2 Precaution of Laser Diode

Caution:

This product utilizes a class 1 laser. Invisible laser radiation is emitted from the optical pick-up lens when the unit is turned on:

1. Do not look directly into the pick-up lens.

SL-SW967VP / SL-SW96 7VPC

2. Do not use optical instruments to look at the pick-up lens.

3. Do not adjust the preset variable resister on the optical pick-up.

4. Do not disassemble the optical pick-up unit.

5. If the optical pick-up is replaced, use the manufacture’s specified replacement pick-up only.

6. Use of control or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

3 Handling Precautions for Traverse Deck

The laser diode in the traverse deck (optical pick-up) 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 pick-up).

3.1. Handling of traverse deck (optical pick-up)

1. Do not subject the optical pick-up to static electricity as it is

extremely sensitive to electrical shock.

2. To protect the laser diode against electrostatic breakdown,

be sure that the short land of the flexible board (FFC board) should be short-circuit by solder before pulling out the FFC. Then inserting a short pin or similar object into the tipoftheflexible board. (Refer to Fig. 3-1. )

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. (Refer to Fig. 3-1. )

3.2. Caution when replacing traverse deck

The new traverse deck short-circuits by the short pin, the foil (B) and short lands to protect the laser diode against electrostatic breakdown. Be sure to replace to new one following procedures.

1. Remove the short pin from the FFC, and then connect it to

the connector.

2. Cut the foil (B). (Refer to Fig. 3-1. ) (Take care not to make

contact with cutting point each other.)

3. Unsolder the short lands. (Refer to Fig. 3-1. )

3.3. Grounding for electrostatic breakdown prevention

3.3.1. Human body grounding

Use the anti-static wrist strap to discharge the static electricity from your body. (Refer to Fig. 3-2. )

Fig. 3-1.

Fig. 3-2.

3.3.2. Work table grounding

Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pick-up) is placed, and ground the sheet. (Refer to Fig. 3-3. )

Fig. 3-3.

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 pick-up).
