4. Handling Precautions ForTraverse Deck

Thelaserdiodeinthetraverse deck (optical pickup)may break downduetopotential difference

causedbystaticelectricityofclothes or humanbody.

So, becareful ofelectrostaticbreakdownduring repairofthetraverse deck (optical pickup).

-Handling oftraverse deck (optical pickup)

1. Donotsubject thetraverse deck (optical pickup)tostatic

electricityas itisextremelysensitivetoelectrical shock.

2. Theshortland betweentheNo.4(LD)and No.5(GND)pinson the

flexibleboard(FFC)isshortedwithasolderbuild-up toprevent

damagetothelaserdiode.To connect tothePCboard, besureto

openbyremoving thesolderbuild-up, and finishtheworkquickly.

3. Take carenottoapplyexcessivestress totheflexibleboard(FFC).

4. Donotturnthevariableresistor(laserpoweradjustment). Ithas

alreadybeenadjusted.

-Grounding forelectrostaticbreakdownprevention

1. Humanbodygrounding

Use theanti-staticwrist straptodischargethestaticelectricity

fromyourbody.

2. Worktablegrounding

Putaconductivematerial (sheet) orsteel sheet on thearea where

thetraverse deck (optical pickup)isplaced, and ground thesheet.

Caution :

Thestaticelectricityofyourclothes will notbegroundedthrough

thewrist strap. So, take carenottolet yourclothes touchthe

traverse deck (optical pickup).

Caution whenReplacing theTraverse Deck :

Thetraverse deck has ashortpointshortedwithsoldertoprotect

thelaerdiodeagainst electroststics breakdown. Besuretoremove

thesolderfromtheshortpointbeforemaking connections.

5. Precaution of LaserDiode

butbesurethefollowings:

1. Donotdisassembletheoptical pick up unit, since radiation from

exposedlaserdiodeisdangerous.

2. Donotadjust thevariableresistoron thepick up unit. Itwas

alreadyadjusted.

3. Donotlookat thefocuslensusing optical instruments.

4. Recommend nottolookat pick up lensforalong time.
