SPEED DETECTION SYSTEMS
A speed detection device (often called a radar gun) sends out
either a microwave signal or beam of light. When this signal
reaches its target, part of the signal is reflected or bounced back
toward the emitting gun. The time required for the signal to leave
the gun, bounce off an object, and return is used to determine a
vehicle’s distance and speed.
▼
RADAR
Radar (Radio Detection and Ranging) is a microwave system for
detecting the speed of moving objects by reflected pulses of high
frequency radio waves. There are three radar bands
(microwave frequencies): X band (10.49 to 10.56GHz), K band
(24.04 to 24.26GHz), and the “superwide” Ka band (33.4 GHz to
36 GHz).
The X band was the first used for traffic, followed by the K band
which is harder to detect (most instant-on radar is K band). The
Ka band was introduced in 1987, and widened to Ka SuperWideband
in 1990 by the FCC. The LRD 767/LRD 777 monitors all current
radar bands including the entire Ka SuperWideband.
The radar beam is cone shaped — the narrower the beam, the
greater the resolution. A moving vehicle reflects radar signals
back towards the radar gun. The LRD 767/LRD 777can detect the
signals emitted by radar guns, and it will sound an audio alarm
and flash a warning indicator. For continuously transmitting
radar, use the LRD 767/LRD 777 to get accurate detection from a
safe distance. Weak signals cause the audio and visual alarms to
sound intermittently, but as the signal gets stronger (the closer
you get to the radar gun), both alarms increase in intensity.
Instant-on transmitters fire a short radar pulse beam at a vehicle
and instantly read its speed. When detected at a distance, you will
hear a few beeps and see the strength meter begin to light.
Instant-On radar signals are the most difficult to detect at a safe
distance because they are transmitted only when directed at you
or at a vehicle directly ahead of you.

SPEED DETECTION
IMPORTANT INFORMATION ABOUT YOUR NEW LASER/RADAR DETECTOR

▼
LASER
The Laser Speed Detection System, also called LIDAR (for Li
ght
Detection and R
anging), uses a laser gun that emits infrared light
pulses just outside the spectrum of visible light. Each reflected
pulse measures the speed of the object coming toward or going
away from the laser gun.
Unlike radar, the laser gun emits a very narrow beam of light, so
it can pinpoint a speeding car within traffic. The infrared beam
spreads out, but slowly and over a longer distance than a
radar signal.
The laser gun can acquire a speed reading as quickly as 0.3
seconds, sometimes less. However, since it isn’t easy to accurately
aim at and hit a moving target, an operator often moves the laser
gun in several directions to get a reading. So laser signals
are emitted continuously for a few seconds for each
speed measurement.
The LRD 767/LRD 777 can detect these light pulses from as far
away as 1.5 miles, which is about four times the effective
range of a laser gun (2,000 feet), and about ten times its
average operating range (500-800 feet).
5
To be safe, do not
ignore any warnings.
Although there are
other types of radar
signals that may
cause interference,
when the
LRD 767/LRD 777
detects a signal, be
on the alert. It is
important to exercise
caution at all times.

INSTALLATION
The LRD 767/LRD777 uses a highly sensitive horn-type antenna
and IR laser sensor to receive laser/radar signals. Its sensitivity
and range depend on the method of installation and the direction
of the antenna/sensor in relation to the signal source. The
inherent nature of radar waves makes them reflect off metallic
surfaces. This is why these waves are so useful for measuring the
speed of a vehicle. The IR laser light may reflect only from shiny
surfaces. Both radar waves and IR laser light will, however, pass
through plastic or glass.
Before you decide where to put your radar detector, please keep in
mind these two important factors:
•
For safety, do not mount the LRD 767/LRD 777 in a location
where it will obstruct your driving vision.
•
Most vehicles have the top part of the windshield tinted.
Mounting the LRD 767/LRD 777 behind tinted or mirrored
glass may reduce the effectiveness of laser detection by
reducing the amount of laser light received by the dectector.

INSTALLATION
OF YOUR NEW LASER/RADAR DETECTOR

HELPFUL TIPS
The antenna and the forward looking sensor are located
behind the rear panel of the unit, (and the rear- and
side-looking sensors are located on top of the unit), directly
behind the mode selection keys. The antenna and sensors
should not be obstructed by metal or metallic surfaces
and should be pointed at the horizon for accurate
long-range detection.
•
Do not mount the unit behind the windshield wiper blades,
radio antenna, tinted glass area, or mirrored glass. Be sure
the unit is free from obstruction by seat backs, rear view
mirror, sun visors, or the ceiling of the automobile.
•
Do not mount the unit in front of the heater or
defroster vents.
•
Do not leave the unit in direct sunlight or in the glove
compartment of a closed car for long periods of time, as
extreme changes in temperature may cause internal damage.
Also, removing the unit from the windshield makes you less
susceptible to break-in and theft.

