clothes or human body. Use due caution to electrostatic breakdown when servicing and
handling the laser diode.
6.1. 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 electricity in the working environment. Proceed servicing
works under the working environment where grounding works is completed.
6.1.1. Worktable grounding
1. Put a conductive material (sheet) or iron sheet on the area where
the optical pickup is placed, and ground the sheet.
6.1.2. Human body grounding
1. Use the anti-static wrist strap to discharge the static electricity
form your body.
6.1.3. Handling of optical pickup
1. To keep the good quality of the optical pickup maintenance parts
during transportation and before installation, the both ends of the
laser diode are short-circuited. After replacing the parts with new
ones, remove the short circuit accordingto the correct procedure.
(See this Technical Guide.)
2. Do not use a tester to check the laser diode for the optical pickup.
Failure to do so will damage the laser diode due to the power
supply in the tester.
6.2. Handling Precautions for Traverse Unit (Optical Pickup)
1. Do not give a considerable shock to the traverse unit (optical
pickup) as it has an extremely high-precise structure.
2. When replacing the optical pickup, install the flexible cable and
cut its short land with a nipper. See the optical pickup
replacement procedure in this Technical Guide. Before replacing
the traverse unit, remove the short pin for preventingstatic
electricity and install a new unit. Connect the connector as short
