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 6199SWS 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 6199SWS 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 6199SWS.
The LRD 6199SWS 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 6199SWS
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 6199SWS, 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 6199SWS 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 6199SWS 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 6199SWS 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.
2

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 6199SWS 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 6199SWS detects a signal, be on the alert. It is important to
exercise caution at all times.

Installation
The LRD 6199SWS 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 6199SWS in a location where it
will obstruct your driving vision.
•Most vehicles have the top part of the windshield tinted. Mounting
the LRD 6199SWS 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.

Adjusting the Windshield Mounting Clip
1. The metal portion of the bracket locks into the plastic portion at
three different positions. These positions can be used for vehicles
with 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, bend the angled portion of the
windshield mounting bracket so that the LRD 6199SWS is parallel
to the road surface. Be sure the LRD 6199SWS 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 6199SWS:
1. Insert the windshield clip into the LRD 6199SWS.
2. Place the bracket and the LRD 6199SWS in the proper location on
the windshield of your vehicle, and press the suction cups firmly
against the windshield.

Connecting the Power
The LRD6199SWS is designed to operate on most 12 VDC negative
ground vehicle electrical systems. The power cord provided with the unit
has a cigarette lighter socket plug at one end and a small connector at the
other.
1. Insert the small connector into the jack on the side of the unit.
2. Insert the other end into the cigarette lighter socket of your
vehicle.
When installing the power cord, make sure that:
•The socket is clean to allow proper contact.
•The power cord does not block the antenna area on the back of the
unit.
Your unit also comes with ten power cord mounting clips. You can use
these clips to attach the power cord to the window frame or other parts of
the vehicle, keeping it neat and out of the way. Use the double-sided
foam tape squares to attach each clip. Slip the power cord into the clip to
hold it securely in place.

Operation
You are now ready to enjoy the convenience and security of your
LRD 6199SWS. Please read this section of the Operating Guide carefully
to familiarize yourself with the basic operation of this unit.
Power On
Turn the Volume control to switch on the power. When you power up the
LRD 6199SWS, it performs a self-test of all its circuits. This test takes
about 5 seconds, during which you will hear the different alarm tones and
see all the LEDs. First, you will hear the X-band alarm for 2 seconds
while the X-band indicator, City, and Mute LEDs light. The test also
checks the signal meter LEDs. It is best to adjust the audible alarm during
the self-test. Next you’ll hear the K-band/SWS alarm,
Ka-SuperWideband alarm, and Laser alarm, each for 1 second, while the
corresponding signal indicator LED lights. (The power LED remains on
until you turn off the unit.) The LRD 6199SWS always turns on in Full
Alert Mode.
Note: Any previous selection of City Mode, Audio Alert Only Mode, or
Mute Mode will be reset.
After the LRD 6199SWS confirms proper operation, the alert tones and
all LEDs, except the green Power LED, turn off. If the Power LED does
not light, check the cigarette lighter socket connection. If the unit turns on
and off intermittently, or the alert tone sounds too often for no reason,
check the power cord connection at both ends to be sure it is not loose.
Volume Control
Adjust the Volume control
to a comfortable alarm tone
level for your vehicle. The
volume level does not have
any effect on the unit’s
sensitivity.

Full Warning
When the LRD 6199SWS detects a radar, laser, or safety warning signal,
it emits a distinct warning tone and the corresponding alert LEDs
(X, K, Ka, L, or SWS) will light and blink. 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, all lighted LEDs will dim. 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.)
Note: The audio alert tones for the 3 radar bands and laser are all
different.

Visual Alert Only Operation
You can operate the LRD 6199SWS in 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. Be sure
that the Audio Alert Only indicator is off.
Auto Mute Operation
Press the Mute button to activate the Auto Mute feature.
When the Mute indicator 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 half volume for the duration of the
warning.

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.
The City indicator lights.
In City Mode, the combination of visual and audio alert tones varies
based on the strength of the received signal.
Note: If you use both Audio Only Alert and City modes, you won’t
receive an alert until you are very close to the radar source.

LED Signal Strength Meter in City Mode
The LED signal strength meter gives you instant information about the
strength of the signal being detected. A weak signal causes the first LED

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 6199SWS is capable of detecting the SWS signal broadcast on the
K-band by either law enforcement or local departments of transportation.
The yellow SWS LED blinks and the amber K-band LED lights, 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.

Care and Maintenance
The LRD 6199SWS is designed to give you years of trouble-free service.
There are no user-serviceable parts inside, and, except for the fuse, no
maintenance is required. To keep your detector in new condition, follow
these important suggestions:
•Never leave the LRD 6199SWS on the windshield when you park
your vehicle. The temperature in the vehicle in summer can reach
levels above what is considered to be safe for this unit.
•To make you less susceptible to break-in and theft, remove the unit
from your windshield when you leave your vehicle.
•Do not expose the unit to moisture. Rain, dew, road splash, or other
liquids can damage the internal components and reduce sensitivity of
