- 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.
4. Do not turn the variable resistor (laser power adjustment). It has
already been adjusted.
- Grounding for electrostatic breakdown prevention
1. Human body grounding
Use the anti-static 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 traverse deck (optical pickup) is place, 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
traverse deck (optical pickup).
on when replacing the Traverse Deck
The traverse deck has a short point shorted with solder to protect the laser diode against
electrostatics breakdown. Be sure to remove the solder from the short point before making
connections.
