This product contains chemicals known to the State of California to cause cancer, or birth defects or other reproductive harm. DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHAT SO EVER! Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder 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 your hands before handling food. 1. Critical Components Information Components having special characteristics are marked s and must be replaced with parts having specifications equal to those originally installed. 2. Leakage Current Measurement (For 120V Models Only) When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits. GMeter impedance should be equivalent to 1500 ohms shunted by 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 are soldered 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 the repair 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 is about 30C to 40C (50F to 70F) higher than that of the lead solder, be sure to use a soldering iron suitable to each solder. About lead free solder / 無鉛 I TO SERVICE PERSONNEL WARNING: Laser Safety This 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 be 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 from the 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 in hazardous 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 emit a beam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate through the lens 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 laser emissions. 2) The laser power level can be adjusted with the VR on the pick-up PWB, however, this level has been set by the factory prior to shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in this manual. Adjustment of this control can increase the laser emission level from the device. 3 CD-S2000 CD-S2000 Material: SA-CDSemiconductor laser (AlGaInP) CDSemiconductor laser (AlGaAs) Wavelength: SA-CD650 nm CD780 nm Warning for power supply The primary side of the power supply carries live mains voltage when the player is connected to the mains even when the 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 Properties Laser Output: SA-CD5 mW (max.)

Such components commonly are called Electrostatically 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 on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap, 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 as aluminum 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. (Most replacement 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) sufficient to damage an ES device). Grounding for electrostatic breakdown prevention 1. 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 the optical pickup. 1M-ohms Conductive material (sheet) or steel sheet Anti-static wrist strap 5 CD-S2000 CD-S2000 I FRONT PANEL CD-S2000 (U, C, R, T, K, A, B, G, L, J models) I REAR PANELS CD-S2000 (U, C models) CD-S2000 (R model) 6 CD-S2000 CD-S2000 CD-S2000 (T model) CD-S2000 (K model) CD-S2000 (A model) 7 CD-S2000 CD-S2000 CD-S2000 (B, G models) CD-S2000 (L model) CD-S2000 (J model) 8 CD-S2000 CD-S2000 I Audio Section / 部 Frequency Response / 周波数特性 SA-CD . 2 Hz to 50 kHz (-3 dB) CD .2 Hz to 20 kHz Total Harmonic Distortion + Noise (1 kHz) / 高調波歪率 （1 kHz） SA-CD . 0.0017 % or less CD .0.002 % or less Signal to Noise Ratio / 信号対雑音比 (IHF-A Network) .116 dB or more Dynamic Range / SA-CD .110 dB or more CD .100 dB or more Output Voltage (1 kHz, 0 dB) / 出力電圧 （1 kHz、0 dB） . 2.0 0.3 V I General / 総合 Power Supply / 電源電圧 U, C models .AC 120 V, 60 Hz R, L models .AC 110/120/220/230-240 V, 50/60 Hz T model.AC 220 V, 50 Hz K model.AC 220 V, 60 Hz A model.AC 240 V, 50 Hz B, G models .AC 230 V, 50 Hz J model .
