Special care must be taken avoid caution to electrostatic discharge damage when servicing the laser dio

21、de. 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 should be short-circuited with a short pin or a clip. 3. The

22、flexible cable may be cut off if an excessive force is applied to it. Use caution when handling the flexible cable. 4. The antistatic FPC is connected to the new optical pickup unit. After replacing the optical pickup unit and connecting the flexible cable, cut off the antistatic FPC. 5.2. Grounding

23、 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. 5.2.1. W

24、orktable grounding 1. Put a conductive material (sheet) or iron sheet on the area where the optical pickup is placed, and ground the sheet. 5.2.2. Human body grounding 1. Use the anti-static wrist strap to discharge the static electricity form your body. 9 SA-HT940P / SA-HT940PC 10 SA-HT940P / SA-HT
