l 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).

0 Handling of traverse deck (optical pickup)

1. Do not subject the traverse deck (optical pickup) to static slectncity as it is

extremely sensitive to electrical shock.

2. To protect the laser diode against electrostatic breakdown, short the flexible

board (FFC board) with a clip or similar object.

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.

O 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 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.
80, take care not to let your clothes touch the traverse deck {optical pickup).

Caution when Replacing the Traverse Deck:

FFC board Lens (Do not touch)

Wendie it carefully)

Variable resistor

No. @ (GND) pin (Do ncttum)

No. @ (LD) pin

Wrist strap '
(Anti-static bracelet) /

iron plate or some metals to
conduct electricity

The traverse deck has a short point shorted with solder to protect the laser diode against electrostatic breakdown. Be sure to remove the solder from

the short point hetore making connections.
