Stay Alert Feature

The Stay Alert Feature is designed to test a driver’s
alertness. To engage (when unit is not alarming) :

• Press and hold City for approximately 2
seconds. Release button during or immediately
after the alert is given. Display shows:                     
–XTR-325 only: The “H“or “C“ will flash
Within 30-60 seconds two beeps are sounded; to

show alertness, the driver must press either the

City, Volume, or Quiet buttons within 3-5 seconds. If
a button is not pressed within 3-5 seconds, the
cycle is repeated.

If a button was not pressed within 3-5 seconds
alarm sounds and the display shows:   
All LEDs flash for XTR-325
• Press Power to exit.
WARNING!!! Stay Alert is NOT intended as a

substitute for adequate rest. You should NOT operate
a vehicle if you are drowsy. During extended periods of
vehicle operation, you should take frequent breaks.
Improper reliance on the Stay Alert feature may result
in vehicle damage, personal injury or death. NEVER
OPERATE A VEHICLE IF YOU ARE DROWSY.

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.
XTR-325 displays an “S.”
Note: Not all areas have Safety Warning System

POP

™ 

Mode Alerts

Because POP

™ 

Mode travels on regular radar 

bandwidth, there is no particular alert for POP

™

Mode transmissions. POP

™ 

Mode alerts will be 

displayed as a regular radar alert.

Speed Radar Audio/Visual Alerts

When X, K, Ka, or Ku is detected, the band ID
and signal strength are displayed. The audio
alert is continuous and has a geiger counter-like 
pattern. The faster the beep, the closer or
stronger the radar source.
Note: Geiger not available when custom tones

Laser Audio/Visual Alerts

When a laser signal is detected, the audio alert is 
continuous for a minimum of 3 seconds. 

• The Displays Shows:
The more “|||”, the closer the laser source.

XTR-325 displays an “L”

Pulse Protection

®

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:    
XTR-325 displays an “P”
After the 3-second pulse alert, the standard alert
pattern 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

When a VG-2 signal is detected, the detector ‘hides’ its
own radiated signal and becomes undetectable by
the VG-2.

Once VG-2 is detected, 

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
Example: If X band is alerting, then suddenly a VG-

2 signal is detected, the VG-2 warning will override

the X band alert.

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 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 using vehicle
electrical accessories (brakes, power mirrors,
power windows, turn signals, horn, etc.)
when unit is connected to the power cord.

• 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 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:  Audio alerts are not loud enough.

• Cancel Auto Quiet Mode or City Mode.
• Check audio level setting (see page 8).

PROBLEM:  Unit turns itself off

• See battery saver feature on page 12

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.whistlergroup.com/faq-detectors.asp,
before returning your unit for service.

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 this unit will not be used for an
extended period of time. Damage caused by
leaky or improperly charged batteries are not
covered under warranty. Check with the battery
manufacturer about the specific battery warranty.

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.

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 (Federal Communications
Commission) permits operation of traffic radar
guns at X Band (10.500 - 10.550 GHz), K Band
(24.050 - 24.250 GHz), Ka Band (33.400 - 36.000
GHz) and Ku Band (13.425 - 13.475 GHz).
Note:  A radar detector will not alarm if an

POP™ Mode

POP

™

Mode is a feature on some newer 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. 

Total Band Protection™ PLUS Ku

Complete Band Coverage that detects laser,
radar including Ku, VG-2 and safety 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 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 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.

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:
•  P

acciin

ng

g - A patrol car drives behind you and 

matches your driving speed.

• V

travel a known distance is measured.

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 it 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 a RDD, 
leaving unsuspecting motorists vulnerable to receive
two tickets - one potentially for speeding, the other
for possession of a detector.
