Burrs formed during molding may be left over on some parts of the chassi

42、s. Therefore, pay attention to such burrs in the case of preforming repair of this system. ! Please use enough caution not to see the beam directly or touch it in case of an adjustment or operation check. 1-8 (No.MA465) 1.2Preventing static electricity Electrostatic discharge (ESD), which occurs whe

43、n static electricity stored in the body, fabric, etc. is discharged, can destroy the laser diode in the traverse unit (optical pickup). 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 optic

44、al pickup (laser diode) in devices such as laser products. Be careful to use proper grounding in the area where repairs are being performed. (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 u

45、nit (optical pickup) on it. (2) Ground yourself Use an anti-static wrist strap to release any static electricity built up in your body. (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 pick

46、up are shorted. After replacement, return the shorted parts to their original condition. (Refer to the text.) Do not use a tester to 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 (opti

47、cal pickup) (1) Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit. (2) Cut off 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. Rem

48、ove the anti-static pin when replacing the traverse unit. Be careful not to take too long a time when attaching it to the connector. (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

49、 power. Do not turn it. 1.4Attention when traverse unit is decomposed *Please refer to Disassembly method in the text for the pickup unit. Apply solder to the short land before the card wire is disconnected from the connector on the pickup unit. (If the card wire is disconnected without applying solder, the pickup may be destroyed by static electricity.) In the assembly, be sure to remove solder from the short land after connecting the card wire. 1M (caption) Anti-static wrist strap Conductive material (conductive sheet) or i
