off, then on.
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 cancel Highway mode and engage City.
• Press City again to enter City 1 Mode
- display shows ‘C1 Lo X’.
• Press City again to enter City 2 Mode
- display shows ‘C2 No X’
• Pressing City a fourth time cancels City 2 Mode
and returns the unit to Highway Mode.
In City Mode, weak speed/safety radar signal 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. City 1 and 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: Some towns/small cities may still be using X
band radar. City Modes do not change the audio
alert for laser or VG-2.
Highway Mode
Highway mode provides full audio warnings any time
radar (X, K, Ka, Safety Radar) or laser signals are
detected, and is recommended for open road driving.

Backlight Setting
The backlighting can be programmed to be illuminated
all the time, only when alarming, or choices in-between.
The options are selectable by pressing and holding the
Dim button on the unit. The options are:
OFF-OFF = Backlight is off during normal operation
and off when the unit alarms
OFF- DIM = Backlight is off during normal operation
and dim when the unit alarms.
OFF-BRT = Backlight is off during normal operation
and bright when the unit alarms.
DIM-OFF = Backlight is dim during normal operation
and off when the unit alarms.
DIM-BRT = Backlight is dim during normal operation
and bright when the unit alarms.
Backlight will turn on, if selected, while the unit alarms
and remain on for 3 seconds after the unit stops
alarming. When any button is pressed the backlight will
illuminate at the dim setting and remain on for 3
seconds afterwards. The backlight will also illuminate
while in option mode.
Engaging/Disengaging VG-2
See Option Select Mode to turn this feature on/off.
When a VG-2 signal is detected, the VG-2 is sounded
and the VG-2 display flashes. After 3 seconds the
audio is canceled and the display no longer flashes.
This cycle is repeated if the VG-2 signal is again
detected.
During the period a VG-2 signal is detected, a radar
signal cannot be detected. However, because the VG-2
alert has confirmed that a patrol car is nearby, you are
already aware of the potential for speed monitoring
and can adjust your speed accordingly. Laser detection
is not affected while a VG-2 signal is detected.
Teach/Tutorial Mode
Provides simulated alerts for each type of signal.
