3 Precaution of laser diode
CAUTION:
This unit utilizes a class 1 laser diode in the optical pickup unit .
Invisible laser radiation is emitted from the optical pickup lens.
Wavelength: 780nm
When the unit is turned on:
1. Do not look directly into the optical pickup lens.
2. Do not use optical instruments to look at the optical pickup lens.
3. Do not adjust the preset variable resistor on the optical pickup lens.
4. Do not disassemble the optical optical pickup unit.
5. If the optical pickup is replaced, use the manufacturer’s specified replacement pickup only.
6. Use of control or adjustments or performance of procedures other than those specified herein may result in hazardous radiation
exposure.
CAUTION!
THIS PRODUCT UTILIZES A LASER.
USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT
IN HAZARDOUS RADIATION EXPOSURE.

4 Handling Precautions For Traverse Unit
The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by the static electricity of
clothes or our human body.
So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup).
·
Way of handling the 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). (Fig. 1)
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. (Fig. 2)
Use the anti-static wrist strap to discharge the static electricity from your body.
2. Work table grounding. (Fig. 2)
Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is place, and ground the
sheet.
