1. SafetyPrecautions
1.1. GENERALGUIDELINES
1. Whenservicing, observetheoriginal leaddress. Ifashortcircuit
isfound, replace all parts whichhavebeenoverheatedor
damagedbytheshortcircuit.
2. Afterservicing, see toitthat all theprotectivedevices suchas
insulation barriers, insulation papersshieldsareproperlyinstalled.

3. Afterservicing, carryoutthefollowing leakagecurrentchecks to
preventthecustomerfrombeing exposedtoshock hazards.
1.1.1. LEAKAGE CURRENTCOLDCHECK
1. Unplug theACcordand connect ajumperbetweenthetwoprongs
on theplug.
2. Measuretheresistance value, withanohmmeter, betweenthe
jumperedACplug and eachexposedmetalliccabinet parton the
equipmentsuchas screwheads, connectors, control shafts, etc.
Whentheexposedmetallicparthas areturnpathtothechassis,
thereading shouldbebetween1M and 5.2M . / Whenthe
exposedmetal does nothaveareturnpathtothechassis, the
reading must be . Figure1
1.1.2. LEAKAGE CURRENTHOTCHECK (See Figure 1.)
1. Plug theACcorddirectlyintotheACoutlet. Donotuse an
isolation transformerforthischeck.
2. Connect a1.5k , 10 watts resistor, inparallel witha0.15 F
capacitors, betweeneachexposedmetallicparton theset and a
good earthground suchas awaterpipe, as shownin Figure 1.
3. Use anACvoltmeter, with1000 ohms/voltormoresensitivity, to
measurethepotential across theresistor.
4. Check eachexposedmetallicpart, and measurethevoltageat
6

eachpoint.
5. Reverse theACplug intheACoutlet and repeat eachoftheabove
measurements.
6. Thepotential at anypointshouldnotexceed0.75 volts RMS. A
leakagecurrenttester(Simpson Model 229 orequivalent) maybe
usedtomake thehotchecks, leakagecurrentmust notexceed1/2
milliamp. Incase ameasurementisoutsideofthelimits specified,
thereisapossibilityofashock hazard, and theequipmentshould
berepairedand recheckedbeforeitisreturnedtothecustomer.
1.2. BeforeRepairand Adjustment
DisconnectACpower, dischargePowerSupplyCapacitorsC5700, C5717, C5718, C5742, C5796
through a10 , 10 Wresistor toground.
DONOTSHORT-CIRCUITDIRECTLY(withascrewdriverblade, for instance), as thismay destroy
solidstatedevices.
Afterrepairsarecompleted, restorepowergraduallyusing avariac, toavoidovercurrent.
Currentconsumption atAC120 V, 60 HzinNOSIGNALmodevolumeminimal shouldbe~900 mA.
1.2.1. Caution for fuse replacement
1.3. 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 of
theamplifierareused.
Ifthisoccurs, followtheprocedureoutlines below:
1. Turnoff thepower.
2. Determinethecause oftheproblemand correct it.
3. Turnon thepoweronce againafteroneminute.

