The lase diode in the optical pickup may break down due to
potential difference caused by static electricity of clothes or
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 time as possible.
3. Be careful not to apply excessive stress to the flexible board
(FPC board).
4. Do not turn the variable resistor (Laser power adjustment).
Use the antistatic wrist strap to discharge the static electricity
from your body.
