Controls & Features
Display Color
Radar Sensitivity
This feature automatically turns off GT-7 after a set
period of time to save unnecessary drain on your
battery. This is especially useful if your vehicle has a
constant-power ignition. See the Settings &
Preferences section for details on how to customize
the AutoPower feature.
Your detector screen can be displayed with copper,
blue, green or red accents to match the dashboard
lighting of various vehicles. See the Programming
section for details on how to change the display color.
The SEN button allows you to select your preferred
radar sensitivity: Highway, Auto or Auto No X. In
general, Beltronics recommends Auto for everyday
The AutoLock feature analyzes (over time) the source
of radar signals by location and frequency. This
allows GT-7 to determine if a signal is a real threat or a
false one. If it determines that the signal is an
automatic door opener, motion sensor, etc., it
automatically locks out this source at this particular
location. A “Stored” message will appear on the
display when a signal has been automatically locked
out. If you prefer, you can turn the AutoLock feature
off. See the Programming section for details.
In this setting, GT-7 will detect all radar signals on all
bands at maximum range.
NOTE: When AutoPower is ON, the display will go dark
after the vehicle has been sitting still for 30 minutes, to
save screen life. The screen will turn back on
automatically once your vehicle reaches a speed of 10
To adjust GT-7 to your preferred audio level for alerts,
simply press and hold VOLUME + or –. The audio will
increase/decrease while it is depressed. Once you
reach the desired audio level, simply release the
button. GT-7 will retain this setting in its memory,
even if the system is turned off.
The MUTE button allows you to silence the audio
during an alert. Simply press the button during the
alert. Once the radar encounter has passed, the mute
will disengage, and the audio will return to your
pre-set level. You can also silence an alert by pressing
the SmartCord MUTE button.
Your GT-7 also includes the patented AutoMute
feature. Once GT-7 alerts you to a radar encounter at
your selected volume level, it automatically reduces
the volume more than 50%. This keeps you informed
without the annoyance of a continuous full-volume
alert. If you prefer, you can turn the AutoMute feature
off. See the Programming section for details.
If AutoMute has already reduced the volume for one
alert and a higher-priority band is detected, GT-7 will
sound an alert at your set volume for the second
band before adjusting the volume back down to the
AutoMute level.
User Mode
In this setting, GT-7 will continuously analyze all
incoming signals and intelligently adjust the
sensitivity circuits, providing long-range warning
with minimal false alarms.
Auto No X
Auto No X works the same as Auto mode; however, X
band is completely turned off.
Display Brightness
GT-7’s display brightness is automatically adjusted to
suit ambient lighting conditions in your car. (The light
sensor is located inside the controller, so the display
may dim momentarily when you access the buttons.)
If you prefer, you can press the BRT button to set a
fixed brightness level:
WARNING: Do not use GT-7 in Auto No X unless you are
absolutely certain that there are no traffic radar guns
using X band in your area.
TrueLock/Locking Out False Alerts
GT-7 is equipped with a TrueLock GPS Filter to lock
out and store in its memory false alerts. To lock out a
false alert (X band, K band or laser only), press the
MUTE button on the detector or the SmartCord three
times during an alert. Pressing the first time will
silence the audio. Pressing a second time will
generate a prompt on the display that will read
“Lockout?” Press a third time to confirm you want to
lock this signal out by location and frequency. A
“Stored” message will be displayed.

NOTE: If you select Dark mode, the display will not
provide any indication that it is on. Therefore, only
audible alerts will notify you of detected signals.
Once a signal has been stored, GT-7 will reject the
signal the next time you approach this area and will
display the locked-out alert.
Speed Display
GT-7 displays your current speed just to the right of
the Over-Speed Alert setting (or posted speed limit
for your current location, if connected to ESCORT
Live). If you prefer, you can turn off the speed display
feature (see Programming section for details). If
speed display is OFF, GT-7 will simply display your
battery voltage in this location.

Marking Locations
The MRK button allows you to mark a specific location
and label it for future reference. Once marked, GT-7
will provide an alert when you reach this area again.
Speed trap
GT-7 offers two unique user modes:
NOTE: AutoLock typically needs to encounter the exact
frequency in the same location approximately three
times to lock it out. Since some door openers are turned
on and off routinely, some variations may occur. When
AutoLock is on, GT-7 will also unlearn signals to protect
you from locking out real threats. If a particular signal is
no longer present at a location that was previously
locked out, GT-7 will unlock that signal.
