Modifications are, therefore, inevitable and specifi cations are subject to change without notice or obligation to retrofi t. Should

6、 any discrepancy appear to exist, please contact the distributors Service Division. WARNING: Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to th

7、is buss). IMPORTANT: Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.

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

12、Information Components having special characteristics are marked 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 su

13、rfaces are properly insulated from supply circuits. Meter impedance should be equivalent to 1500 ohms shunted by 0.15 F. 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

14、 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

15、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 polarities.

16、older 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 test

17、ing and/or repairing any component within the product, keep your eyes and skin more than 30 cm/1 feet 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 manu

18、al. 3) CAUTION: Use of controls, adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. RadioFans.CN 收音机爱 好者资料库 3 CD-C600 CD-C600 Laser Emitting conditions: 1) When the Top Cover is removed, and the STANDBY/ON SW is turned to the “ON” p

19、osition, 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 b

20、eam. 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 provid

21、ed elsewhere in this manual. Adjustment of this control can increase the laser emission level from the device. Type: GaAlAs Wavelength: 790 nm Laser output: max. 1.23 W * * This output is the value measured at a distance of about 200 mm from the objective lens surface on the Optical Pick-up Block. L

22、aser Diode Properties 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 accidentally touch copper tracks and/or components when servicing the player.

23、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 dropp

24、ing or giving shocks. Warning for power supply 4 CD-C600 CD-C600 Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-e

25、ffect transistors and semiconductor “chip” components. The following techniques should be used to help reduce the incidence of component damage caused by electrostatic discharge (ESD). 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on

26、 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, pla

27、ce 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

28、 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 bef

29、ore you are ready to install it. (Most replacement ES devices 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 device, touch the protec

30、tive material 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 s

31、uch as brushing 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 ele

32、ctricity 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 t

33、ouch the optical pickup.
