MODES (HIGHWAY, CITY, AUTO, AND ADVANCED)
Uniden’s R8 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, K, and Ka bands full sensitivity.
• City: X and K bands sensitivity reduced; Ka band full sensitivity.
• Auto: Auto mode will switch the R8 between Highway and City depending on the
Auto City Speed menu setting (see page 14). If the driving speed is over the
Auto City Speed setting, R8 operates in Highway mode. If it is below the set speed,
R8 operates in City mode. Sensitivity is the same as Highway and City settings.
If GPS is not connected, R8 automatically operates in Highway mode.
• Advanced: Adjust the sensitivity level for each band.
