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

3. Protection Circuitry

Theprotection circuitrymay have operatedifeitherofthefollowing conditionsarenoticed:

-Nosound isheardwhenthepoweristurnedon.

-Sound stopsduring aperformance.

Thefunction ofthiscircuitryistopreventcircuitrydamageif, for example, thepositive and

negative speakerconnection wires are“shorted”, or ifspeakersystemswithanimpedance less

thantheindicatedratedimpedance oftheamplifierareused. / Ifthisoccurs, followtheprocedure

outlines below:

1. Turnoff thepower.

2. Determinethecause oftheproblemand correct it.

3. Turnon thepoweronce againafteroneminute.

Note:

Whentheprotection circuitryfunctions, theunitwill notoperate

unless thepowerisfirst turnedoff and thenon again.

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

laserpower);ithas beenadjustedat thefactory. / (as shownin

Fig.1 )

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

connections.

6. Precaution of LaserDiode

CAUTION:

Thisproduct utilizes alaserdiodewiththeunitturned“ON”,

invisiblelaserradiation isemittedfromthepick up lens.

1. Donotdisassemblythepick up unit, since radiation fromexposed

laserdiodeisdangerous.

2. Donotadjust thevariableresistoron thepick up unit. Itwas

alreadyadjusted.

3. Donotlock at thefocuslensusing optical instruments.

4. Recommend nottolock at pick up lensforalong time.

9. Operation Checks and Component Replacement

Procedures

-Thissection describes procedures forchecking theoperation of

themajorprintedcircuitboardsand replacing themain

components.

-Forreassemblyafteroperation checks orreplacement, reverse the

respectiveprocedures. Special reassemblyprocedures are

describedonlywhenrequired.
