Precautions

Important: The LRD 6699SWS was not designed to help you

disobey the law. Safe drivers always obey the posted
speed limit and legal driving methods at all times.

Federal and Local Regulations
The FCC passed the Communications Act in 1934 to give all citizens the

right to receive any type of radio transmission. The same radio
frequencies used by police radar are also used by other devices, such as
automatic door openers, burglar alarms, and some amateur radio
equipment. Since the LRD 6699SWS is just a radio receiver tuned to a
specific portion of the public radio spectrum, it is protected under this act.

Some local, state, and federal regulations may prohibit the use of this
detection device. Please check with authorities regarding the use of this
device before operating it.

Operation Notice

Safety Warning Systems

You have purchased the newest technology designed for Radar, Laser and
Safety Warning System detection and alert. You should be aware that
Safety Warning transmitters (the device that alerts your detector for
safety warning alerts) will be available for use throughout the United
States. However, these transmitters may not be used in all areas.

While this detector is designed to warn you of road hazards, it is not
designed as a substitute for safe, attentive driving procedures. Drivers are
reminded to remain alert for road hazards at all times.

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 6699SWS 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. And, the built-in Safety
Warning System (SWS™) is capable of detecting hazardous warning
signals transmitted on the K-band.

The LRD 6699SWS 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 6699SWS.

The LRD 6699SWS 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 6699SWS
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 6699SWS, 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 three radar bands (microwave
frequencies): X-band (10.49 to 10.56GHz), K-band (24.04 to 24.26 GHz),
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 6699SWS 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 6699SWS 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 6699SWS 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

etection and Ranging), uses a laser gun that emits infrared light pulses

D
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 6699SWS 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 6699SWS detects a signal, be on the alert. It is important to
exercise caution at all times.
