5. PREVENTION OF STATIC ELECTRICITY DISCHARGE
The laser diode in the traverse unit (optical pickup) may brake down due to static electricity of clothes
or human body. Use due caution to electrostatic breakdown when servicing and handling the laser
diode.
5.1. Grounding for electrostatic breakdown prevention
Some devices such as the DVD player use the optical pickup (laser diode) and the optical pickup will be
damaged by static electricity in the working environment. Proceed servicing works under the working
environment where grounding works is completed.
5.1.1. Worktable grounding
1. Put a conductive material (sheet) or iron sheet on the area where the
optical pickup is placed, and ground the sheet.
5.1.2. Human body grounding
1. Use the anti-static wrist strap to discharge the static electricity form
your body.
5.1.3. Handling of optical pickup
1. To keep the good quality of the optical pickup maintenance parts
during transportation and before installation, the both ends of the laser
diode are short-circuited. After replacing the parts with new ones,
