Assembling and Disassembling the Opti-
cal Pickup
The optical pickup can be damaged by static electricity
from your body.
Be sure to take static electricity countermeasures when
working around the optical pickup.
Handling the Optical Pickup
1. The optical pickup is an extremely high-precision mecha-
nism. Do not subject it to strong damage.
2. Testers cannot be used to check the laser diode of the
optical pickup. The power supply in side the tester can
easily damage the laser diode.
3. Take care when handling the flexible cable because
excessive force can cause it to break.
4. To preserve the quality of the optical pickup replacement
parts during transport and installation, the terminals of the
laser diode are short-circuited. After replacing the parts,
use the proper procedure to return the laser diode to its
original condition.
Static Electricity Countermeasures
The laser diode inside the traverse unit (optical pickup )
can be damaged by static electricity from your body. Be
sure to take static electricity countermeasures when work-
ing around the optical pickup.
Static Electricity Countermeasure Methods
1. Ground yourself
Use an anti-static wrist strap to discharge static electricity
from your body.
2. Ground the workbench
Lay a conductive material (sheet) or steel sheet on the
surface where the traverse unit (optical pickup)is to be
placed, then ground the sheet.
Assembling the Optical Pickup
1. Insert a flexible cable in the arrow direction in the drawing.
2. Cut the flexible cable.
