In City Mode, weak speed/safety radar signals give an initial
a l a rm of two beeps, and then the unit remains quiet unless
the signal becomes very strong. When the signal stre n g t h
i n c r eases, two additional beeps are provided. In City 1
Mode, only the X band sensitivity is lowered. In City 2 Mode,
X-band is not detected. CAUTION: Some towns/small cities
may still be using X band radar.
If Auto Quiet is engaged in City 1 or City 2 modes and the
unit receives a strong radar signal, the unit perf o rms the Auto
Quiet feature. City Modes do not change the audio alert for
laser or VG-2.
