4.2. 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. 3
)
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. (as shown in
Fig. 4
)
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).
