XTR-435 Owner’s Manual
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 manual,
but is not operating optimally, please refer to
the troubleshooting guide below.
PROBLEM: No display or audio.
• Check the fuse in the plug; replace if
necessary with a 2 amp, 3AG type.
• Check the fuse for lighter socket; replace if
necessary.
• Make sure the lighter socket is clean.
PROBLEM: Unit alarms when vehicle hits
bumps.
• Check for a loose lighter socket; tighten and
clean.
• Check the connections at both ends of the
power cord. Substitute another cord to
determine if the cord is defective. Return the
defective cord to the factory.
PROBLEM: Audio alerts are not loud enough.
• Cancel Auto Quiet Mode or City Mode.
• Check audio level setting. (see page 8)
If difficulties occur which cannot be solved by
information in this Troubleshooting Guide,
please call Whistler Customer Service at
1-800-531-0004 or visit our FAQ page at www.

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.
ARE DETECTORS LEGAL?
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.
The Federal Highway Administration (FHWA)
passed a nationwide regulation, effective
January 1994, which prohibited radar and laser
detector use in vehicles over 10,000 lbs.

This device complies with part 15 of the FCC
Rules. Operation is subject to the following two
conditions:
(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.

Radar Facts
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 only alarm if an officer
is transmitting on any one of the above radar
bands.
FCC INFORMATION
19
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
transmission.
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 +/- 10nm.

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 police measure the time
it takes your vehicle to travel a known distance.
Radar Detector Detectors: VG-2,
Spectre
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 potential for speeding, and the
other for possession of a detector.
SPEED MONITORING
21
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. 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.
