Precaution Of Laser Diode - Panasonic SA-AK18 Service Manual

• 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 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 :
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.
