Mounting Guidelines
• Mount the unit as low as possible near the
center of the windshield.
• Do not mount the unit behind wipers,
ornaments, mirrored sunscreens, etc. These
obstructions have metal surfaces which can
affect radar and laser signals and reduce
critical warning time. (Regular tinted glass
does not affect reception.)
• Some windshields have an Instaclear™ or
Electriclear™ type coating, which affect radar
signals. Consult your dealer or the vehicle’s
owner’s manual to determine if your windshield
has this coating.
• Avoid placing the unit in direct contact with

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
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

bright when the unit alarms.
DIM-OFF = Backlight is dim during normal operation and
off when the unit alarms.
DIM-DIM = Backlight is dim during normal operation and
dim when the unit alarms.
DIM-BRT = Backlight is dim during normal operation and
bright when the unit alarms.
BRT-BRT = Backlight is bright 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.
Low Profile Alert Periscopes
Whistler’s Low Profile Alert Periscopes provide an
added attention getting visual alert. The two extra
LED’s flash on and off when the unit alarms to
provide a unique visual alert. This alert can be
programmed through the Option Select Mode to
be: ON, OFF, or FLASHING during alerts.
Compass Calibration (XTR-540 only)
The unit needs to be calibrated in order for the
compass to provide accurate headings. To calibrate
the unit, perform the following procedure:
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. Select a large, clear area (parking lot or field)
without any power lines.
3. Press the Menu button until display shows
CAL MODE. Then press the Power/BL and Quiet/Vol
buttons simultaneously. The display shows (scrolling):
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
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.
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. (See
page 18 for more information)

button to turn the unit back on. You can manually
engage the Auto Shut Off Mode by pressing and
holding the City button until one beep is heard.
Refer to “Option Select Mode” for instructions
for changing the Auto Shut Off Mode settings.
Filter Mode
There are times when a radar detector can emit
the same frequency as police radar and can
cause your detector to falsely alarm. Sometimes
a detector can display a signal when picking up
another radar detector in vehicle close by. The
Whistler Filter Mode option provide a method
to study the signal which will verify if the signal
is a legitimate police radar or a false alert from
another detector.
Filter: Allows for normal filtering.
Filter 1: Provides an extra step to analyze the signals
that may come from other detectors.
Filter is the factory default and should provide adequate
filtering for most conditions. If you experience excessive
alerts due to radar detectors in other vehicles, try the
Filter 1 option. Filter Mode functions in both Highway
and City Modes. See Option Select Mode to change
Filter settings.
Safety Warning System™
In communities where transmitters are located,
the Safety Warning System™ displays over 60
text messages. When Safety Radar is detected,
a unique audio alert sounds.
Safety Warning System Text
Example: Poor - Road - Surface.
Note: Not all areas have Safety Warning System™
POP™ Mode Alerts
Because POP Mode radar utilizes the same
K or Ka band frequencies, POP™ Mode Alerts will be
displayed as regular radar alerts.
Speed Radar Audio/Visual Alerts
When X, K, or Ka is detected, the band ID and
signal strength are displayed. The audio alert is
continuous and has a pattern like a geiger
counter. The faster the beep, the closer or
stronger the radar source.
Laser Audio/Visual Alerts
When a laser signal is detected, the audio alert is
continuous for a minimum of 3 seconds.
• The Display Shows:
Pulse Protection®
Pulse (instant-on) radar is more difficult to
detect than conventional radar because it
remains ‘off’ until activated to measure the speed
of a targeted vehicle.
When a pulse type transmission is detected, the
Whistler detector sounds an urgent 3-second
audio warning and the display shows:
After the 3-second pulse alert, the standard alert
pattern continues for as long as the signal is
It is important to respond promptly to a pulse
alert, since warning time may be minimal.
VG-2 Audio/Visual Alerts
Note: You must turn this feature on before it will
detect VG-2.
When a VG-2 signal is detected, the detector ‘hides’ its
own radiated signal and becomes undetectable by
the VG-2.
Every 30 seconds, the detector checks for a VG-2
signal. If a VG-2 signal is still present, the unit
continues to hide and repeats the VG-2 alert. If no
signal is detected, two beeps are provided,
indicating an ‘all clear’ condition. During a VG-2
Alert X, K, and Ka band signals cannot be
received (Reference page 21 for VG-2 information).
Alert Priority
When two or more signals are received at the
same time, the alert priority is:
1. Laser
2. VG-2
3. Speed Radar
4. Safety Radar
If X band is alerting, then suddenly a VG-2
signal is detected, the VG-2 warning will
override the X band alert.