Whentheprotection circuitryfunctions, theunitwill notoperateunless thepowerisfirstturned
off and thenon again.
2. Prevention of ElectroStaticDischarge (ESD) to
ElectrostaticallySensitive(ES) Devices
Somesemiconductor (solidstate)devices canbedamagedeasilybystaticelectricity. Such
componentscommonlyarecalledElectrostaticallySensitive (ES)Devices. Examples oftypical
ES devices areintegratedcircuitsand somefield-effecttransistorsand semiconductor "chip"
components. Thefollowing techniques shouldbeusedtohelpreduce theincidence of
componentdamagecausedbyelectro staticdischarge(ESD).
1. Immediatelybeforehandling anysemiconductorcomponentor
semiconductor-equippedassembly, drainoff anyESDon your
bodybytouching aknownearthground. Alternatively, obtainand
wearacommerciallyavailabledischarging ESDwrist strap, which
shouldberemovedforpotential shock reasonspriortoapplying
powertotheunitundertest.
2. Afterremoving anelectrical assemblyequippedwithES devices,
place theassemblyon aconductivesurface suchas aluminum
foil, topreventelectrostaticchargebuildup orexposureofthe
assembly.
3. Use onlyagrounded-tipsoldering iron tosolderorunsolderES
devices.
4. Use onlyananti-staticsolderremoval device. Somesolder
removal devices notclassifiedas "anti-static(ESDprotected)"can
generate electrical chargesufficienttodamageES devices.
5. Donotuse freon-propelledchemicals. These cangenerate
electrical charges sufficienttodamageES devices.
6. DonotremoveareplacementES device fromits protective
packageuntil immediatelybeforeyou arereadytoinstall it. (Most
replacementES devices arepackagedwithleadselectrically
shortedtogetherbyconductivefoam, aluminumfoil orcomparable
conductivematerial).
7. Immediatelybeforeremoving theprotectivematerial fromthe
leadsofareplacementES device, touchtheprotectivematerial to
thechassisorcircuitassemblyintowhichthedevice will be
installed.
Caution

Besureno powerisappliedtothechassisorcircuit, and observe
all othersafetyprecautions.
8. Minimizebodilymotionswhenhandling unpackagedreplacement
ES devices. (Otherwise harmless motion suchas thebrushing
togetherofyourclothes fabricorthelifting ofyourfootfroma
carpetedfloorcangenerate staticelectricity(ESD)sufficientto
damageanES device).
3. Precaution of LaserDiode

Thisunitutilizes aclass 1laser.
Invisiblelaserradiation isemittedfromtheoptical pickup lens.
Wavelength:662nm(DVD)/785nm(CD).
Maximumoutputradiation powerfrompickup:100 W/VDE
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
thanthose specifiedhereinmayresultinhazardousradiation

4. About Lead Free Solder(PbF)
Distinction ofPbF PCB: PCBs(manufactured)using leadfree solderwill have aPbF stampon the
PCB.
Caution:
-Pbfree solderhas ahighermelting pointthanstandardsolder;
Typicallythemelting pointis50 -70°F(30 -40°C)higher. Please
use ahigh temperaturesoldering iron. Incase ofthesoldering iron
withtemperaturecontrol, please set itto700 ±20°F(370 ±10°C).
-Pbfree solderwill tend tosplashwhenheatedtoo high (about
1100°F/ 600°C).
Whensoldering orunsoldering, please completelyremoveall ofthe
solderon thepinsorsolderarea, and besuretoheat thesoldering
points withthePbfree solderuntil itmelts enough.
5. Handling Precautions forTraverse Unit
Thelaserdiodeintheoptical pickup unitmay break downduetostaticelectricityofclothes or
humanbody. Special caremustbetakenavoidcaution toelectrostaticbreakdownwhen
servicing and handling thelaserdiode.
5.1. CautionstoBeTakeninHandling theOptical Pickup Unit
Thelaserdiodeintheoptical pickup unitmay bedamagedduetoelectrostaticdischarge
generating from clothes or humanbody. Special caremustbetakenavoidcaution to
electrostaticdischargedamagewhenservicing thelaserdiode.
1. Donotgiveaconsiderableshock totheoptical pickup unitas it
has anextremelyhigh-precise structure.
2. To preventthelaserdiodefromtheelectrostaticdischarge
damage, theflexiblecableoftheoptical pickup unitremoved
shouldbeshort-circuitedwithashortpinoraclip.
3. Theflexiblecablemaybecutoff ifanexcessiveforce isappliedto
it. Use caution whenhandling theflexiblecable.
4. TheantistaticFPCisconnectedtothenew optical pickup unit.
Afterreplacing theoptical pickup unitand connecting theflexible
cable, cutoff theantistaticFPC.
