NOTES ON HANDLING THE OPTICAL PICK-UP
The laser diode may suffer electrostatic breakdown because of the
potential difference generated by the charged electrostatic load, etc.
on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also use
the procedure in the printed matter which is included in the repair
parts.
The flexible board is easily damaged and should be handled with

PRECAUTION FOR CHECKING EMISSION OF
LASER DIODE
LASER DIODE
Laser light of the equipment is focused by the object lens in the
optical pick-up so that the light focuses on the reflection surface of
the disc. Therefore, be sure to keep your eyes more then 30 cm
apart from the object lens when you check the emission of laser
diode.
