Safety Warning System™
In communities where transmitters are located,
the Safety Warning System
displays over 60 text
messages. When Safety Radar is detected the audio
alert is geiger counter-like.
Safety Warning System Text
Example: Poor - Road - Surface.
Not all areas have Safety Warning System
POP™ Mode Alerts
Mode travels on regular radar bandwith,
there is no particular alert for POP
Mode alerts will be displayed as a regular radar alert.
Speed Radar Audio / Visual Alerts
When X, K or Ka is detected the band ID and signal
strength is displayed. The audio alert is continuous
and has a geiger counter-like pattern. The faster the
beep the closer or stronger the radar source.
Laser Audio / Visual Alerts
When a laser signal is detected the word “Laser” and
signal strength is displayed, the audio alert is continuous
for a minimum of 3 seconds. Example:
The more “|||” the closer the laser source.
Pulse (or 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, your Whistler
detector sounds an urgent 3-second audio warning
and the display shows PULSE (like the picture above.
After the 3-second pulse alert, the standard alert pat-
tern continues for as long as the signal is present.
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 in option select
mode 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 VG-2 Alert X, K, and Ka band signals cannot
be received (Reference page 19 & 20 for VG-2 information).
When two or more signals are received at the same
time, the alert priority is:
3. Speed Radar
4. Safety Radar
If X band is alerting, then suddenly VG-2 is detected,
the VG-2 warning will override the X band alert.
All user features can be reset to factory settings.
•Unplug Power Cord from unit.
•Press and hold Power and Quiet.
•Plug Power Cord into unit.
•Wait for 2 beeps.
•Release Power and Quiet buttons.
Unit is now reset.
Default factory settings are:
Audio to level (4).
2. Display reads Highway.
3. Dim/Dark Mode to full illumination of display.
4. Auto Quiet Mode OFF.
5. VG-2 Detection Mode OFF.
6. Combo ON.

PROBLEM: No display or audio.
• Check fuse in Whistler plug; replace if necessary with a 2
amp 3AG type.
• Check fuse for lighter socket; replace if necessary.
• Make sure lighter socket is clean.
PROBLEM: Unit alarms when vehicle hits bumps.
• Check for loose lighter socket; tighten and clean.
• Check connections at both ends of power cord. Substitute
another cord to determine if cord is defective. Return
defective cord to the factory.
PROBLEM: Unit alarms when using vehicle electrical
(brakes, power mirrors/windows,
turn signals, horn, etc.).
• Vehicle’s electrical system, including battery and alternator, may
have electrical noise. Install a filter capacitor
(470mfd. 25 volt
or larger capacitance value)
on the back of the lighter socket.
PROBLEM: Unit gives laser alert when accelerating.
• Possible bad or low quality distributor cap. Replace with
high quality cap.
PROBLEM: Audio alerts are not loud enough.
• Cancel Auto Quiet Mode or City Mode.
• Check audio level setting
(see page 8 & 9).

ARE DETECTORS LEGAL?
In Most States YES!
Laser/radar detectors are legal in every state (with
the exception of Virginia and Washington, D.C., which
have local regulations restricting the use of radar
receivers in any vehicle) when used in automobiles or
light trucks (under 10,000 lbs.).
Concerning trucks over 10,000 lbs., the Federal
Highway Administration (FHWA) issued a regulation,
effective January, 1994 which prohibits radar and laser
detector use in these types of vehicles nationally. Prior
to the FHWA regulation, laws existed in the state of
New York restricting the use of radar detectors in trucks
over 18,000 lbs. and in Illinois in trucks over 26,000 lbs.
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 units exterior.
Radar Detector Detectors (VG-2)
The Interceptor VG-2, or simply VG-2, is a microwave
eceiver 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,
the VG-2 is known as a “radar detector detector”.
The VG-2 is the primar
y tool used by the police to
identify radar detector equipped vehicles. If caught,
in a state where detectors are illegal, (see page 19),
drivers risk losing their radar detector and receiving a
fine. In addition, instant-on radar is almost always used
in combination with a VG-2, leaving unsuspecting motorists
vulnerable to receiving two tickets - one potentially
for speeding, the other for possession of a detector.
Having a radar detector capable of detecting the
VG-2 may alert you to the presence of a speed trap. For
more information on speed monitoring technologies,
please visit our FAQ page on our website:
NOTE: It is the responsibility of the individual radar
detector owner to know and understand the laws in your
area regarding the legality of the use of radar detectors.

A radar gun operates by transmitting radio waves at
certain frequencies which reflect off objects and are
then 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 (Federal Communications
Commission) 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.
Mode is a feature on some newer radar guns
operating on K or Ka bands. When the gun is in POP
Mode and activated, a brief burst of energy, less that
1/10 of a second, is transmitted and the vehicles’s
speed is quickly acquired. A detector without POP
Mode detection capability cannot respond to this
brief transmission. This detector has the power to
report this new gun where other detectors cannot!
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 transmission
can cover more than a four-lane highway at a distance
of 1,000 feet, compared with a laser transmission
which covers about 3 feet at the same distance. For
best protection, keep these points in mind:
• Because you vehicle’s license plate or headlights
are the laser gun’s primary targets, mounting your
Whistler detector on the dashboard can improve
laser detection at short range.
• Do not follow closely behind any vehicle you cannot
see through. If you can’t see past a vehicle ahead
of you, chances are your detector won’t either.
• The receiving range of your laser detector will not
be the same as a radar detector. 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.
I II III •LT1 20-20 •Ultra Lyte
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
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.
2. Include with your unit the following information,
• Your name and street address
(for shipping via
, a daytime telephone number and email
address, if applicable.
• A detailed description of the problem (e.g., “Unit
performs self-test but does not respond to radar”).
• A copy of your dated store receipt or bill of sale.
3. Be certain your unit is returned with its serial number.
For reference, please write your units serial number
in the following space: s/n_______________.
Units without serial numbers are not covered under warranty.
IMPORTANT: To validate that your unit is within
the warranty period, make sure you keep a copy
