remains quiet unless the signal becomes very
strong. When the signal strength increases, two
additional beeps are provided. City 1 and City 2
Modes operate the same as Highway Mode, but
in City 1 Mode, only the X band sensitivity is low-
ered. In City 2 Mode, X-band is not detected.
Caution: Some towns/small cities may still be

using X band radar. City Modes do not change

the audio alert for laser or VG-2.

OPERATION

Highway Mode

time radar (X, K, Ka, Safety Radar) or laser sig-
nals are detected, and is recommended for open
