DETECTION
TheDFR3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L).Thefrequencystrength
(1through5)alsodisplaysasapplicable.Ifthereisa
specificalertcode,thatisalsodisplayed.
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DFR3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(pressandhold
CITY)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DFR3operatesinthree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forthe
Xbandsoitcanpickupweakersignals.(X,K,Ka,Laser)
• CityI.SimilartoCitymode,butnoXbandisdetected.
