SECTION 1

PRECAUTION

1.1 Safety Precautions

!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.

1-6 (No.MA430<Rev.001>)

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 laser products.

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 sheet) 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 installation, both sides of the laser diode on the replacement optical

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) Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit.

(2) Cut off the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific details, refer to the

replacement procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take too long a

time when attaching it to the connector.

(3) Handle the flexible cable carefully as it may break when subjected to strong force.

(4) It is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it.

1.4 Attention when traverse unit is decomposed

*Please refer to "Disassembly method" in the text for the pickup unit.

• Apply solder to the short land before the card wire is disconnected from the connector on the pickup unit.

(If the card wire is disconnected without applying solder, the pickup may be destroyed by static electricity.)

• In the assembly, be sure to remove solder from the short land after connecting the card wire.

1.5 Important for laser products

1.CLASS 1 LASER PRODUCT

2.CAUTION :

(For U.S.A.) Visible and/or invisible class II laser radiation

when open. Do not stare into beam.

(Others) Visible and/or invisible class 1M laser radiation

when open. Do not view directly with optical instruments.

3.CAUTION : Visible and/or invisible laser radiation when

open and inter lock failed or defeated. Avoid direct

exposure to beam.

4.CAUTION : This laser product uses visible and/or invisible

laser radiation and is equipped with safety switches which

prevent emission of radiation when the drawer is open and

the safety interlocks have failed or are defeated. It is

dangerous to defeat the safety switches.

5.CAUTION : If safety switches malfunction, the laser is able

to function.

6.CAUTION : Use of controls, adjustments or performance of

procedures other than those specified here in may result in

hazardous radiation exposure.

REPRODUCTION AND POSITION OF LABELS and PRINT

!Please use enough caution not to

see the beam directly or touch it

in case of an adjustment or operation

check.

3.2 CD MECHANISM assembly section

• Remove the CD MECHANISM assembly from the main body.

3.2.1

Removing the MECHANISM CONTROL BOARD

assembly (See Fig.

and

)

(1)

From the bottom side of CD MECHANISM assembly,

remove the solders from the soldered sections (

and

) on the MECHANISM CONTROL BOARD assembly.

(See Fig.

(2) Remove the three screws Aattaching the MECHANISM

CONTROL BOARD assembly. (See Fig.1.)

(3) Solder the short land sections on the pickup. (See Fig.2.)

Caution:

• Solder the short land sections on the pickup before

disconnecting the flexible wire from the connector

CN102 on the MECHANISM CONTROL BOARD as-

sembly.

If the card wire is disconnected without attaching

solder, the pickup may be destroyed by static

electricity. (See Fig.

•

When attaching the MECHANISM CONTROL

BOARD assembly, remove the solders from the

short land sections after connecting the flexible

wire to the connector CN102 on the MECHANISM

CONTROL BOARD assembly.
