Sn + Ag + Cu (tin + silver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth) Caution: As t

14、he 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. TO SERVICE PERSONNEL Leakage current must not exceed 0.5mA. Be sure to test for leakage with the AC plug in both polari-

16、ell as visible radi- ation, which may cause eye damage. To protect your eyes and skin from laser radiation, the following pre- cautions 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/1 feet away fr

17、om 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 perform- ance of procedures other than those specified herein

18、 may result in hazardous radiation exposure. 本機光線放射部品搭載。 部品放射光線目損傷起 。光線目及肌保護、 本機修理作業中下記注意厳守。 1） 時修理時、目及肌光 30 cm 以上離。場合 光線見。 2） 光再調整及分解 。 3） 上指定以外制御、 調整、 手順光線照射結果招恐 。 警告：安全対策 Laser Emitting conditions: 1) When the Top Cover is removed, and the STANDBY/ ON SW is turned to the “ON” position, the laser

19、com- ponent will emit a beam for several seconds to de- tect 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 dis

20、c is loaded, you will not be ex- posed 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

21、in this manual. Adjustment of this control can increase the laser emission level from the device. 1） 取外 STANDBY/ON ON 、検知 5 10 秒間、光 光線放射。間、 修理。 検知、光線放射 停止。場合、 遮光線修理担当者届 。 2） 光基板上 VR 調整可能、工場出荷前調整済 、 VR 廻。 VR 廻 装置光線放射上恐 。 放射条件 Material: GaAlAs Wavelength: 790 nm Laser Output: max. 1.23 W * * This outp

23、en when the player is switched off ! This primary area is not shielded so it is possible to accidentally 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 m

24、echanism 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. Warning for power supply 5 CD-S700 CD-S700 Some semiconductor (solid state) devices can be damaged easily by

25、 static electricity. Such components commonly are called Electrostatically Sensitive (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 com

26、ponent 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,

27、 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 assembl

28、y. 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 protect- ed)” can generate electrical charge sufficient to damage ES devices. 5. Do not use freon-propelled

29、 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 conducti

30、ve 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 or circuit assembly into which the device will be installed. CAUTION: Be sure no power is applied

31、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 brushing together of your fabric clothes or lifting of your foot from a carpeted floor can generate static electricity (

32、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 optica

33、l 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. PREVENTION OF ELECTROSTATIC DISCHARGE 1M-ohms Conductive material (sheet) or steel sheet Anti-static w
