City/City 1/City 2 Modes

Whistler's City Modes are 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.

No rmal
• Press City again to enter City 1 Mode.
• Press City again to enter City 2 Mode.
• Press City a fourth time to cancel City 2 Mode and
returns the unit to Highway Mode.
In City Mode, weak radar signals give an initial alarm of two
beeps, and then remain quiet until 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
is lowered. 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.
