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-S1000CD-S1000CAUTION - VISIBLE AND / OR INVISIBLE LASER RADIATION WHEN OPEN.

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-S1000CD-S1000I FRONT PANELCD-S1000 (U, C, R, T, K, A, B, G, L, J models)I REAR PANELSCD-S1000 (U, C models)CD-S1000 (R model)6CD-S1000CD-S1000CD-S1000 (T model)CD-S1000 (K model)CD-S1000 (A model)7CD-S1000CD-S1000CD-S1000 (B, G models)CD-S1000 (L model)CD-S1000 (J model)8CD-S1000CD-S1000I 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 (1 kHz) / 高調波歪率 （1 kHz）.0.002 % or lessSignal to Noise Ratio / 信号対雑音比 (IHF-A Network).113 dB or moreDynamic Range / SA-CD .105 dB or moreCD .100 dB or moreOutput Level (1 kHz, 0 dB) / 出力 （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 .
