7.1 Precautions on optical pickup replacement
The optical pickup can be damaged by static electricity
from your body. Be sure to take static electricity
countermeasures when working around the optical pickup.
(Refer to the related page in this Manual about the
countermeasures.)
1. Do not touch the laser diode, actuator or their
associated parts.
2. Do not use a tester to check the laser diode. (Laser
diode can be damaged easily.)
3. Use an anti-static soldering iron when adding or
removing the laser diode shorting jumper.
4. Solder the land on flexible cable of optical pickup unit.
Caution
• When using the soldering iron without anti-static
feature, short-circuit the flexible cable terminal with a
clip before short-circuiting the land.
• After completing the repair, remove the solder from the
laser diode shorting jumper properly following the
procedures described in this Manual.
