6. Handling Precautions ForTraverse Deck
Thelaserdiodeinthetraverse deck (optical pickup)may break downduetopotential difference
causedbystaticelectricityofclothes or humanbody. So, becareful ofelectrostaticbreakdown
during repairofthetraverse deck (optical pickup).
-Handling oftraverse deck (optical pickup)
1. Donotsubject thetraverse deck (optical pickup)tostatic
electricityas itisextremelysensitivetoelectrical shock.
2. To preventthebreakdownofthelaserdiode, anantistatic
shorting pinisinsertedintotheflexibleboard(FFCboard).
3. Take carenottoapplyexcessivestress totheflexibleboard(FFC
board). Whenremoving orconnecting theshortpin, finishthejob
9

inas shorttimeas possible.
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)isplace, 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 ashortpointshortedwithsoldertoprotectthelaserdiodeagainst
electrostatics breakdown. Besuretoremove thesolderfrom theshortpointbeforemaking
connections.
