The laser diode in the traverse unit (optical pickup) may brake
down due to static electricity of 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 Video Recorder 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-circuit. After replacing the
parts with new ones, remove the short circuit according to
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 OPTICAL PICK-UP UNIT
The laser diode in the optical pick-up unit may break down due
to potential difference caused by static electricity of clothes or
human body.
So be careful of electrostatic breakdown during repair of the
optical pick-up unit.
6.2.1.
HANDLING OF OPTICAL PICK-UP
UNIT
1. The optical pick-up unit has high precision extremely
sensitive structure. Be careful not to apply excessive shock.
