Cautions to Be Taken in Handling the Optical Pickup Unit The laser diode in the optical pickup unit may be damaged due to electrostatic dis

44、charge 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 extremely high-precise structure. 2. To prevent the laser diode from th

45、e 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 FPC is connected

46、to the new optical pickup unit. After replacing the optical pickup unit and connecting the flexible cable, cut off the antistatic FPC. 10.2. Grounding for electrostatic breakdown prevention Some devices such as the DVD player use the optical pickup (laser diode) and the optical pickup will be damage

47、d by static electricity in the working environment. Proceed servicing works under the working environment where grounding works is completed. 10.2.1. Worktable grounding 1. Put a conductive material (sheet) or iron sheet on the area where the optical pickup is placed, and ground the sheet. 10.2.2. H

48、uman body grounding 1. Use the anti-static wrist strap to discharge the static electricity form your body. 16 SA-HT930EE 17 SA-HT930EE Some chassis components may have sharp edges.
