FEATURE DETAILS
HIGHWAY VS CITY MODE
Uniden’s R1 radar detector operates in three different frequency (X, K, and Ka
band) sensitivity modes - Highway, City, and Advanced. Highway mode is the most
sensitive, with maximum detection ranges while on the highway or open road.
City is on the lower end of the detection scale for city driving. City mode reduces
sensitivity so that false signals (such as from automatic door openers) are filtered
out.
Under factory default conditions (X band = off on all bands, K and Ka bands = on),
the band sensitivities are:
• Highway: X band off; K and Ka band full sensitivity.
• City: X band off and K band sensitivity reduced; Ka band full sensitivity.
• Advanced: Adjust the sensitivity level for each band as follows:
Sensitivity Level %
Sensitivity Adjustment (Attenuation)
100
Full sensitivity (Default)

– 1dB
