SECTION 1

PRECAUTIONS

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.

1-8 (No.MA248)

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 DVD players.

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 DVD pickup unit.

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

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

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

1.5 Important for laser products

1.CLASS 1 LASER PRODUCT

2.DANGER : Invisible laser radiation when open and inter

lock failed or defeated. Avoid direct exposure to beam.

3.CAUTION : There are no serviceable parts inside the

Laser Unit. Do not disassemble the Laser Unit. Replace

the complete Laser Unit if it malfunctions.

4.CAUTION : The CD,MD and DVD player uses 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

Please use enough caution not to

see the beam directly or touch it

in case of an adjustment or operation

check.

WARNING LABEL

CAUTION : Visible and Invisible

laser radiation when open and

interlock failed or defeated.

AVOID DIRECT EXPOSURE TO

BEAM. (e)

VARNING : Synlig och

den öppnas och spärren är

urkopplad. Betrakta ej

strålen. (s)

VARO : Avattaessa ja suojalukitus

ohitettuna tai viallisena olet alttiina

näkyvälle ja näkymättömälle

lasersäteilylle. Vältä säteen

kohdistumista suoraan itseesi. (f)

ADVARSEL : Synlig og usynlig

åben eller interlocken fejeler.

Undgå direkte eksponering til

stråling. (d)
