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 conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is place, 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
The traverse deck has a short point shorted with solder to protect the laser diode against electrostatics breakdown. Be sure to
remove the solder from the short point before making connections.
7 Precaution of Laser Diode
CAUTION:
This unit utilizes a class 1 laser.
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 pick up lens.
2. Do not use optical instruments to look at the pick up lens.
3. Do not adjust the preset variable resistor on the pickup lens.
4. Do not disassemble the optical pick up unit.
5. If the optical pick up is replaced, use the manufacturer’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.
CAUTION!
THIS PRODUCT UTILIZES A LASER.USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN
THOSE SPECIFIED HEREIN
