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
Caution :

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.
