

CAUTION



Danger,riskofexplosionifbatterypacksaretamperedwith,

misusedorabused.Replaceanduseonlythosebattery

packssuppliedbyAudiotelInternationalLtd.

Donotshortcircuitthebatterypacks

Donotincinerateorsubjectbatterypackstoexcessiveheat

TheoryOfOperation-HarmonicRadar

Theharmonicsignalsproducedaredetectedbythetwo

receiversinSuperBroomandtheirrespectivesignalstrengths

displayed.

BecauseSuperBroomhasreceiversforbothsecondand

thirdharmonics,andbecauseelectronicandmetalnon-

linearjunctionsgivedifferingreturns,SuperBroomisable

toprovidetheuserwithdiscriminationbetweenelectronic

devicesandnon-electronic,metallicartefacts.

AlthoughthemainapplicationofSuperBroomisthe

detectionofelectronicdevices,thisprincipleisemployed

insomeequipmenttodetectconcealedman-mademetallic

artefacts.

Thismethodofdetectionistermed‘HarmonicRadar’.

InconventionalRadararadiosignalisemittedwhich

isreectedoffatargettoproduceanechoatthesame

frequency.SuperBroom’smethodofoperationistodetect

echoesatharmonicsofthesignalemitted.

SomeusersrefertoaHarmonicRadarasa‘Non-linear

JunctionDetector’.

ENVIRONMENTALCONDITIONS

TheSuperBroomhasbeendesignedtooperatewithinthe

followingconditions:

Temperatureconditionsof+5°Cto+35°C(TheLCDmay

slowdownat+5°C.)

POWERREQUIREMENTS

SuperBroomonlyoperatespoweredbyitsinternalbattery

pack.TheexternalAC/DCAdaptorisusedtorecharge

thebatteryonlyandcannotbeusedtodirectlypower

SuperBroom.

BATTERY

TheinternalrechargeableLithiumIonbatterypackgives

3-20hourscontinuoususe(dependentonthepoweroutput

setting).Thebatterywillneedtoberechargedwhenthefront

panelLCDdisplayshowsapproximately6.5V.Thebattery

isautomaticallyrechargedwhenexternalpowerisapplied

totheSuperBroomviatheexternalAC/DCAdaptor.Internal

protectioncircuitryprotectsthebattery.Ifforanyreason

thebatterysuffersanytransientfaultsuchasshort-circuit,

overchargingordeepdischarge,thepackwillshutdown.It

willremaininthisstateuntilrechargedbyconnectionofthe

externalAC/DCAdaptor.

IftheSuperBroomisleftswitchedon,asthebatterypower

levelfalls,thefollowingsequenceofeventswilleventually

occur:



SuperBroomentersaresetstate,thisisindicatedby

all6LEDsontheleft-handsideofthefrontpanel

THEORYOFOPERATION-HARMONICRADAR

ThissectionisintendedtoexplainhowSuperBroom

detectselectronicdevicesandwhyithastworeceivers.

Understandingthistheoryisnotessentialtooperationof

SuperBroombutshouldhelpusersperformafastersweep

andbemoreappreciativeofoperation.

PRINCIPLEOFOPERATION

SuperBroomdetectselectronicComponentsthatare:



Diodes



Transistors



IntegratedCircuits

Thesecomponentsareusedtomakeelectronicdevices

(togetherwithothercomponentssuchasresistorsand

capacitors,forexample).SuperBroomcandetectelectronic

devicesregardlessofwhetherthedeviceispoweredor

operationalalthoughthismayaffecthowwellitcanbe

detectedfromagivendistance.

SuperBroomdoesnotreacttoresistors,capacitors,

transformers,batteriesandothercomponentsthatdonot

containdiode-ortransistor-likematerials.

SuperBroomdoesnotdetectmetalobjectsexceptwhen

metallicsemi-conductingjunctionsareformed-thisis

explainedbelow.

THENON-LINEARJUNCTION

Distortionofasignalresultsingenerationofharmonicsof

theincidentsignal.Higherfrequenciesareproducedwhich

areawholenumbermultiples(integermultiples)-termed

‘harmonics’-oftheincidentsignal.

SettingUp

Atanytimeduringoraftertheabovesequenceattaching

theunittoanexternalpowersupplyviatheexternalAC/DC

AdaptorwillstarttorechargetheSuperBroombatterypack.

WARNING



Dangerofexplosionifbatteryisincorrectlyreplaced.

Replaceonlywiththesameorequivalenttyperecommended

bythemanufacturer.Disposeofbatteriesaccordingtothe

manufacturer’sinstructions.

CHARGINGTHEBATTERY

SuperBroomisdesignedtoautomaticallyenteradormant

statewhenpowerisappliedviatheexternalAC/DCadaptor,

(positivecentre),SuperBroominputisprotectedagainst,

reverse-polarityandover-current.

TheAC/DCAdaptorsuppliedwillworkwithACvoltages

from100to240VAC.

TheChargersocketislocatedontheright-handpanelof

yourSuperBroom.ItisrecommendedthattheSuperBroomis

lefttochargefor6hourstoensureafullcharge.

WhenconnectedtotheAC/DCAdpatortheBatteryCharge

StatusLEDonthefrontdisplaypanelisilluminatedRed.

WhenthebatteryisfullychargedthefrontpanelLED

changestoGreen.



Note



WhenyourSuperBroomisrstunpackedtheinternalbattery

packmaynotbefullycharged.



Caution



OnlyusemanufacturersrecommendedexternalAC/DC

adaptor.

PRACTICALCONSIDERATIONS-METALJUNCTIONS

Althoughmetaljunctionsusuallyresultinstrongerthird

harmonicandweakersecondharmonicreturnsignals

aparticularmetallicjunctionmaygivean‘electronic

Component’likereturn.

Metallicjunctionsareoftenverysensitivetovibrationand

thisvibrationcanbeheardifLISTENisselected(alsoselect

‘2nd’)andtheareatappedwitharubberfacedhammeror

otherobjectthatwillnotcausematerialdamage.

Aboxofpaperclipsisagoodexampleofametallictarget

andexperimentationwilldemonstratethevalueofLISTEN.

ReplacingBatteries



Note



EnsureAC/DCadaptorisisolatedfromtheACmainsand

removedbeforereplacingbatterypack

Thebatterycompartmentisaccessedviaaremovabledoor

onthebaseoftheSuperBroomunit(seeopposite).The

doorissecuredbya1/4turnscrew.TheBatterypacksare

speciallyconguredforusewiththeSuperBroomandshould

onlybereplacedwithAudiotelsuppliedbatterypacks.

Thebatterypackshavebuilt-inprotectioncircuitryandare

designedtopreventreversepolarityconnection.

DisposalofBatteries

Attheendofabatterypack’susefullifeitshouldbereturned

toAudiotelforcorrectdisposal.Incorrectdisposalmaycause

seriousinjury.

Operation

PRACTICALCONSIDERATIONS-INNOCENTELECTRONICITEMS

Mostelectronicitemswillbevisibleandthereforeobvious

sourcesofafalsealarms.Thetransmitterpoweroutputand

receiversensitivityofSuperBroomarebothhighenoughto

detectlarge(inthiscontext‘large’referstotheir‘detection

size’ratherthanphysicalsize)objectsfrommanymetres

away.Ifitisnotpracticaltomoveelectronicitemsthenthe

powersettingmustbereducedtolimitthedetectionrange.

Thiscan,ofcourse,makedetectionof‘small’targetsmore

difcult.

Someelectronicitemsmaynotbeobvious.Examples

include:

Electronicitemsontheothersideofawall,door,ceilingor
