The laser diode in the optical pickup may break down due to
potential difference caused by static electricity of clothes or
human body.
So be careful of electrostatic break down during repair of the
optical pickup.
4.1. Handling of optical pickup
1. Do not subject the optical pickup to static electricity as it is
extremely sensitive to electrical shock.
2. To prevent the breakdown of the laser diode, an antistatic
shorting pin is inserted into the flexible board (FPC Board).
When removing or connecting the short pin, finish the job in
as short times as possible.
3. Be careful not to apply excessive stress to the flexible board
(FPC Board).
1. Human body grounding
Use the antistatic wrist strap to discharge the static
electricity 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 touch the optical pickup.
4. Do not turn the variable resistor (Laser power adjustment).
It has already been adjusted.
8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise hamless 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).
3 PRECAUTION OF LASER DIODE
Caution
This unit utilizes a class I laser. Invisible laser radiation is emitted from the optical pickup lens when the unit is turned on:
1. Do not look directly into the pickup lens.
2. Do not use optical instruments to look at the pickup lens.
3. Do not adjust the preset variable resistor on the optical pickup.
4. Do not disassemble the optical pickup unit.
5. If the optical pickup is replaced, use the manufactures specified replacement pickup only.
6. Use of control or adjustment or performance of procedures other than those specified herin may result in hazardous radiation
exposure.
