Cautions to be taken when replacing the optical pickup
The optical pickup may break down due to the static electricity of human body. Take proper
protection measures against static electricity before repairing the parts around the optical
pickup. (See the page describing the PREVENTION OF STATIC ELECTRICITYDISCHARGE.)
1. Do not touch the areas around the laser diode and actuator.
2. Do not judge the laser diode with a tester. (The tester will be
damaged easily.)
3. It is recommended to use a destaticized soldering iron for short-
circuiting or removing the laser diode. (Recommended soldering
