Precautions for Laser Diode Emission Check
When checking the emission of the laser diode during adjust-
ments, never view directly downwards as this may lead to
blindness.
Precautions for Using Optical Pick-up
As the laser diode inside the optical pick-up damages by static
electricity easily, solder the laser tap of the Optical pick-up
flexible board when handling. Also take the necessary measures
to prevent damages by static electricity. Handle the Optical pick-
up flexible board with care as it breaks easily.
