INTRODUCTION
Welcome to the world of sophisticated, early warning laser/radar
detection. You have purchased one of the most advanced laser/radar
detectors available. The LRD 767 / LRD 777 is a completely integrated
laser/radar detector. It responds to the X, K, and Ka-SuperWideband
radar guns in use today and also provides 360 detection of the latest
speed monitoring system — the laser gun. The built-in Safety
Warning System (SWS™) is capable of detecting a hazardous
warning signal transmitted on the K-band.
The LRD 767 / LRD 777 provides distinct visual and audio alerts to
warn you of the presence of X, K, and Ka-SuperWideband radar
signals as well as IR laser signals and Safety Warning System. You can
drive with confidence when you bring along the LRD 767 / LRD 777.
The LRD 767 / LRD 777 employs Super Stalker Technology (SST), a
state-of-the-art electronic system designed to make this radar
detector invisible to all current VG-2 radar detector detectors.
The LRD 767/LRD 777 will also warn you of VG-2 use.
The LRD 767 / LRD 777 includes electromagnetic compass
sensors to its circuitry and enables you to stay on course with this
digital navigator.
We are certain that you will enjoy the LRD 767 / LRD 777, and to
ensure that you get the most from its features, please read this
Reference Guide carefully before installing and operating the unit.

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 (Ra
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

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.
LASER
▼
The Laser Speed Detection System, also called LIDAR (for Li
Detection and R
anging), uses a laser gun that emits infrared light
ght
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).

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.
