INSTALLATION
WINDSHIELD
1. Cleanthewindshieldandtherubbercupsofthe
mountingbracket.Attachtherubbercupstothe
bracket.
2. Pushthebracketfirmlyontothewindshield.

cigarettelighter.
YoucanremovethedetectorbypressingtheEject key.
Dashboard
1. Placetheunitonthedashboardsothatithasaclear,
levelviewoftheroad.
The unit cannot be readjusted aer nal installaon.

You can remove the unit as needed.
5. Plugthepowercordintothedetector.
6. Plugthecigarettelighteradapterintothevehicle’s
cigarettelighter.
TURN UP
Oncethedetectorisinstalledandthecaristurnedon,turn
thePower/Volumedialawayfromyouuntilitclicks.The
unitisnowturnedon.
Theunitcyclesthroughthedisplayinthisorder:X-K-Ka-
Laser,thensignalstrengthexceptforLaser(L).Voice
announceseachband.
Oncethecycleiscomplete,thedetectorturnstostandby
mode.
DETECTION
TheLRD750detectsemissionsfromradargunsandsounds
anaudioalertforthedriver.Thedetectordetermines
whichbandrangethesignalisfromanddisplaysthat
frequencytypeonthedisplay(X,K,Ka,orLaser).The
frequencystrength(1thorough5)alsodisplaysinan
increasingbarformat.
False signals can come from other devices such as the
automac doors at a supermarket or even another
car’s cruise control; these devices operate in the
same frequency ranges as radar guns.
BANDS
TheLRD750recognizes:
• XBand:Thisbandwasthefirstfrequencybandassigned
topoliceradar.Itoperatedonalowerfrequency
(10.525GHz)withahigherpoweroutput.
• KBand:Thisbandisthemostcommonfrequencyused
inradardetectors(24.150).Itsrelativelysmall
wavelengthgivesitaclockingdistanceofabout1/4mile
although,dependingontheenvironment,itcandetect
upto2miles.TurnontheKbandfilterthroughthe
menustofilteroutweakerKbandfrequenciesand
reducefalsereadings.
• KaBand:Overtheyears,theKabandincorporatedthe
Ka-Band,theKaWide-Band,andtheKaSuperWide-
Band.Mostphotoradars(alsoknownasstoplight
cameras)usethisband.
POP™ is a single-pulse Doppler radar feature on some
K and Ka band radar guns. This type of radar gun is
a very sensive receiver; limit POP detect mode to
highway and rural driving.
• Laser:Policeusethelaser’snarrowerlightpulsesfor
speeddetectionasitismoreaccurateandfaster.Laser
beamsaremoredetectableaftertheyhavebouncedoff
theirtargetandbegintodisperseonthereturntrip.
MODES
TheLRD750operatesintwomodes:
• Highway.Providesaudioandvisualalertsanytimeall
bandsandlaseraredetected.Recommendedfor
highwayorruraldriving.(X,K,Ka,Laser)
• City.Providesaudioandvisualalertsanytimeallbands
andlaseraredetected.Providesastrongersignalsoit
canpickupweakertransmissions.(K,Ka,Laser)
VOICE ANNOUNCE
TheLRD750hasavoicefeaturethattellsyoutheunit
statusasitchanges.Forexample,iftheunitpicksupK
bandtransmissions,itannounces“Kband.”Turnthis
featureonandoffthroughthemenus.