Care And Maintenance
During the summer months, avoid prolonged
exposure to direct sunlight by removing your unit
from the dash when your vehicle is parked for an
extended period of time. Do not spray water,
cleaners, or polishes directly onto the unit. The
spray may penetrate through the openings and
damage the unit. Also, do not use any abrasive
cleaners on the unit’s exterior.
As with all battery operated devices remove the
batteries when the unit will not be used for an
extended period of time. Damage caused by
leaky or improperly charged batteries are not
covered under warranty.
This device complies with part 15 of the FCC
Rules. Operation is subject to the following two
(1) This device may not cause harmful interference, and
(2) this device must accept any interference
received, including interference that may cause
undesired operation.
Important: FCC (Federal Communications
Commission) requirements state that changes or
modifications not expressly approved by
Whistler could void the user’s authority to
operate the equipment.
A radar gun operates by transmitting radio
waves at certain frequencies which reflect off
objects and are picked up by the radar gun’s
receiving section. When a radar beam reflects
off a moving target, a measurable frequency shift
occurs. The radar unit converts this shift into miles
per hour to determine your vehicle’s speed.
Currently, the FCC permits operation of traffic
radar guns at X Band (10.500 - 10.550 GHz), K
Band (24.050 - 24.250 GHz), and Ka Band (33.400
- 36.000 GHz).
Note: A radar detector will not alarm if an
officer is not transmitting on any one of the
above radar bands.
In Most States YES!
Laser-Radar detectors are legal in every state for
automobiles and light trucks (under 10,000 lbs.)
except Virginia and Washington, D.C., which
have local regulations restricting the use of
radar receivers in any vehicle.
Radar Facts
POP™ Mode
POP™ Mode is a feature on some radar guns
operating on K and Ka bands. When the gun is
in POP™ Mode and activated, a brief burst of
energy, less that 1/15 of a second, is transmitted
and the vehicle’s speed is quickly acquired. A
detector without POP™ Mode detection
capability cannot respond to this brief
Laser Facts
It’s well documented that many radar guns
cannot reliably provide the speed of a targeted
vehicle that is traveling in a group of vehicles. In
contrast, a laser gun can target a specific vehicle
out of a line of traffic and determine its speed.
The advantage of laser over radar in terms of
target identification is the result of the laser gun’s
narrow beam. A radar gun’s transmission can
cover more than a four-lane highway at a distance
of 1,000 feet, compared with a laser gun’s
transmission which covers about 3 feet at the
same distance. For best protection, keep these
points in mind:
• Because the vehicle’s license plate or
headlights are the laser gun’s primary targets,
mounting the Whistler detector on the
dashboard can improve laser detection at
short range.
• Do not follow closely behind any vehicle. If you
can’t see past a vehicle ahead of you, chances
are your detector won’t either.
• The receiving range of laser signals will
not be the same as radar signals. Laser
guns are most often used at short range.
Whistler Laser-Radar detectors receive all current
laser guns which operate at a laser wavelength of 905
+/- 10mm.
•Pro Laser™ I II III
•LT1 20-20
•Ultra Lyte
Laser Tips
If you are the targeted vehicle, a laser gun can
often determine your speed within a few
seconds after you receive an alert. In this
situation, there is generally no time to safely
adjust your speed. However, if you are traveling
near or behind the targeted vehicle, and receive
an alert, response time should be sufficient. Any
laser alert, regardless of duration, requires
immediate action!
Other Speed Detection Systems
Several techniques other than radar or laser are
used to measure vehicle speeds. When these
methods are being used, no detector can provide
a warning. These techniques include:
• Pacing - A patrol car drives behind you and
matches your driving speed.
• Vascar/Aircraft - The time it takes a vehicle to
travel a known distance is measured.
Radar Detector Detectors: VG-2,
The Interceptor VG-2 or simply VG-2, is one type of
microwave receiver used by Police to detect signals
radiated by the local oscillator of a radar detector.
Because its purpose is to identify persons driving
with radar detectors, these devices are known as a
“radar detector detector” (RDD).
An RDD is the primary tool used by the police to
identify radar detector equipped vehicles. If caught
in a state or country where detectors are illegal (see
page 18), drivers risk losing their radar detector and
receiving a fine. In addition, instant-on radar is
almost always used in combination with an RDD,
leaving unsuspecting motorists vulnerable to receive
two tickets - one potentially for speeding, the other
for possession of a detector.
Note: Having a radar detector capable of
detecting the VG-2 may alert you to the
presence of a speed trap. The newest tool
Police have to detect radar detectors is called
Spectre. As of this printing. Spectre can detect
the majority of undetectable (VG-2) laser/radar
detectors on the market.
It is the responsibility of the radar detector user to
know and understand the laws in your area
regarding the legality of the use of radar detectors.
