Whistler’s City Modes are designed to reduce the
annoyance of automatic door openers and other
devices which share frequencies with police radar.
•
Press City to cancel Highway Mode and engage
City Mode. In City Mode, weak radar signals give
an initial alarm of two beeps, then remain quiet
until the signal becomes very strong. When the
signal strength increases, two additional beeps are
provided.
•
Press City again to enter City 1 Mode. Operation of
audio is the same as Highway Mode but in City 1
Mode, X band is lowered.

Press City again to enter City 2 Mode. Operation of
audio is the same as Highway Mode but in City 2
Mode, X band is not reported.
Caution:
Some towns/small cities may still be using X
band radar. City Modes do not change the audio alert
for laser.
•
Press City a fourth time to cancel City 2 Mode and
return the unit to Highway Mode.
