Cautions to Be Taken in Handling the Optical Pickup Unit
The laser diode in the optical pickup unit may be damaged due to electrostatic discharge generating from clothes or human body.
Special care must be taken avoid caution to electrostatic discharge damage when servicing the laser diode.
Special care must be taken avoid caution to electrostatic discharge damage when servicing the laser diode.
1. Do not give a considerable shock to the optical pickup unit as it has an extremely high-precise structure.
2. To prevent the laser diode from the electrostatic discharge damage, the flexible cable of the optical pickup unit removed
2. To prevent the laser diode from the electrostatic discharge damage, the flexible cable of the optical pickup unit removed
should be short-circuited with a short pin or a clip.
3. The flexible cable may be cut off if an excessive force is applied to it. Use caution when handling the flexible cable.

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 electric-
ity in the working environment. Proceed servicing works under the working environment where grounding works is completed.
ity in the working environment. Proceed servicing works under the working environment where grounding works is completed.
3.4.2.1.
Worktable grounding
1. Put a conductive material (sheet) or iron sheet on the area where the optical pickup is placed, and ground the sheet.
