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 SI and IC are same as above.

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 10

PART REPLACEMENT AND

ADJUSTMENT PROCEDURES

CAUTIONS BEFORE STARTING PART REPLACEMENT

Electronic parts are susceptible to static electricity and may 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. f they are used improperly,

the screw holes will be easily damaged and the parts can not be fixed.
