NOTES ON HANDLING THE OPTICAL PICK-UP

BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electro-

static break-down because of the potential 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.

NOTES ON LASER DIODE EMISSION CHECK

Never look into the laser diode emission from right above when

checking it for adjustment. It is feared that you will lose your sight.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK

(LCX-2R)

The laser diode in the optical pick-up block may suffer electro-

static break-down easily. When handling it, perform soldering

bridge to the laser-tap on the flexible board. Also perform mea-

sures against electrostatic break-down sufficiently before the op-

eration. The flexible board is easily damaged and should be handled

with care.
