18、Unit The laser diode in the optical pickup unit may break down due to static electricity of clothes or human body. Special care must be taken avoid caution to electrostatic breakdown when servicing and handling the laser diode. 5.1. Cautions to Be Taken in Handling the Optical Pickup Unit The laser

19、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. 1. Do not give a considerable shock to the optical pickup unit as it has an

20、 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 flexible cable may be cut off if an excessive force is applied to it. Use cauti

21、on 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 for electrostatic breakdown prevention Some devices such as the DVD player use

22、 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. Worktable grounding 1. Put a conductive material (sheet) or iron sheet on the ar

23、ea 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-HT640WPL 10 SA-HT640WPL Remote control AM loop antenna FM indoor antenna Video Cable AC cord Digital transceiver* Speak
