Introduction
Thankyou for purchasingan Albrecht AE72H handheldScanner.
Thescannerisversatile, compact, andeasytouse. You can
programupto100frequenciesintothe scanner'smemory.The
scanner letsyou scan transmissionsand ispreprogrammed with
service banks foryourconvenience.You canquicklysearch
those frequenciesmostcommonlyused by Airband and FM CB,
without tediousand complicated programming.
Useyour scanner tomonitor:
• Airband
• FM CB

About thisManual
Thescreen displaysused inthismanualare representationsof
whatmightappearwhen youuse yourscanner. Sincewhatyou
see dependson the frequenciesforyourarea andthesettings
you select, you mightnoticesomedifferencesbetween whatis
inthismanual andwhatappearson your scanner.
Togetthe mostfromthismanual, reviewthe contentstobecome
familiarwiththebasicfunctions available.Ifyou arenewto
scanning,besureto read thenextchapterfora quick
backgroundon thetechnologybehindthe hobby. Thefirstthing
you’llneed todoisinstall batteriesin thescanner.Then you
needtoconnect theincluded antennatothescanner.See
“Using Internal Batteries”on Page9and“Connectingthe
Antenna”on Page11if you needanyhelpdoingthis.
UnderstandingScanning
Thissection providesyou withbackground on how scanning
works.You don’t reallyneed toknowall of thistouseyour
scanner,butsomebackground knowledgewill helpyougetthe
most fromyour AE72H.
What isScanning?
UnlikestandardAMorFMradiostations,mosttwo way
communicationsdonottransmitcontinuously. YourAE72H
scans programmed channelsuntil itfindsan activefrequency,
then stopson that frequencyandremainsonthatchannelas
longasthe transmissioncontinues.When thetransmission ends,
thescanningcycleresumesuntilthescanner receivesanother
transmission.
What isSearching?
TheAE72Hcan searchforactivefrequencies. Thisisdifferent
fromscanningbecauseyouare searching forfrequenciesthat
havenotbeen programmed intothescanner.When youselect
frequencybandstosearch,thescannersearches for anyactive
frequencywithinthelowerand upper limitsyou specify.When
thescannerfindsanactive frequency,itstopson thatfrequency
aslongasthe transmission lasts.Ifyou thinkthefrequencyis
interesting,you can programitintooneofthebanks. Ifnot, you
can continuetosearch.
Conventional Scanning
Conventionalscanning isarelativelysimpleconcept. Each
groupofusersinaconventionalsystemis assignedasingle
frequency(for simplex systems)or twofrequencies(for repeater
systems). Anytimeone ofthemtransmits,theirtransmission
alwaysgoesouton the samefrequency.Upuntilthelate1980’s
thiswastheprimarywaythat radiosystems operated.
Even today,therearemany2-way radiouserswho operate
usingaconventional system:

8
• Aircraft
• Amateur radio
• PMR users
• BroadcastAM/FM/TV stations
• Manyotherbusiness radiousers
When you wanttostoreaconventionalsystem, all you need to
knowisthefrequenciesthey operate on.Whenyouare
scanningaconventional system, thescannerstopsverybriefly
on eachchannelto see ifthereisactivity.Ifthereisn’t, the
scanner quickly movestothenextchannel.Ifthereis,then the
scanner pauseson thetransmission untilit isover.
SimplexOperation
Simplex systemsuseasinglefrequencyforboth transmitand
receive.Mostradiosusingthistypeof operation arelimited to
line-of-sightoperation.This typeofradioisfrequentlyused at
construction job sites,and withinexpensiveconsumerradios
suchas PMR radios.Therangeistypically1.5-12 km,
depending upon theterrainandmanyother factors.
RepeaterOperation
Repeatersystemsusetwofrequencies:onetransmits fromthe
radiotoacentral repeater; theother transmitsfromtherepeater
toother radiosin thesystem. Witharepeater-based system, the
repeater islocated ontop ofatallbuildingoronaradiotower
thatprovidesgreatvisibilitytothearea ofoperation. Whena
usertransmits(on an inputfrequency), the signal ispicked upby
therepeaterandretransmitted (on anoutputfrequency). The
user’sradiosalways listen foractivityon theoutputfrequency
and transmiton theinputfrequency.Sincetherepeater is
located veryhigh,thereisaverylargelineof sight. Typical
repeatersystemsprovidecoverageouttoabouta40 kmradius

