I 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 01 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. The short land between the No.4 (LD) and N05 (GND) pins on the
flexible boards (FPC) is shorted with a solder buildup to prevent
damage to the laser diode.

To connect to the PC board, be sure to open by removing the
solder build-up, and finish the work quickly,
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.

- Grounding tor 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 conducive material (sheet) or steel sheet on the area where
the traverse deck (optical pickup) is placed, 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).
