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 topreventthe
customerfrombeing exposedtoashock hazard.
1.1. Insulation Resistance Test
1. Unplug thepowercordand shortthetwoprongsoftheplug witha
jumperwire.
2. Turnon thepowerswitch.
3. Measuretheresistance valuewithohmmeterbetweenthejumper

outlines below:
1. Turnoff thepower.
2. Determinethecause oftheproblemand correct it.
3. Turnon thepoweronce againafteroneminute.

5. Handling Precautions forTraverse Deck
Thelaserdiodes inthetraverse deck (optical pickup)may break downduetopotential difference
causedbystaticelectricityofclothes or humanbody. / So, becareful ofelectrostaticbreakdown
during repairofthetraverse deck (optical pickup).
5.1. Handling thetraverse deck / (optical pickup)
1. Thetraverse deck (optical pickup)isanextremelyhigh-precision
construction and must notbesubjectedtoimpact, excessive
vibration, orothertypes ofrough handling.
2. Inordertopreventstaticelectricitydamagetothelaserdiode, use
ashortpinorsimilartool toshorttheoptical pickup’sflexible
circuitboardsaftertheyhavebeendisconnectedfromthemain
circuitboard.
3. Handletheflexiblecircuitboardswithcare;excessiveforce could
cause themtobebroken.
4. Donotturnthepre-set variableresistor(foradjustmentofthe

5.2. Grounding forelectrostaticbreakdownprevention
1. Humanbodygrounding / Use theanti-ataticwrist strapto
dischargethestaticelectricityfromyourbody.
2. Worktablegrounding / Putaconductivematerial (sheet) orsteel
sheet on thearea wheretheoptical pickup isplaced, and ground
thesheet. (sa shownin Fig.2 )
Fig.2
Caution:
Thestaticelectricityofyourclothes will notbegroundedthrough
thewrist strap. / So, take carenottolet yourclothes touchthe
traverse deck (optical pickup)
5.3. Caution whenReplacing theTraverse Deck
Thetraverse deck has ashortpointshortedwithsolderprotectthelaserdiodeagainst
electrostaticbreakbown. Besuretoremove thesolderfrom theshortpointbeforemaking