For details on how to turn the GPS Filter off, refer to
the Programming section.
Speed display OFF: Battery voltage
In this mode, you can access and customize units
(English or metric) and display color only. All other
preferences are set to the factory defaults. To view all
settings and preferences, you must switch back to
Advanced mode.
NOTE: When the GPS Filter is set to OFF, you do not have
access to GT-7’s other GPS-enabled features (e.g.,
DEFENDER Database alerts, marking locations, etc.).
Controls & Features
GT-7 gives an advanced warning of upcoming
markers at the following distances:
• Red light cameras: 250 ft or 10 seconds
• Red light & speed cameras: 250 ft or 10 seconds
• Speed cameras: 500 ft when traveling below 55
mph; 1,000 ft when traveling above 55 mph
Speed traps: 0.3 mi or approximately 1,584 ft
Other: 500 ft when traveling below 55 mph; 1,000 ft
when traveling above 55 mph
To mark a location, press the MRK button. The display
will read “Mark?” Press MRK again to bring up a menu
of markers to choose from. Press VOLUME + or – to
scroll through the markers, then press MRK to select
the marker you wish to use at this location. The
display will read “Marked!”
NOTE: When a location is marked the first time, you must
travel at least 1 mile away from that location to receive
an alert when you return to the area.
To unmark a location, touch the MRK button when
you are receiving a marked-location alert. The display
will read “Unmark?” Touch the MRK button again to
confirm. The display will read “Unmarked!” To
customize the types of markers you want to be able
to set and receive, see the Settings & Preferences
Over-Speed Alert
With GT-7, you can set the Over-Speed Alert to notify
you when you are traveling over a specified speed
(factory default is 70 mph; see Programming for
details). When you travel above the speed threshold
you have set, the background display for your current
speed will turn red to alert you that you have
exceeded the specified speed.
Alert Tones
Voice Alerts
GT-7’s factory default for alert tones is the Beltronics
Standard mode, in which GT-7 uses a Geiger countertype sound to indicate the signal strength and type
of radar signal being encountered. When you
encounter radar, a distinct audible alert will sound
and will increase as the signal gets stronger. This
allows you to judge the distance from the signal
source without taking your eyes off of the road. Each
band has a distinct tone for easy identification:
X band
K band
Ka band
GT-7 provides digital voice announcements for alerts
and selection feedback. If you prefer, you can turn off
the voice feature. See the Programming section for
details. .
Signal-Strength Meter
GT-7 offers four different settings for displaying alerts:
The Standard option provides information on a
single radar signal. When GT-7 detects radar, it
displays the band of the radar (X, K or Ka) and a bar
graph of the signal’s strength. When laser is detected,
the display will simply read “Laser.” If there are
multiple signals present, GT-7 will determine which
one is the most important threat to display.

brap tone
double-brap tone
solid brap tone
solid brap tone
If you prefer, you can change your alert tone settings
to Mild mode, which offers softer, simpler alert tones
that are less obtrusive to the driving experience:
The Tech option is an advanced display for
experienced detector users. In this mode, it will
display the actual numeric radar frequency being
received. Even long-time detector users will require
some time to get familiar with this new level of
information about detected signals. To use GT-7 in
Tech meter mode, you must select it in Programming.
X band, K band,
Ka band and Pop = Doorbell chime
Low signal strength = Double chime
High signal strength = Triple chime
If alert remains in area
more than 15 seconds = Single chime
(as a reminder)
The Threat option is also designed for the advanced
detector user. In this mode, GT-7 simultaneously
tracks up to four radar signals (Ka band, X band, K
band and X band) and shows each signal along with a
bar graph of its strength. Threat meter mode can help
you spot a change in your normal driving
environment (e.g., a traffic radar unit being operated
in an area where there are normally other signals
present). To use GT-7 in Threat meter mode, you must
select it in Programming.
Laser = Solid brap tone (Since laser
signals are a possible threat no matter how weak, GT-7
alerts you to all laser signals with a full laser alert.)
See the Programming section for details on switching
your alert tones.
Cruise Alert
The Cruise Alert feature allows you to modify your
alert tones when traveling below a specified speed
(factory default is 20 mph; see Programming for
details). For all alerts received while traveling below
the specified speed, GT-7 will sound a simple doublebeep alert.
ExpertMeter simultaneously tracks up to four radar
signals: Ka band, X band, K band and X band. It
shows each signal along with a bar graph of its
strength. ExpertMeter can help you spot a change in
your normal driving environment (e.g., a traffic radar
unit being operated in an area where there are
normally other signals present).
