Worktable groundingPut a grounded conductive material (sheet) or iron sheet on the area where the optical pickup is placed.2. Human body groundingUse an anti-static wrist strap

31、 to discharge the static electricity from your body.2. Handling of the optical pickup1. To prevent damage to the optical pickup replacement parts during transportation and before installation, both endsof the laser diode are short-circuited. After installing the new part, remove the short circuit ac

32、cording to the correctprocedure in this service manual.2. Do not use a tester to check the laser diode in the optical pickup. The power supply in the tester will damage thelaser diode.3. Handling Precautions for the Traverse Unit (Optical Pickup)1. Handle the traverse unit (optical pickup) gently, a
