TelevisionandAudioSuggestions

Althoughtheseinvertersareshieldedandfilteredtominimizesignalinterference,someinterf erencewithyour

televisionpicturemaybeunavoidable,especiallywithweaksignals.However,herearesomesuggestionsthatmay

improvereception.

1. First,makesurethattelevisionantennaproducesaclearsignalundernormaloperatingconditions(i.e.,at

home

pluggedintoastandard110VACwalloutlet).Also,ensurethattheantennacableisproperlyshielded

andofgoodquality.

2. Changethepositionsoftheinverter,antennacablesandtelevisionpowercord.

3. Isolatethetelevision,itspowercordandantennacablesfromthe12‐voltpowersource

byrunningan

extensioncordfromtheinvertertothetelevisionset.

4. Coilthetelevisionpowercordandtheinputcablesrunningfromthe12‐voltpowersourcetotheinverter.

5. Attacha"FerriteDataLineFilter"tothetelevisionpowercord.Morethanonefiltermayberequired.

These

filtersareavailableatmostelectronicsupplystores.

Note

• Inexpensivesoundsystemsmayemita"buzzing"soundwhenoperatedwiththeinverter.Thisisdueto

BlownAutomotiveFuses

Dependingonthemakeandmodelofyourautomobile,runningthepowerinverternearfullcapacityfromyour

cigarettelighterportmayresultinablownautomotivecigarettelighterfuse.Thisfusewillneedtobereplaced

withthesamesizefuse.Pleasenote,ablownautomotivefusewillnotcause

damagetoyourcarwiring.Toavoid

blowinganautomotivefuseinthissituation,donotoperatethepowerinverterover200wattsforextended

periodsoftimefromyourcigarettelighteror12voltpowerport.

BlownPowerInverterFuses

Yourpowerinverterisequippedwitha20‐ampspadetypefuse.Withreasonablecareitshouldnotbenecessary

toreplacethesefuses.Mostblownfusesaretheresultofreversepolarityorashortcircuitwithintheapplianceor

equipmentbeingoperated.Ifthefusehappenstoblow,disconnect

theapplianceorequipmentimmediately,find

thesourceoftheproblem,repairit,andtheninstallanewfuse.

SourceofPower

Mostautomobileandmarinebatterieswillprovideanamplepowersupplytotheinverterfor30to60minutes

evenwhentheengineisoff.Actualtimemayvarydependinguponthe ageandconditionofthebattery,andthe

powerdemandbeingplacedonitbytheequipmentbeingoperated

withtheinverter.

Ifyoudecidetousetheinverterwhi le theengineisoff,werecommendthatyoustarttheengineeveryhourand

letitrunforapproximately10minutestorechargethebattery.Wealsorecommendthatthedevicepluggedinto

theinverterbeturnedOFFbefore

startingthevehicleengine.

Althoughitisnotnecessarytodisconnecttheinverterwhenturningovertheengine,itmaymomentarilyceaseto

operateasthebatteryvoltagedecreases.

Whentheinverterisnotsupplyingpower,itdrawsverylowamperagefromthebatteryandmaybeleftconnected

tothe

batteryforuptothreehours.

However,werecommendtheinverteralwaysbedisconnectedwhennotinuse.
