5. 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

-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.
