General Descriptions

1.  PREPARATION FOR SERVICING

The Pickup Head consists of a laser diode that is very susceptible to external static electricity.

Although it may operate properly after replacement, if subjected to electrostatic discharge during replacement, its

life may be shortened. When replacing the laser diode, LSI's and IC's, use a conductive mat, soldering iron with

ground wire, etc. to protect against damage from static electricity.

1M

Ω

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

Ω
