LASER BEAM CAUTION LABEL
When the power supply is being turned on, you may not remove this laser beam caution label. If it removes, radiation of a
laser may be received.
PREPARATION OF SERVICING
Pickup Head consists of a laser diode that is very susceptible to external static electricity.
Although it operates properly after replacement, if it was subject to electrostatic discharge during replacement,
its life might be shortened. When replacing, use a conductive mat, soldering iron with ground wire, etc. to
protect the laser diode from damage by static electricity.
And also, the LSI and IC are same as above.
1MΩ
Ground conductive
wrist strap for body.
Soldering iron
with ground wire
or ceramic type
Conductive mat
The ground resistance
between the ground line
and the ground is less than 10Ω.

PART REPLACEMENT AND
ADJUSTMENT PROCEDURES
CAUTIONS BEFORE STARTING PART REPLACEMENT
Electronic parts are susceptible to static electricity and may be easily damaged, so do not forget to ground as required.
Many screws are used inside the unit. To prevent the screws from missing or dropping, etc. always use a magnetized
screwdriver in servicing. Several kinds of screws are used and some of them need special cautions. That is, take care of
the tapping screws securing molded parts and fine pitch screws used to secure metal parts. If they are used improperly,
the screw holes will be easily damaged and the parts can not be fixed.
