1.1 Safety Precautions
SECTION 1
PRECAUTION
!
!
Burrs formed during molding may be left over on some parts of the chassis. Therefore,
pay attention to such burrs in the case of preforming repair of this system.
Please use enough caution not to see the beam directly or touch it in case of an
adjustment or operation check.
(No.49879)1-3
1.2 Preventing static electricity
Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser
diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs.
1.2.1 Grounding to prevent damage by static electricity
Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as mechanism unit.
Be careful to use proper grounding in the area where repairs are being performed.
(1) Ground the workbench
Ground the workbench by laying conductive material (such as a conductive sh eet) or an iron plate over it before placing the
traverse unit (optical pickup) on it.
(2) Ground yourself
Use an anti-static wrist strap to release any static electricity built up in your body.

(3) Handling the optical pickup
• In order to maintain quality during transport and before instal lation, both sides of the laser di ode on the replacement optica l
pickup are shorted. After replacement, return the shorted parts to their original condition.
(Refer to the text.)
• Do not use a tester to check the condition of the laser diode in the optical pickup. The tester's internal power source can easily
destroy the laser diode.
1.3 Handling the traverse unit (optical pickup)
(1) Before disconnecting the flexible wire from the connector CN10
ible wire.
Caution:
If you do not follow this instruction, the DVD pickup may be damaged.
(2) Disconnect the flexible wire from the connector CN10
on the front end board.
(3) Remove the solders from the short-circuit point on the flexible wire after replacing the DVD pickup.
(4) Connect the flexible wire to the connector CN10
