16

OPERATION

Traffic Flow Sensor Rejection (TFSR)
Field Disturbance Sensor Rejection (FDSR)

Recently many new products that operate on police
radar frequencies have been causing nuisance alerts
to radar detectors. These radar based sensors are
installed alongside the Highway and more recently
on vehicles used as lane change assist / blind spot
detectors / collision avoidance systems. TFSR when
turned ON is designed to eliminate alerts from
specific Traffic Flow sensors. FDSR when turned
ON is designed to identify all radar based collision
avoidance systems that operate within the same band
as police radar and provide a brief, less intrusive alert
to keep you informed and aware.
A signal strength indicator will help determine
your proximity to the source without the continued
annoyance of audio.

Filter Modes

There are times when a radar detector in another
vehicle can emit a frequency which can cause your
detector to falsely alert. The Filter Modes allow you to
select the level needed for your area to minimize the
occurrences of these false alerts. Filter 1 is the factory
default setting and should provide adequate filtering
for most conditions. If you experience excessive alerts
due to radar detectors in other vehicles, increase the
Filter level. See Option Select Mode chart at the back
of this user guide to change the filter settings.

17

OPERATION

Speed Selectable Auto Quiet

Traveling below the speed selected in option mode
will engage Auto Quiet mode.
NOTE: Enter Option mode to set Speed Selective
Auto Quiet. (0-40MPH / 0-65KMH)

Speed Selectable Filter Mode

Traveling below the speed selected in option mode
will apply the maximum Filter.
NOTE: Enter Option Mode to set Speed Selectable
Filter. (0-40MPH / 0-65KMH)

VG-2 Mode

See Option Select Mode to turn this feature on/
off. When a VG-2 signal is detected, the VG-2 alert
is sounded and the display flashes “VG-2”. After 3
seconds the audio is canceled and the display no
longer flashes. This cycle is repeated if the VG-2 signal
is detected again .

During the period a VG-2 signal is detected, a
radar signal cannot be detected.

However, because the VG-2 alert has confirmed that
a patrol car is nearby, you are already aware of the
potential for speed monitoring and can adjust your
speed accordingly. Laser detection is not affected
while a VG-2 signal is detected.

18

OPERATION

Laser Signature ID (LSID)

Identifies the Laser gun’s pulse rate or PPS (Pulses per
Second) that is transmitted by the speed laser gun.
LSID may also be used to identify other forms of laser
sources such as LACC (Laser Assisted Cruise Control)
systems found in some high-end vehicles. If the Laser
PPS information displayed is due to another source
such as local airports or LACC, LSID allows you to lock
out this rate from giving you the continuous audio
alert during this and any new encounter of the same
rate.

To lock out a PPS, press the Quiet button during the
Laser alert. This will place an * on the screen beside
the PPS rate and lock out this signature ID. Any new
encounter with the same Laser Signature ID will
provide the display information and two quick beeps.

Caution: Do not lock out a PPS rate if it is close to
known speed laser guns.

Segmented Selectable Laser Receiver

The laser validation windows are separated into
segments allowing for customization.
Segment Pulse Rate
Laser Area 1: 20Hz to 950Hz (.02 - .95)
Laser Area 2: 2600Hz to 3200Hz (2.6 - 3.2)
Laser Area 3: 3800Hz to 4200Hz (3.8 - 4.2)

19

OPERATION

Laser Area 1 covers the traditional laser guns used in
North America. Laser Area 2 and 3 cover laser guns
recently approved for use in North America. You can
change the selection from yes to no individually in
option mode. If a laser within a group is not used in
your area, you may shut off that group (change the
selection from Y to N while in Option Select Mode) by
pressing the DARK or QUIET buttons.

POP™ Mode Alerts

Because POP™ Mode radar utilizes the same K or Ka
band frequencies, POP™ Mode Alerts will initially be
displayed as POP K or POP Ka then switch to band
and signal strength.

Safety Warning System™ (SWS™)

In communities where transmitters are located,
the Safety Warning System™ provides over 60 text
messages. When SWS™ is detected the audio alert is
geiger counter-like.
Safety Warning System Text Message

Example: HIGHWAY HAZARD

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

Example: A laser warning will override a radar alert.

20

OPERATION

Getting a Satellite Lock

Powering up, the unit will begin its search for satellites.
During this time, the unit will flash the satellite icon on
the display. Please allow several minutes for the unit to
lock onto the satellites.

Satellite no lockSatellite lock

NOTE: Driving while initially searching for satellites
will take longer than if you are stationary. Acquiring
satellites takes much longer the first time.

Red Light/Speed Camera Alerts

When approaching a known camera, the unit will
provide the type of alert (Red Light Camera, Traffic
Camera, Speed Camera, or User Location). Example:
the display will show TRF CAM then count down
the distance to the camera. Once past the camera
location, the unit will provide a beep-beep audio tone
and the word PASS will be shown on the display.

21

OPERATION

Manual Entry (Waypoint)

Once GPS has a lock, you can save a special location
(i.e., a new red light camera or even a “trap”). The unit
will store 1000 user locations.

In Most States YES.

Laser-Radar detectors are legal in every state (except
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.). The Federal Highway Administration
(FHWA) issued a regulation, effective January, 1994
which prohibits radar and laser detector use in vehicles
over 10,000 lbs. Prior to the FHWA regulation, laws
existed in New York restricting the use of radar detectors
in trucks over 18,000 lbs. and in Illinois in trucks over
26,000 lbs.

Notice to Drivers in California and Minnesota:
State law prohibits drivers in California and Minnesota
from using suction mounts on their windshields while
operating motor vehicles. Other dashboard mounting
options should be used. (See California Vehicle Code
Section 26708(a); Minnesota Statutes 2005, Section

169.71). Check local laws for compliance.

RADAR/LASER ALERTS

Radar Alerts

When X, K or Ka 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.

Laser Audio/Visual Alerts

When a laser signal is detected the word “LSR” and
the corresponding laser pulse rate is displayed, the
audio alert is continuous for a minimum of 3 seconds.
“LSR 238”

Pulse Protection

Pulse (or instant-on) radar 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.

Display Shows:

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.

POP™ Mode

POP™ Mode is a feature on some radar guns operating
on K and Ka bands. When 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.

SPEED MONITORING

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 can’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 wave length of 905nm

+/- 50nm including but not limited to the following:

• Ultra Lyte

• LTI 20-20

• LTI TruSpeed® S

• Laser Ally

• Pro Laser™ I II III

• Laser Atlanta® Stealth Mode

SPEED MONITORING

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.

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.
This laser/radar detector receives signals from 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: Your radar detector is designed to alarm if an
officer is transmitting on any one of the above radar
bands.

SPEED MONITORING

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, 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.

38

SPEED MONITORING

NOTE: 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 individual radar detector
user to know and understand the laws in your area
regarding the legality of the use of radar detectors.
