHER PROCEDURE WILLBRING THE USER INTO EXPOSURE WITH THE LASER BEAM.CAUTION : USE OF CONTROLS, ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSESPECIFIED HEREIN, MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.SwedishDENNA MRKNING (SE FIGUR) UPPLYSER OM ATT DET I APPARATEN INGR EN LASERKOMPONENT AV TYPKLASS 1.VARNINGSMRKNING (SE FIGUR) FR STRLNING.
