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.
4. The antistatic FFC is connected to the new optical pickup unit. After replacing the optical pickup unit and connecting the flexi-
ble cable, cut off the antistatic FFC.

Grounding for electrostatic breakdown prevention
Some devices such as the CD 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.
2.4.2.1.
Worktable grounding
1. Put a conductive material (sheet) or iron sheet on the area where the optical pickup is placed, and ground the sheet.
2.4.2.2.
Human body grounding
1. Use the anti-static wrist strap to discharge the static electricity form your body.
