Care And Maintenance
During the summer months, avoid prolonged expo-
sure to direct sunlight by removing your unit from the
dash when your vehicle is parked for an extended peri-
od of time. Do not spray water, cleaners or
polishes directly onto the unit. The spray may pene-
trate through the openings and damage the unit. Also,
do not use any abrasive cleaners on the unit’s exterior.
Troubleshooting
Your Whistler detector is expertly engineered and
designed to exacting quality standards to provide you
with reliable, trouble-free operation. If your unit has been
correctly installed following the guidelines in this manu-
al, but is not operating optimally, please refer to the trou-
bleshooting guide on next page.
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 equipment, electrical
accessories (brakes, power mirrors/windows, directionals, horn, etc.),
or when accelerating.
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: Audio alerts are not loud enough.
Cancel Auto Quiet Mode or City Mode.
Check audio level setting (see page 9).
PROBLEM: No X band signals.
Cancel City 2.
PROBLEM: Unit gives laser alert when accelerating.
Possible bad or low quality distributor cap. Replace with high
quality cap.
If difficulties occur which cannot be solved by informa-
tion in this Troubleshooting Guide, please call Whistler
Customer Service at 1-800-531-0004 before returning
your unit for service.
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 the state of Illinois in trucks over 26,000 lbs.

This device complies with part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) This device many not
cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause unde-
sired operation.
IMPORTANT
FCC requirements state that changes or modifications not
expressly approved by Whistler could void the user’s authority to
operate the equipment.
Radar Facts
A radar gun operates by transmitting radio waves at certain frequen-
cies which reflect off objects and are then picked up by the radar
gun’s receiving section. When a radar beam reflects off a moving tar-
get, 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 transmit-
ting on any one of the above radar bands.
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 vehi-
cles. 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 dis-
tance.
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.

Other Speed Detection Systems
Several techniques other than radar or laser are used to measure
vehicle speeds. When these methods are being used, no detec-
tor 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 oscillator of
a radar detector. Because its purpose is to identify persons driv-
ing with radar detectors, the VG-2 is known as a “radar detector
detector”.
