1. SafetyPrecaution
(This“SafetyPrecaution”isappliedonlyinU.S.A.)
1. Beforeservicing, unplug thepowercordtopreventanelectric
shock.
2. Whenreplacing parts, use onlymanufacturer’srecommended
components forsafety.
3. Check thecondition ofthepowercord. Replace ifwearordamage
isevident.
4. Afterservicing, besuretorestoretheleaddress, insulation
barriers, insulation papers, shields, etc.
5. Beforereturning theservicedequipmenttothecustomer, besure
tomake thefollowing insulation resistance test to
preventthecustomerfrombeing exposedtoashock hazard.
1.1. Insulation Resistance Test
1. Unplug thepowercordand shortthetwoprongsoftheplug witha

jumperwire.
2. Turnon thepowerswitch.
3. Measuretheresistance valuewithohmmeterbetweenthejumper

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.

6. Precaution of LaserDiode
CAUTION:
Thisunitutilizes aclass 1laser.
Invisiblelaserradiation isemittedfrom theoptical pickup lens.
Whentheunitisturnedon:
1. Donotlookdirectlyintothepick up lens.
2. Donotuse optical instruments tolookat thepick up lens.
3. Donotadjust thepreset variableresistoron thepickup lens.
4. Donotdisassembletheoptical pick up unit.
5. Iftheoptical pick up isreplaced, use themanufacturer’sspecified
replacementpick up only.
6. Use ofcontrol oradjustments orperformance ofprocedures other
