Cautions to be taken during replacement of optical pickup

Optical pickup could be damaged due to the static electricity discharged from human body. Wear proper protection gear against
static electricity during optical pickup and its peripheral repair. (Refer to the section regarding protection against static electricity.)
1. Do not touch laser diode, actuator and their peripherals.
2. Do not check laser diode with a tester and such. (The tester will be destroyed.)
3. For short-circuiting or removing laser diode, the use of an anti-static soldering iron is recommended.
(Recommended model: HAKKO ESD product)
4. Solder the land of the flexible cable in the optical pickup.
Note:
· If an anti-static soldering iron is not available, short-circuit the terminal surface of the flexible cable and then the land using
a clip or equivalent device.
· For short-circuit of the above laser diode, remove soldering as instructed in this manual after completing repair.