In this mode, Basic messages replace actual bands
and signal strengths or frequencies. “Caution” is
used when an alert is received while you are traveling
below your current Cruise Alert setting (or posted
speed limit for current location, when connected to
ESCORT Live). “Slow Down” is displayed when an alert
is received while you are traveling above the current
Cruise Alert setting (or posted speed limit for current
location, when connected to ESCORT Live).
NOTE: GT-7’s selectable bands feature allows you to
customize which bands are monitored. For details on
modifying your band detection, see the Programming
section. For details on the various radar/laser bands and
how they work, see the Understanding Your Detector

Understanding Your Detector
Interpreting Alerts
Although GT-7 has a comprehensive warning system,
only experience will teach you what to expect from
your detector and how to interpret what it tells you.
The specific type of radar being used,
the type of transmission (continuous or instant-on)
and the location of the radar source affect the alerts
you receive.
The following examples will give you an introduction
to understanding your detector’s warning system for
radar and laser alerts.
Detector begins to sound slowly; rate of alert
increases until it becomes a solid tone. The
signal meter ramps accordingly.
You are approaching a continuous radar source
aimed in your direction.
Detector emits short alerts for a few seconds
then falls silent, only to briefly alert and fall
silent again.
An instant-on radar source is being used ahead
of you and out of your view.
Detector suddenly sounds a continuous tone
for the appropriate band received.
An instant-on radar or laser source is being used
nearby. This kind of alert requires immediate
Detector sends a brief laser alert.
Laser is being used in the area. Because laser is
inherently difficult to detect, any laser alert may
indicate a source very close by.
Detector receives weak signals. Signals may be
a little stronger as you pass large, roadside
objects. Signals increase in frequency.
How Radar Works
Traffic radar, which consists of microwaves, travels in
straight lines and is easily reflected by objects such
as cars, trucks, and even guardrails and overpasses.
Radar works by directing its microwave beam down
the road. As your vehicle travels into range, the
microwave beam bounces off your car, and the radar
antenna looks for the reflections. Using the Doppler
principle, the radar equipment then calculates your
speed by comparing the frequency of the reflection
of your car to the original frequency of the beam
sent out.
Traffic radar has limitations, the most significant of
these being that it typically can monitor only one
target at a time. If there is more than one vehicle
within range, it is up to the radar operator to decide
which target is producing the strongest reflection.
Since the strength of the reflection is affected by both
the size of the vehicle and its proximity to the
antenna, it is difficult for the radar operator to
determine if the signal is from a sports car nearby or a
semi truck several hundred feet away.
Radar range also depends on the power of the radar
equipment itself. The strength of the radar unit’s
beam diminishes with distance. The farther the radar
has to travel, the less energy it has for speed
A moving patrol car with continuous radar is
overtaking you from behind. Because these
signals are reflected (reflections are increased by
large objects), they may or may not eventually
melt into a solid point, even when the patrol car
is directly behind you.
Detector alerts slowly for a while then abruptly
jumps to a strong alert.
You are approaching a radar unit concealed by a
hill or an obstructed curve.
Detector alerts intermittently. Rate and
strength of alerts may be consistent or vary
A patrol car is traveling in front of you with a
radar source aimed forward. Because signals are
sometimes reflected off of large objects and
sometimes not, the alerts may seem inconsistent.
Detector alerts intermittently; rate and
strength of signal increases with each alert.
A patrol car is approaching from the other
direction, sampling traffic with instant-on radar.
Such alerts should be taken seriously.
Detector gives an X band alert intermittently.
You are driving through an area populated with
radar motion sensors (e.g., door openers or
burglar alarms). Since these transmitters are
usually contained inside buildings or aimed
toward or away from you, they are typically not
as strong or lasting as a real radar encounter.
Because intrusion alarms and motion sensors often
operate on the same frequency as X and K band
radar, your detector will occasionally receive nonpolice radar signals. Since these X band transmitters
are usually contained inside of a building or aimed
toward the ground, they will generally produce much
weaker readings than will a true radar encounter. As
you become familiar with the sources
of these pseudo alarms in your daily
driving, they will serve as
confirmation that the device’s radar
detection abilities are fully
How POP Works
POP works by transmitting an extremely short burst,
within the allocated band, to identify speeding
vehicles in traffic. Once the target is identified, or
“popped,” the gun is then turned to its normal
operating mode to provide a vehicle tracking history
(required by law).
