OPERATION

Quiet Mode

Quiet cancels audio during an alert and any new
alert within 20 seconds. After 20 seconds,
approximately 2 beeps are provided on any new
alert and unit then remains quiet.

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 button to cancel Highway Mode
and engage City Mode.
• Press City button again to enter City 1 Mode
• Press City button again to enter City 2 Mode
• Press City button 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. City 1 and City 2
Modes operate the same as Highway Mode, but
in City 1 Mode, X band requires a stronger
signal to alert. 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.

OPERATION

Compass Calibration

(XTR-540
The unit needs to be calibrated in order for the
compass to provide accurate headings. To calibrate
the unit, perform the following procedure:
1 1 . . Mount the unit level in the center of the
vehicle's windshield. Make sure there are no
magnetic sources near the detector (i.e., speaker).
2 2 . Select a large, clear area (parking lot or field)
.
without any power lines
3 3 . Press the Menu button until display shows
C C A A L L M M O O D D E E . Then press the Power/BL and Quiet/Vol
buttons simultaneously. The display shows (scrolling):
4 4 . If calibration does not automatically finish, press the
Power/BL and Quiet/VOL buttons simultaneously to
complete calibration. The unit will beep twice and
display:
Important: If the unit mounting is relocated in the
vehicle, (i.e., visor to windshield mounting or dash
mounting), or if the unit is moved to another vehicle,
you must recalibrate the compass.
VG-2 Mode
See Option Select Mode to turn this feature
on/off. When a VG-2 signal is detected, the VG-2
alert is sounded and the display flashes "VG-2".
After 3 seconds, the audio is canceled and the
display no longer flashes. This cycle is repeated
if the VG-2 signal is detected again.
D D u u r r i i n n g g t t h h e e p p e e r r i i o o d d a a V V G G - - 2 2 s s i i g g n n a a l l i i s s d d e e t t e e c c t t e e d d , , a a

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. (See