Belt Clip (with2screws)
Adapter
Battery set ( 2pcs NiMH )
Note: Ifanyof theseitemsaremissingordamaged, contact
your placeof purchase.
SettingUpYourScanner
Theseguidelineswill helpyou installand useyour new scanner:
• If yourscannerreceivesinterferenceor electrical noise,
movethescanneroritsantennaaway from the
source.
• Toimprovethescanner’sreception, usean optional
externalantennadesigned for multiband coverage.
(You canpurchasethistypeof antennaatalocal
electronics store). Ifthe optional antennahasno cable,
use50 Ohm coaxial cablefor lead-in.Amating plug
might be necessaryfor theoptionalantennas.
• Usean optional monoearphoneormono headset with
properimpedancefor privatelistening.Readthe
precautionson theinside front coverof thisOwners
Manual.
• Donotusethescannerinhigh-moisture environments
suchasthekitchen orbathroom.
• Avoid placingthescannerin direct sunlightor near
heatingelementsor vents.
Using InternalBatteries
You canpoweryourscannerusingthe supplied rechargeable
NiMH batteries( 2xAA).
Using Rechargeable Batteries
BeforeyouuseNiMHorNiCdbatteriesthefirsttime,you must
chargethem. Itmay happen,thatthefirstbatterycharging may
notreach the full capacity,butthe finalcapacitywill beokafter at
least 2-3timescharging.
Thescannerhasabuilt-incircuit thatletsyourechargeNiMHor
NiCdbatterieswhiletheyareinthescanner.
Tochargethebatteries;
1. Makesurethepoweristurnedoff.
2. Slidethebatterycompartment cover.
3. Install twobatteriesin thecompartmentas indicated by the
polaritysymbols(+and -) marked inside.

4. Replacethecover.
5. Connect thesupplied AC adaptor tothescanner’sDC 6V
socketto charge thebatteriesatleastforsome hoursbefore first
timeuse.
Using Non-RechargeableBatteries
You can alsousetwoalkalinebatteriesto poweryourscanner.
Beforeyou use alkaline batteries,youmust remove thestickerin
thecompartmentandmovetheswitch belowthesticker to
REG. ALK. BATT. position.
Notes:
• Useonlyfreshbatteriesof therequired size and
recommended type.
• Alwaysremoveoldorweakbatteries. Batteries can
leakchemicalsthatdestroy electronic circuits.
• Donotmixoldandnewbatteries, different types of
batteries(standard,alkaline,or rechargeable), or
rechargeablebatteriesof different capacities.
The switchis factorypreset to
NiMHbatteryand covered bya
sticker. Remove the sticker ifYou
want to use alkaline batteries

Notes:
• NiMH batterieslastlongeranddelivermore powerif you
occasionallylet them fully discharge. Todothis, simplyuse
thescanner untilit beeps every15 secondsand
flashes.
• TopreventdamagetoNiMH batteries,never chargethem
inan areawherethetemperatureis above45°C or below
4°C.
• If you connectan external powersource tothe scanner with
thebatteryswitchset to REG. ALK. BATT., thescanner
doesNOT chargethebatteries. Makesurethat you usethe

Using ACPower
You can powerthescannerusing thesupplied 6V, 500mAAC
adapter. Tousethescanneron ACpower, plug theACadapter
intoDC 6Von thesideofthescannerthen plugthe otherend
intoastandardAC outlet. Ifrechargeablebatteriesareinstalled
withoutremoving thesticker, or,afterremoving, makesurethat
thebatteryswitchiscorrectlyset to NI-MH BATT.,
Onlyin thisposition theadaptercan powerthescannerand
rechargesthe installed batteriesat thesametime.
