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 poten~
tial difference generated by the charged electrostatic
load, etc. on clothing and the human body.

During repair, pay attention to electrostatic break-
down 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.
