When the power supply is being turned on, you may not remove this laser cautions label. If it removes, radiation of laser
may be received.
2.1 ESD PROTECTION
PREPARATION OF SERVICING
Pickup Head consists of a laser diode that is very susceptible to external static electrocity.
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 form damage by static electricity.
And also, the LSI and IC are same as above.
Soldering iron
with ground wire
or ceramic type
Ground conductive
wrist strap for body.
Conductive mat
The ground resistance
between the ground line
and the ground is less than 10
