FEATURE DETAILS
HIGHWAY VS CITY MODE
Radar detectors operate with various sensitivity levels. These levels determine the types of signals and signal
ranges (bands) detected. Highway mode is the most sensitive level while City mode is the least sensitive. If the X
band is left on in City mode, a radar detector can pick up many X band signals (such as garage door openers) that
generate false alerts. The LRD850 turns off the X band for City mode. When you are on the highway, there is less
chance of picking up X band false alerts, so the LRD keeps the X band on.
