19、者资料库 Ra d i o Fa n s .CN 3 ZS-M30 1-1.NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electro- static break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. Duri

20、ng repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. 1-2. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so

21、as to be focused on the disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emis- sion,observe from more than 30 cm away from the objectivelens. 1-3. NOTES ON CHIP COMPONENT REPLACEMENT Never reuse a disconnected chip component. Notice

22、 that the minus side of a tantalum capacitor may be dam- aged by heat. 1-4. FLEXIBLE CIRCUIT BOARD REPAIRING Keep the temperature of the soldering iron around 270 C dur- ing repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to appl

23、y force on the conductor when soldering or unsoldering. SAFETY-RELATED COMPONENT WARNING! COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS S

24、HOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY. 1-6. CHECKING THE LASER DIODE AND FOCUS SEARCH OPERATION 1. Turn on the POWER and open the CD cover. 2. As shown below, push S701 (CD DOOR) with a screwdriver or other tool. 3. Press the CD button. 4. Check the objective lens to make sure that

25、 the laser diode is emitting light. If not so, the auto power control circuit or optical pickup would be damaged. Verify that the objective lens moves vertically three times for focus search. This Compact Disc player is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT label is locate

26、d on the bottom exterior. CAUTION Use of controls or adjustments or performance of proce- duresother than those specified herein may result in haz- ardous radiation exposure. 1-5. CHUCK PLATE JIG ON REPAIRING On repairing CD section, playing a disc without the CD lid, use Chuck Plate Jig. Code numbe
