3.2. Grounding for electrostatic breakdown prevention
1. Human body grounding
Use the anti-static wrist strap to discharge the static electricity
from your body. (As shown in
Fig. 2 .)
2. Work table grounding
Put a conductive material (sheet) or steel sheet on the area where
the 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).
