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.

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.1. 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 ohms shuntedby 0.15F.GLeakage current must not exceed 0.5mA.GBe sure to test for leakage with the AC plug in both polarities.本機搭載基板付接合部無鉛付。無鉛種類、修理時下記無鉛使用推奨。 Sn+Ag+Cu （錫+銀+銅） Sn+Cu （錫+銅） Sn+Zn+Bi （錫+亜鉛+）注意：無鉛融点温度通常鉛入比3040程度高、合使用。All of the P.C.B.s installed in this unit and solder joints aresoldered using the lead free solder.Among some types of lead free solder currently available,it is recommended to use one of the following types for therepair work.Sn + Ag + Cu (tin + silver + copper)Sn + Cu (tin + copper)Sn + Zn + Bi (tin + zinc + bismuth)Caution:As the melting point temperature of the lead free solder isabout 30C to 40C (50F to 70F) higher than that of the leadsolder, be sure to use a soldering iron suitable to each solder.About lead free solder / 無鉛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 must beused 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 to readjust, disassemble or repair 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 STANDBY/ON SW is turned to the “ON” position, the laser component will emita beam 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 loaded, 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.RadioFans.CN 收音机爱 好者资料库3CD-S2000CD-S2000Material:SA-CDSemiconductor laser (AlGaInP)CDSemiconductor laser (AlGaAs)Wavelength:SA-CD650 nmCD780 nmWarning for power supplyThe primary side of the power supply carries live mains voltage when the player is connected to the mains even whenthe player is switched off !This primary area is not shielded so it is possible to touch copper tracks and/or components when servicing the player.Service personnel have to take precautions to prevent touching this area or components in this area.Note:The screws on the DVD mechanism may never be touched, removed or re-adjusted.Handle the DVD mechanism with care when the unit has to be exchanged!The DVD mechanism is very sensitive for dropping or giving shocks.Laser Diode PropertiesLaser Output:SA-CD5 mW (max.)CD7 mW (max.)B, G models4CD-S2000CD-S2000I PREVENTION OF ELECTROSTATIC DISCHARGESome semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are calledElectrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transis-tors and semiconductor “chip” components. The following techniques should be used to help reduce the incidence of compo-nent damage caused by electro static discharge (ESD).1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD onyour body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wriststrap, which should be removed for potential 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 asaluminum foil, to prevent electrostatic 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 generate electrical 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. (Mostreplacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or compa-rable conductive material).7. Immediately before removing the protective material from the leads of a replacement ES divice, touch the protective mate-rial to the chassis or circuit 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 brush-ing together of your fabric clothes or lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficientto damage an ES device).Grounding for electrostatic breakdown prevention1. Human body grounding.Use the antistatic wrist strap to discharge the static electricity from your body.2. Work table grounding.Put a conductive material (sheet) or steel sheet on the area where the optical pickup is placed and ground the sheet.Caution:The static electricity of your clothes will not be grounded through the wrist strap. So take care not to let your clothes touch theoptical pickup.1M-ohmsConductive material(sheet) or steel sheetAnti-static wrist strap5CD-S2000CD-S2000I FRONT PANELCD-S2000 (U, C, R, T, K, A, B, G, L, J models)I REAR PANELSCD-S2000 (U, C models)CD-S2000 (R model)6CD-S2000CD-S2000CD-S2000 (T model)CD-S2000 (K model)CD-S2000 (A model)7CD-S2000CD-S2000CD-S2000 (B, G models)CD-S2000 (L model)CD-S2000 (J model)8CD-S2000CD-S2000I Audio Section / 部Frequency Response / 周波数特性SA-CD . 2 Hz to 50 kHz (-3 dB)CD .2 Hz to 20 kHzTotal Harmonic Distortion + Noise (1 kHz) / 高調波歪率 （1 kHz）SA-CD . 0.0017 % or lessCD .0.002 % or lessSignal to Noise Ratio / 信号対雑音比 (IHF-A Network).116 dB or moreDynamic Range / SA-CD .110 dB or moreCD .100 dB or moreOutput Voltage (1 kHz, 0 dB) / 出力電圧 （1 kHz、0 dB）. 2.0 0.3 VI General / 総合Power Supply / 電源電圧U, C models .AC 120 V, 60 HzR, L models .AC 110/120/220/230-240 V, 50/60 HzT model.AC 220 V, 50 HzK model.AC 220 V, 60 HzA model.AC 240 V, 50 HzB, G models .AC 230 V, 50 HzJ model .
