4. 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).
- 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 antistatic shorting pin
is inserted into the flexible board (FFC board).
3. Take care not to apply excessive stress to the flexible board (FFC
board). When removing or connecting the short pin, finish the job in as
short time as possible. (Fig 4.1)
4. Do not turn the variable resistor (laser power adjustment). It has
already been adjusted.
- Grounding for electrostatic breakdown prevention
1. Work table grounding. (Fig 4.2) / Use the anti-static wrist strap to
discharge the static electricity from your body.
