OPERATION

City/City 1/City 2 Mode
Whistler’s Three Stage City Mode is designed to reduce the
annoyance of automatic door openers, intrusion alarms and
other devices which share frequencies with police radar.
Generally X band is used for these devices.

• Pressing City a second time engages City 1. Display shows:

• Pressing City a third time engages City 2. Display shows:

• Pressing City a fourth time cancels City 2 Mode and

returns the unit to Highway Mode. Display shows:

In City Mode, weak speed/safety radar signals give an initial
alarm 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.
CAUTION:

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 unit receives
a strong radar signal, the unit performs the Auto Quiet
feature.City Modes do not change the audio alert for laser
or VG-2.
