INTRODUCTION
Dear Whistler Owner,
Technology has changed dramatically in 30 years and
Whistler has weathered the changes in style. The 1790SE
30th anniversary edition was developed with all the technical
know-how of those 30 years. We started with a proven
detection circuitry with All BandTM and added top-of-the-line
features such as:
Memo-record up to 90 seconds
Digital Compass-provides cardinal points and direction
in 5 degree increments.
Real Voice®-allows you to keep your eyes on the road
Whistler’s exclusive Safe Driving System-incorporates
the Safety Warning System (SWS), keeping you informed
of road hazards as well as our unique Stay Alert system,
it tests your alertness on long solo trips
Vehicle Battery Saver and Monitor system-battery saver
turns the detector off if you forget and the monitor
momentarily displays the vehicle’s battery voltage
Even though the 1790SE is packed full of features, it is still
very easy to use. To fully utilize the unit to its potential, we
recommend reading this entire manual.
NOTE: Compass must be calibrated before use! See
“Compass Calibration Set-up” section.
Enjoy the Whistler 1790SE and please drive safely.
Sincerely,
THE WHISTLER GROUP

Mounting Guidelines
•Mount the unit as low and level as possible near the center
of the windshield. Unit must be level for compass to func-
tion properly.
•Donot mountyourunitbehindwipers, ornaments, mirrored
sunscreens, etc.These obstructions have metal surfaceswhich
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
owner’smanualsuppliedwith your vehicle todetermine ifyour
windshield has this coating.
•Avoid placing unit in direct contact with windshield.
•Toreducethepossibilityoftheft,concealyourunitwhennot
in use.
Windshield Mounting
•Install the two suction cups and rubber bumper onto the
bracket by fitting them into their holes.
•Press the suction cups onto the windshield at the location
you have chosen. IMPORTANT: Some newer cars have a
plastic safety coating on the inside of the windshield. The
suction cups may leave permanent marks on this type of
surface. To find out if your vehicle has this type of wind-
shield, check the owner’s manual or ask your dealer. We
recommend that you do not leave the suction cup bracket
on the window in direct sunlight. If the detector is
removed, this may cause blistering of the dash in some
vehicles.

Compass Calibration Set-up
The unit will need to be calibrated in order for the com-
pass to provide accurate readings. To calibrate the unit,
perform the following procedure:
1. Mount the unit level in the center of the vehicle’s wind-
shield in which it will be used. Make sure there are no
other magnetic sources near the detector (i.e., speaker).
2. Select a large clear area (parking lot or field) without any
power lines.
3. While parked, press both volume buttons simultaneous-
ly until unit displays:
4. Drive vehicle slowly in two complete circles. If
calibration does not automatically finish press both volume
buttons simultaneously to complete calibration. The unit
will beep twice and display:
Note: If 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.

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.

SPEED MONITORING TECHNOLOGIES
27
ARE DETECTORS LEGAL?
26
In Most States YES!
Laser detectors are completely legal in every state when
used in automobiles or light trucks (under 10,000 lbs.).
Similarly, when used in automobiles or light trucks, radar
detectors are legal in almost every state. Exceptions are
Virginia and Washington, D.C., which have local regulations
restricting the use of radar receivers in any vehicle.
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.
Radar Facts
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).
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 spe-
cific vehicle out of a line of traffic and determine its speed.
The advantage of laser over radar in terms of target identifi-
cation 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 6 feet at the same distance.
For best protection, keep these points in mind:
• Because your 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.

WARRANTY INFORMATIONSPEED MONITORING TECHNOLOGIES
28
Consumer Warranty
The 1790SE Whistler detector is warranted to the original
purchaser for a period of three years from the date of original
purchase against all defects in materials and workmanship.
This limited warranty is void if the unit is abused, modi-
fied, installed improperly, if the housing has been
removed, or if the serial number is missing. There are no
express warranties covering this product other than those set
forth in this warranty. All express or implied warranties for this
product are limited to three years. Whistler is not liable for
damages arising from the use, misuse, or operation of this
product.
Service Under Warranty
During the warranty period, defective units will be repaired or
replaced (with the same or a comparable model), at Whistler’s
option, without charge to the purchaser when returned pre-
paid, with dated proof of purchaseto theaddress below. Units
returned without dated proof of purchase will be handled as
described in section “Service Out Of Warranty.” Due to the
specialized equipment necessary for testing a radar/laser
receiver, there are no authorized service stations for Whistler
brand detectors other than the factory.
When returning a unit for service under warranty, please
follow these instructions:
1. Ship the unit in the original carton or in a suitable sturdy
equivalent, fully insured, with return receipt requested, and
shipping charges prepaid to:
Whistler Repair Dept.
1201 North Dixieland Rd.
Rogers, AR. 72756
Other Speed Detection Systems
Several techniques other than radar or laser are used to meas-
ure 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 a microwave receiver
used by police to detect signals radiated by the local oscilla-
tor of a radar detector. Because its purpose is to identify per-
sons driving with radar detectors, the VG-2 is known as a
“radar detector detector”.
The VG-2 is the primary tool used by the police to identify
radar detector equipped vehicles. If caught, in a state where
detectors are illegal, (see page 26), 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, leav-
ing 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.

nologies, visit our FAQ page at
