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.
• Press City to engage City.
• Press City a second time to engage City 1.
• Press City a second time to engage City 1.
• Press City a third time to engage City 2.
• Press City a fourth time to cancel City 2 Mode and
return the unit to Highway Mode.
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.
