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. 本機搭載基板付使用 下記通。 The P.C.B.s installed in this unit are soldered using the following solder.

Sn + Ag + Cu (tin + silver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth) Caution: 1. 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. 2. If lead solder must be used, be sure to remove lead free solder from each terminal section of the parts to be replaced and from the area around it completely before soldering, or make sure that the lead free solder and lead solder melt together fully. THE COMPACT DISC RECORDER SHOULD NOT BE ADJUSTED OR REPAIRED BY ANYONE EXCEPT PROPERLY QUALIFIED SERVICE PERSONNEL. WARNING: CHEMICAL CONTENT NOTICE! The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and /or plastic (where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm. DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REA- SON WHATSOEVER! 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. RadioFans.CN 收音机爱 好者资料库 CDR-HD1500 3 CDR-HD1500 CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. PROTECTION OF EYES FROM LASER BEAM DURING SERVICING This set employs a laser. Therefore, be sure to carefully follow the instructions below when servicing. 1. Laser Diode Properties Material: GaAlAs Wavelength: 780 to 787 nm Pulse durations and max. output at the objective lens of the laser pickup unit DC erase mode: Max. 12 mW (Continuous) Write mode: Max. 70 mW (Max. Cycle 98 ns, Min. Cycle 27 ns at Max. Speed) 2. When checking the laser diode emission, keep your eyes more than 30 cm away from the objective lens. 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. This device is a Class IIIb laser device. Class IIIb means With the protective case removed, exposure to the light output from the laser, either directly or reflected by a mirror, can cause harm to the eyes, but there is no danger to the eyes from exposure to dispersed reflected laser light. (Generally 0.5 W or less) 2. Always wear eyeglasses designed for protection against laser light. 3. Always wear gloves. 4. Have no reflective objects anywhere near this device. 5. Figure A shows from where in this device the laser is emitted. 6. When switching on the power to the device for the first time, always measure the laser power with a laser power meter and check that the power is no greater than the number of Watts in the specifications. 7. Never look directly at the laser light while the laser is emitting light. 8. Do not allow the laser light to shine directly on your skin while the laser is emitting light.

Fig. A RadioFans.CN 收音机爱 好者资料库 CDR-HD1500 4 CDR-HD1500 I PREVENTION OF ELECTROSTATIC DISCHARGE 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-effect transistors and semiconductor “chip” components. The following techniques should be used to help reduce the incidence of component 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 comparable conductive material). 7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective 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 such as the brushing together of your clothes fabric or the 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 an anti static wrist strap to discharge the static electricity from your body. 2. Work table grounding: Put a grounded conductive material (sheet) or iron sheet on the area where the optical pickup is placed. 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 Conductive material (sheet) or steel sheet Anti-static wrist strap VARO!:AVATTAESSA JA SUOJALUKITUS OHITETTAESSA OLET ALTTIINA N K Y M T T M L L E L A S E R - STEILYLLE.