INSTALLATION

ADJUSTING THE WINDSHIELD MOUNTING CLIP
1) The metal portion of the bracket locks into the plastic
portion at two different positions. These positions can be used
for vehicles with two different vertical angles of their
windshields. The back position can be used for vehicles with
windshields that are slanted back.
2) For optimum laser detection, gently bend the angled portion
of the windshield mounting bracket so that the LRD 767/
LRD 777 is parallel to the road surface. Be sure the
LRD 767/LRD 777 is mounted so it is free of obstructions
from seat backs, rear view mirror, sun visors, or the ceiling
of the automobile. There must be a clear 360 line of sight
to the outside of the vehicle.
To mount the LRD 767/LRD 777:
1) Press the button on top of the radar and insert the
windshield clip into the LRD 767/LRD 777. The metal
portion of the bracket locks in to the plastic portion.
2) Place the bracket and the LRD 767/LRD 777 in the proper
location on the windshield of your vehicle, and press the
suction cups firmly against the windshield.

operational settings in memory for at least 2 days without power.
When you turn on the LRD 767/LRD 777, it will be in the same
mode as when you turned it off.
FULL WARNING
When the LRD 767/LRD 777 detects a radar, laser, VG-2 or safety
warning signal, it emits a distinct warning tone and the
corresponding visual messages will light. The blink rate of the LEDs
increases and the signal strength meter LEDs light successively as
the signal source comes closer.
AUDIO ALERT ONLY OPERATION
Press the audio button for Audio Alert Only operation.
When Audio Alert Only is selected, the visual alert and signal
strength meter are disabled. In this mode, the display panel will
dim. There are four levels for the display panel brightness control.
You can control the brightness by pressing the
audio button repeatedly.
Press the
audio button again for the Full Alert (audio and
visual) Mode. Do not set the Volume control at minimum when in
Audio Alert Only because there will be no alert.
14

VISUAL ALERT ONLY OPERATION
You can operate the LRD767/LRD777in Visual Alert Only by
setting the
volume control at the minimum position in Full
Alert Mode. At this setting you can barely hear the audio alert
in a quiet environment.
AUTO MUTE OPERATION
Press the mute button to activate the Auto Mute feature.
When the Mute is selected, the unit is in Auto Mute Mode.
In this mode you hear the full audio alert when a signal is
first received. The audio alert automatically reduces to a
chirp for the duration of the warning.
15

To operate with
visual alert only, set
the volume control to
the minimum.
Remember though,
if the volume control
is turned down and
Audio Only operation
is selected, the alarm
features are
completely disabled.
OPERATION

CITY OPERATION
In highly populated areas, you may encounter many devices that
use the same frequencies as radar signals, such as motion
detectors, automatic doors, and intrusion alarms. These devices
may trigger an alert called “falsing.”
To filter most of the weaker signals and get the most accurate
radar signal recognition, press
city to turn on the City Mode.
In City Mode, the combination of visual and audio alert tones
varies based on the strength of the received signal.
16
If you use both the
Audio Only Alert and
City modes, you won’t
receive an audio alert
until you are very
close to the radar
source.

SIGNAL STRENGTH METER
The signal strength meter shown in the display panel gives you
instant information about the strength of the signal being detected.
A weak signal causes the first bar to light, but as signal strength
increases, more bars light. All six bars for radar and three bars for
laser light when full signal strength is received. Use this meter to
judge the distance from the signal source.
*NOTE : In Audio only mode the signal strength meter
will not be displayed.
<Examples>
SAFETY WARNING SYSTEM OPERATION
The Safety Warning System (SWS™) is a new communication
system that will provide an early warning when a road hazard
exists. The LRD 767/LRD 777 is capable of detecting the SWS
signal broadcast on the K-band by either law enforcement or
local departments of transportation.The corresponding message
from 64 SWS warning messages is scrolled from the right to the
left of the display panel. while an audible alert sounds.
When this alert sounds, you should tune to local radio traffic
reports or prepare to slow down or stop your vehicle because
you could be approaching an accident, bad road conditions
caused by weather, or road crews or construction.
