Iftheprovidedplugdoesnotfiteasilyintoyouroutlet,consultanelectricianforreplacementofthe
obsoleteoutletbeforeattemptingtopoweruptheamplifier.
Preventthepowercordfrombeingwalkedon,bent,stretchedorpinched,particularlyattheplugoratthe
pointwhereitexitsfromtheamplifier.
Whenuncertainaboutspecifications,pleasefirstconsultthePyleAudiowebsiteandseetheFAQs.
Ensurethisunitisplacedonastableandflatsurfaceandcanaccommodatetheweightofthisunit.
Unplugthisunitduringlightningstormsorwhenitisunusedforanextendedperiodoftime.

ormalfunctionsinanymanner.Thiswouldincludedamagetothepowersupplycordorplug,whenever
liquidhasbeenspilledorobjectshavefallenintothedevice,alsowhenthedevicehasbeenexposedtorain
ormoisture,whentheunitceasestooperatenormally,aswhenoriginallypurchased.
Iftheunitislikelytoundergoexcessvibrationthroughuse,yourmustproperlyinstalltheunitsecurelyandtherack
mountablereinforcementbracketsmustbeproperlyfitted.
Damagecausedbyinsufficientsupportisnotcoveredbythewarranty.
Topreventdamagetotheunit'spanels,alwaysuseprotectiveplasticcupsorwashersbeforetighteningmountingbolts.

Ventilationgapsbetweenunitsarenotrequired,howevercaremustbetakentoensurethatanunobstructedfreeflowof
cleanairispossiblefromthebackoftheunittothefront.Itisalsoimportantthatneitherairintakes,frontorsideexhaust
grillesarecovered.Theinternalairflowoftheseunitsaredesignedtominimizethemalfunctionoftheelectronics,and
promotecoolingair,foroptimalandsafeunitoperation.

PLEASENOTE:Usersmustensurethatanytypeofsmokeandrelatedsubstancesarenotallowedtoentertheamplifier.
Smokeyairiscorrosiveandprolongedexposurewillcauseirreparabledamagetoyouramplifier.
Donotexposetheamplifiertorainormoistureduringoperationorstorage.Iftheunitdoescomeintocontactwith
moisture,removetheACpowercordimmediatelyandleaveitinasuitablydryareatodry.Takeprecautionbefore