NOTE: According to radar gun manufacturers, tickets
should not be issued in pop mode.
How Laser Works
Laser speed detection is actually light detection and
ranging (LIDAR). Laser guns project a beam of
invisible infrared light. The signal is a series of very
short infrared light energy pulses that move in a
straight line, reflecting off your car and returning to
the gun. Laser uses these light pulses to measure
the distance to a vehicle. Speed is then calculated by
measuring how quickly these pulses are reflected,
given the known speed of light.
Laser is a newer technology whose use is not as
widespread as conventional radar; therefore, you may
not encounter it on a daily basis. And unlike radar
detection, laser is not prone to false alarms. Because
laser transmits a much narrower beam than does
radar, it is much more accurate in its ability to
distinguish between targets and is also more difficult
to detect. As a result, even the briefest laser alert
should be taken seriously.
There are limitations to laser, however. Laser is much
more sensitive to weather conditions than radar,
and a laser gun’s range will be decreased by anything
affecting visibility, such as rain, fog or smoke. A
laser gun cannot operate through glass, and it must
be stationary to get an accurate reading. Because
laser must have a clear line of sight and is subject to
cosine error (an inaccuracy that increases as the
angle between the gun and the vehicle increases),
police typically use laser equipment parallel to the
road or from an overpass. Laser can be used day or
How TSR Works
GT-7 includes a new boost in anti-falsing software to
eliminate excessive alerts from erroneous X and K
band sources, such as traffic flow monitoring systems.
These systems, which are becoming more widely
used in several countries, generate K band signals to
measure the flow of traffic on a given road.
Unfortunately, most detectors see this as a
real threat and will alert you to it
unnecessarily. Our new proprietary software, TSR,
intelligently sorts, ranks and rejects these types of
false alarms automatically. The result is ultimate
protection without excessive false alarms.
CAUTION: Overconfidence in an unfamiliar area can be
dangerous. Likewise, if an alert in a commonly
traveled area is suddenly stronger or on a different band
than usual, speed radar may be set up nearby.
Understanding Your Detector
How Red Light Cameras Work
How GPS Works
Red light cameras use three basic things: a camera, a
device to trigger the camera and a computer. An
intersection may have more than one camera to
monitor traffic from multiple directions. The trigger is
typically a series of wires buried just beneath the
surface of the road. These wires are separated by a
pre-set distance to create a magnetic field or
induction loop. Once a vehicle is in the intersection,
the loop or circuit becomes closed and alerts the
computer to take a picture.
Developed by the U.S. military,
the global positioning system (GPS) is
made up of 24 orbiting satellites. There
are at least four satellites visible at any given
time every day. A GPS receiver is designed to locate
and receive data from four of these satellites. These
data include the distance to your location from each
of the satellites. Once the distance from each satellite
is known, the receiver can calculate and pinpoint your
exact location.
Detector beeps briefly at the same location every day,
but no radar source is in sight.
An X band motion sensor or intrusion alarm is located
within range of your route.
Detector did not alert when a police car was in view.
VASCAR (Visual Average Speed Computer and
Recorder), a stopwatch method of speed detection,
may be in use.
Officer may not have radar or laser unit turned on.
In some states, tickets are issued to the car’s owner,
no matter who’s actually driving. In this case, the red
light camera only needs to photograph the vehicle’s
rear license plate. In other states, the actual driver is
responsible for paying the ticket. In this case, the
system needs a second camera in front of the car to
get a shot of the driver’s face.
Detector’s audible alerts become softer after the first
few alerts.
Detector is in AutoMute mode. See “AutoMute” in the
Settings & Preferences section for details.

How Speed Cameras Work
There are several types of fixed position speed
cameras used, including radar, laser, induction-loop
and photo-based. Radar and laser based cameras are
typically mounted near the road and transmit a short
range signal across the lanes monitored. Since this
signal is transmitted across the road instead of down
the road like with many handheld systems, detecting
them in time is critical.
Check all connections.
Another technology used is an induction loop system.
This type of system utilizes wires buried just beneath
the surface of the road to trigger a computer that
calculates speed between the two points. Photo
based systems take two sets of pictures of all passing
vehicles between two separate fixed locations. Both
sets of photographs are date and time stamped,
which enables the system to calculate average speed
between the two locations.
Fixed speed cameras can also be set up to monitor
one to four lanes of traffic in the same direction. To
achieve this, a sensor is installed in each lane, and a
wide angle camera lens is used to photograph the
vehicle that is speeding.
