2. Handling Precautions for Traverse Deck
The laser diode in the traverse deck (optical pickup) may break down due to potential difference
caused by static electricity of clothes or human body.
So be careful of electrostatic breakdown during repair of the traverse deck (optical pickup).
2.1. Handling of traverse deck (optical pickup)
1. Do not subject the traverse deck (optical pickup) to static electricity as
it is extremely sensitive to electrical shock.
2. To prevent the breakdown of the laser diode, an anti-static shorting
pin is inserted into the flexible board (FFC board). When removing or
connecting the shorting pin, finish the job in as short time as possible.
Refer to
Fig. 2-1.
3. Take care not to apply excessive stress to the flexible board (FFC
board).
4. Do not turn the variable resistor (laser power adjustment). It has
already been adjusted.
