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.ERROR MESSAGE.1011IC DATA .1216DISPLAY DATA .17BLOCK DIAGRAM.1819PRINTED CIRCUIT BOARD .2023IC BLOCK .2425PIN CONNECTION DIAGRAM.25SCHEMATIC DIAGRAM.26PARTS LIST.2735I CONTENTSTO SERVICE PERSONNEL .12PREVENTION OF ELECTROSTATIC DISCHARGE TOELECTROSTATICALLY SENSITIVE DEVICES .2REAR PANELS.3SPECIFICATIONS.3INTERNAL VIEW .4DISASSEMBLY PROCEDURES .45STANDARD OPERATION CHART.67TEST MODE.89CRX-E200 is composed of RX-E200 andCDX-E200.

Therefore, be sure to carefully followthe 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 your eyesmore than 30 cm away from the objective lens.Critical Components Information.Components having special characteristics are marked Zand must be replaced with parts having specifications equalto those originally installed.I TO SERVICE PERSONNELWARNING: Laser SafetyThis product contains a laser beam component. This component may emit invisible, as well as visible radiation,which may cause eye damage. To protect your eyes and skin from laser radiation, the following precautions mustbe used during servicing of the unit.1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away fromthe laser pick-up unit at all times. Do not stare at the laser beam at any time.2) Do not attempt readjustment, disassembly or repair of the laser pick-up, unless noted elsewhere in this manual.3) CAUTION : Use of controls, adjustments or performance of procedures other than those specified herein may result inhazardous radiation exposure.Laser Emitting conditions:1) When the Top Cover is removed, and the POWER SW is turned to the ON position, the laser component will emit abeam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate through thelens of the laser pick-up unit. Do not attempt any servicing during this period!If no disc is detected, the laser will stop emitting the beam. When a disc is set, you will not be exposed to any laseremissions.2) The laser power level can be adjusted with the VR on the pick-up PWB, however, this level has been set by the factoryprior to shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in thismanual. Adjustment of this control can increase the laser emission level from the device.Optical Pick-upRadioFans.CN 收音机爱 好者资料库CDX-E200CDX-E2002R, B, G modelsR, B, G modelsVARO!: AVATTAESSA JA SUOJALUKITUS OHITETTAESSA OLET ALTTIINA NKYMTTMLLELASER-STEILYLLE.

Such components commonly are called ElectrostaticallySensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor “chip”components. The following techniques should be used to help reduce the incidence of component damage caused by electro static discharge(ESD).1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your body by touchinga known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap, which should be removed forpotential shock reasons prior to applying power to the unit under test.2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to preventelectrostatic charge buildup or exposure of the assembly.3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.4. Use only an anti-static solder removal device. Some solder removal devices not classified as “anti-static (ESD protected)” can generateelectrical charge sufficient to damage ES devices.5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ESdevices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material).7. Immediately before removing the protective material from the leads of a replacement ES divice, touch the protective material to the chassis orcircuit assembly into which the device will be installed.CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together ofyour clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficient to damage an ES device).Grounding for electrostatic breakdown prevention1.Human body grounding.Use the antistatic wrist strap to discharge the staticelectricity from your body.2.Work table grounding.Put a conductive material (sheet) or steel sheet on the areawhere the optical pickup is placed and ground the sheet.Caution:The static electricity of your clothes will not be groundedthrough the wrist strap. So take care not to let your clothestouch the optical pickup.1MConductive material(sheet) or steel sheetAnti-static wrist stripThe lavel is underthe CD mechanism.CDX-E200CDX-E200I REAR PANELS3M R modelM G modelM B modelG DIMENSIONUnit : mm (inch)I SPECIFICATIONSOutput Level1kHz, 0dB2.0 0.5VrmsSignal to Nosie Ratio (EIAJ)102dBDynamic Range95dBHarmonic Distortion+Noise (1kHz)0.004%Frequency Response2Hz 20kHz0.5dBPower RequirementsB, G models230V AC 50HzR model110/120/220/240V AC 50/60HzPower Consumption13WDimensions (W x H x D)217 x 108 x 290mm(8-9/16 x 4-1/4 x 11-7/16)Weight3.0kg (6 lbs 9 oz)FinishGold colorR, G, B modelsSilver colorG, B models*Specifications are subject to change without notice.B .
