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 electricity 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.

I Grounding for electrostatic breakdown prevention
1. Human body grounding

Use the and-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).

Caution when Replacing the Traverse Deck:

FFC board Lens (Do not touch)

i(Handle it carefully)

Variable resistor
(Do not turn)

Wrist strap
(Anti-static bracelet) /

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 before making connections.

I Precaution of Laser Diode

CAUTION:
Wave length: 780 nm

This product utilizes a laser diode with the unit turned on", invisible laser radiation is emitted from the pick up lens.

Maximum output radiation power from pick up: 100 MWNDE
Laser radiation from the pick up unit is safety level, but be sure the followings:

1. Do not disassemble the pick up unit, since radiation from exposed laser diodeiis dangerous.
2. Do not adjust the variable resistor on the pick up unit. it was already adjusted.

3. Do not look at the focus lens usingioptical instruments.

4. Recommend not to look at pick up lens for a long time.
