In City Mode, weak speed/safety radar signals give an initial
a l a rm of two beeps, and then remains quiet unless the signal
becomes very strong. When the signal strength increases, two
additional beeps are provided. In City 1 Mode, only the X band
sensitivity is lowered. City 1 & City 2 Modes operate the same as
Highway Mode, but in City 1 Mode, only the X- band sensitivity
is lowered. In City 2 Mode, X-band is not detected.
C A U T I O N :
When selecting this mode, 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 unitre c e i v e s
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.
