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, remove the short circuit according to the correct procedure.
(See this Technical Guide.)
2. Do not use a tester to check the laser diode for the optical pickup.
Failure to do so will damage the laser diode due to the power
supply in the tester.
