1-2 Electrostatic Protection Measures
Semiconductor components can be damaged by static electricity charged on clothes, human
body, etc. Take great care when handling components to avoid electrostatic damage, and perform
servicing in an environment where grounding is complete.
(1) Grounding work bench
Lay out an antistatic mat on work bench, and then use the ground plate to ground the work bench.
1-3 Cautions When Handling BD or DVD Drive
The optical pickup in BD or DVD drive has a high precision
structure: Be sure to observe the following cautions.
1) Do not subject optical pickups to any severe vibrations or
impact during movement, installation or disassembly.
2) When performing repair work, do not perform disassembly
any further than that described in this manual.
3) Never turn the semi-variable resistors for adjustment in
optical pickup or BD or DVD drive.
4) NEVER look into the objective lens in optical pickup or
directly view the laser light: You could lose your eyesight.
(2) Grounding human body
Use an antistatic wrist strap to discharge any static electricity charged on the body. Also, use a
tester for wrist strap to make sure that the wrist strap is working normally. Note, however, that
static electricity charged on clothes will not be discharged by wrist strap: Therefore do not allow
your clothes to touch the semiconductor components.
