HIGHWAY VS CITY MODE Uniden's R7 radar detector operates in two different frequency (X, K, and Ka band) sensitivity modes - Highway and City. 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 reduce sensitivity so that false signals (such as from automatic door openers) are filtered out. Under factory default conditions (X band = off on all modes, 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.
