Therefore, pay attention to such burrs in the case of preforming repair of this system. ! Please use enough caution not to s

30、ee the beam directly or touch it in case of an adjustment or operation check. (No.MA293)1-7 1.2Preventing static electricity Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser diode in the traverse unit (optical p

31、ickup). Take care to prevent this when performing repairs. 1.2.1 Grounding to prevent damage by static electricity Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as CD players. Be careful to use proper grounding in the area where repairs are being pe

32、rformed. (1) Ground the workbench Ground the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before placing the traverse unit (optical pickup) on it. (2) Ground yourself Use an anti-static wrist strap to release any static electricity built up in your bo

33、dy. (3) Handling the optical pickup In order to maintain quality during transport and before installation, both sides of the laser diode on the replacement optical pickup are shorted. After replacement, return the shorted parts to their original condition. (Refer to the text.) Do not use a tester to

34、 check the condition of the laser diode in the optical pickup. The testers internal power source can easily destroy the laser diode. 1.3Handling the traverse unit (optical pickup) (1) Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit. (2) Cut off

35、the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific details, refer to the replacement procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take too long a time when attaching it to the connector.

36、 (3) Handle the flexible cable carefully as it may break when subjected to strong force. (4) It is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it. 1.4Attention when traverse unit is decomposed *Please refer to Disassembly method in the text for the CD pic

37、kup unit. Apply solder to the short land before the flexible wire is disconnected from the connector on the CD pickup unit. (If the flexible wire is disconnected without applying solder, the CD pickup may be destroyed by static electricity.) In the assembly, be sure to remove solder from the short l

38、and after connecting the flexible wire. 1M (caption) Anti-static wrist strap Conductive material (conductive sheet) or iron plate Wires Push switch Pickup Base board Pickup Connector Flexible wire Frame CD mechanism assembly 1-8 (No.MA293) 1.5Important for laser products REPRODUCTION AND POSITION OF
