1. SafetyPrecaution
1.1. General Guidelines
1. IMPORTANTSAFETYNOTICE/ Therearespecial components
usedinthisequipmentwhichareimportantforsafety. These parts
aremarkedbyintheSchematicDiagrams, CircuitBoardLayout,
ExplodedViewsand ReplacementParts List. Itisessential that
these critical parts shouldbereplacedwithmanufacturer’s
specifiedparts topreventX-RADIATION, shock fire, orother
hazards. Donotmodifytheoriginal design withoutpermission of
manufacturer.
2. AnIsolation Transformershouldalwaysbeusedduring the
servicing ofACAdaptorwhose chassisisnotisolatedfromtheAC
powerline. Use atransformerofadequate powerrating as this
protects thetechnicianfromaccidents resulting inpersonal injury
fromelectrical shocks. Itwill alsoprotect ACAdaptorfrombeing
damagedbyaccidental shorting that mayoccurduring servicing.
3. Whenservicing, observetheoriginal leaddress. Itashortcircuit
isfound, replace all parts whichhavebeenoverheatedor
2

damagedbytheshortcircuit.
4. Afterservicing, see toitthat all theprotectivedevices suchas
insulation barriers, insulation papersshieldsareproperlyinstalled.
5. Afterservicing, make thefollowing leakagecurrentchecks to
preventthecustomerfrombeing exposedtoshock hazards.
2. Warning
2.1. Prevention ofElectroStaticDischarge(ESD)toElectrostatically
/ Sensitive(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 onlyanantistaticsolderremoval device. Somesolderremoval
devices notclassifiedas “antistatic(ESDprotected)”cangenerate
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 powerisappliedtothechassisor circuit, and observe all othersafetyprecautions.
8. Minimizebodilymotionswhenhandling unpackagedreplacement
ES devices. (Otherwise harmless motion suchas thebrushing
togetherofyourclothes fabricorthelifting ofyourfootfroma
carpetedfloorcangenerate staticelectricity(ESD)sufficientto
damageanES device).
2.2. Service caution basedon legal restrictions
2.2.1. General description aboutLeadFree Solder(PbF)
Theleadfree solderhas beenusedinthemounting process ofall electrical componentson the
printedcircuitboardsusedfor thisequipmentinconsidering thegloballyenvironmental
conservation.
Thenormal solderisthealloyoftin(Sn)and lead(Pb). Ontheotherhand, theleadfree solderis
thealloymainlyconsistsoftin(Sn), silver(Ag)and Copper(Cu), and themelting pointofthelead
free solderishigherapprox.30 degrees C(86°F)morethanthatofthenormal solder.

(See rightfigure)
Service caution for repairworkusing LeadFree Solder(PbF)
-Theleadfree solderhas tobeusedwhenrepairing theequipment
forwhichtheleadfree solderisused.
(Definition:Theletterof“PbF”isprintedon thePCB using thelead
free solder.)
-To putleadfree solder, itshouldbewell moltenand mixedwiththe

original leadfree solder.
-Removetheremaining leadfree solderon thePCB cleanlyfor
soldering ofthenew IC.
-Since themelting pointoftheleadfree solderishigherthanthat of
thenormal leadsolder, ittakes thelongertimetomelttheleadfree
solder.
-Use thesoldering iron (morethan70W)equippedwiththe
temperaturecontrol aftersetting thetemperatureat 350±30
degrees C(662±86°F).
RecommendedLeadFree Solder(Service PartsRoute.)
-Thefollowing 3types ofleadfree solderareavailablethrough the
service parts route.
