Uniden LRD6299SWS, LRD6399SWS User Manual
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 6299SWS/LRD 6399SWS is a complete
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 6299SWS/LRD 6399SWS 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. You can drive with confidence
when you bring along the LRD 6299SWS/LRD 6399SWS.
The LRD 6299SWS/LRD 6399SWS 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 6299SWS/LRD 6399SWS also uses the new D.R.O. (Dielectric
Resonant Oscillator) and E.D.I.T. (Electronic Data Interference
Terminator) circuitry, giving more reliable performance.
We are certain that you will enjoy the LRD 6299SWS/LRD 6399SWS,
and to ensure that you get the most from its features, please read this
Operating 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 (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 3 radar bands (microwave frequencies):
Xband (10.49 to 10.56GHz), Kband (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 6299SWS/LRD 6399SWS 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 6299SWS/LRD 6399SWS can 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 6299SWS/LRD
6399SWS 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.

Laser
The Laser Speed Detection System, also called LIDAR (for Light
Detection and Ranging), 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 6299SWS/LRD
6399SWS 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).
Note: To be safe, do not ignore any warnings. Although there are other
types of radar signals that may cause interference, when the
LRD 6299SWS/LRD 6399SWS detects a signal, be on the alert.
It is important to exercise caution at all times.

Note: To operate with visual alert only, set the volume control to
the minimum. Remember though, that if the volume control is
turned down and Audio Only operation is selected, the alarm
features are completely disabled.
5. Mute Button — Press the MUTE button to activate the Auto Mute
feature, which produces a full alert level when a signal is first
received, then automatically reduces to half volume for the rest of
the warning.

4. Laser Signal Indicator — A red LED under L lights and blinks to
indicate the presence of a laser signal. A distinct audio alert is also
heard.
5. SWS Signal Indicator — When an early warning hazard or
informational signal is detected, the yellow SWS LED begins to
blink and the amber K-band LED lights. A distinct audio alert is
also heard.
6. Power-On Indicator — A green LED under P lights to indicate
power is being supplied to the unit and the unit is turned on.
7. LED Signal Strength Meter — Four LEDs give an accurate visual
indication of the strength of radar or laser signals.
8. City Mode Indicator — A green LED under C lights to indicate
that you selected City Mode.
9. Auto Mute Indicator — A red LED under M lights to indicate that
you selected the Auto Mute feature.
Note: Every time you turn on the LRD 6299SWS/LRD 6399SWS, a
self-test is performed for all LEDs and Alert tones. You will hear
in-order four distinct tones for the X-, K-, and
Ka-SuperWideband radar bands, as well as for laser.

Installation
The LRD 6299SWS/LRD 6399SWS uses a highly sensitive horn-type
antenna and IR laser sensor to receive radar/laser 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 6299SWS/LRD 6399SWS in a
location where it will obstruct your driving vision.
• Most vehicles have the top part of the windshield tinted. Mounting
the LRD 6299SWS/LRD 6399SWS behind tinted or mirrored glass
may reduce the effectiveness of laser detection by reducing the
amount of laser light received by the 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.
