NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer
electrostatic breakdown because of the potential differ-
ence 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 care.

laser diode emission, observe more than 30 cm away from
the objective lens.
