8 AC Mains Input, Switch and Fuse Assembly
Aconventional,15-ampereIECstandardpowercordisusedwiththeSC-1.
AhighqualityACmainscordisincludedwiththeproduct,althoughthe
useofthestandardizedIECreceptaclemeansthatyoumayeasilysubsti-
tuteanotherhighqualityACmainscordifyouwish.
 Warning! YournewWisdomAudioSC-1hasbeensafety-testedandis
designedforoperationwithathree-conductorpowercord.Donot
defeatthe“thirdpin”orearthgroundoftheACpowercord.
An AC mains switch islocatedjustabovetothepowercordontherear
paneloftheSC-1.Thisswitchmaybeusedtodisconnecttheunitfromthe
ACmainswithouthavingtoactuallyunplugtheSC-1fromthewalloutlet.
Ifyouplantobeawayforanextendedperiod,orhaveanyotherreasonto
turntheSC-1completelyoff,youmayeitherunplugtheSC-1oryoumay
usetheAC mains switch.
 Danger! Potentiallydangerousvoltagesandcurrentcapabilitiesexistwithin
yourSC-1.DonotattempttoopenanyportionoftheSC-1’scabinet.
Therearenouser-serviceablepartsinsideyourSC-1.Allserviceof
thisproductmustbereferredtoaqualiedWisdomAudiodealeror
distributor.
WerecommendthatcarebetakentoensurethatallACplugsfortheequipment
inthesystembewiredsoastoensureproperACpolarity.Doingsowillmini-
mizenoiseinthesystem.
IntheU.S.,asimpleACmainstester(foundatanyhardwarestore)cantestto
ensurethatyourelectricaloutletsarewiredproperly.Elsewhereintheworld
(forexample,inEuropeanUnioncountries),theACmainsplugsthemselvesare
notalwayspolarized.Yourdealercantestfortheproperorientationoftheplug
intheoutlet.Insuchacase,itisgoodpracticetomarkbothplugandoutletto
ensurethatallproductsremainintheproperorientationshoulditbecomenec-
essarytotemporarilydisconnectthesystem(asforexample,duringanelectrical
storm).
Finally,theWisdomAudioSC-1incorporatesafuseblockthatprotectsboththe
liveandneutral(ground)sidesofthecircuit.IfyourSC-1ispluggedintoanAC
outletthatyouknowislive(plugalampintoitasatest),andyetappearstobe
off,checkthefollowing:
1 ChecktheACcordtomakesureitisnotdamaged.
2. ChecktheACmainsswitchtoensurethatitisOn(theside
withthestraightlineisdepressed,notthe“O”side).
3. Ifthatdoesnotresolvetheproblem,turnOfftheACmains
switch(“O”)andthendisconnectthepowercordfromtheAC
mainsreceptacle.
4. Usingasmallscrewdriver,gentlypryopenthefuseblockcover
atthetopedgeoftheassembly.(Youmaybeabletodoitwith
justyourngernail.)
