Precautions

Important: The LRD 737 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 737 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.

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 737 is a completely integrated laser/radar detector. It responds to the X-, K-, and Ka-SuperWideband radar guns in use today and also provides front/rear laser 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 737 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 737.

The LRD 737 employs V.C.O. (Voltage Controlled Oscillator) and E.D.I.T. (Electronic Data Interference Terminator) circuitry, giving more reliable performance.

The E.D.I.T. circuitry filters out unwanted microwave signals and prevents certain falsing.

We are certain that you will enjoy the LRD 737, and to ensure that you get the most from its features, please read this Operating Guide carefully before installing and operating the unit.

Feature Highlights

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 737 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 737 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 737 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.

There are two Laser signals: Laser and Laser 2.

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 737 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 737 detects a signal, be on the alert. It is important to exercise caution at all times.

Installation

The LRD 737 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 737 in a location where it will obstruct your driving vision.

???Most vehicles have the top part of the windshield tinted. Mounting the LRD 737 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 laser sensor are located at the rear panel of the unit, (and the rear-looking laser sensor is 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, carefully bend the angled portion of the windshield mounting bracket so that the LRD 737 is parallel to the road surface. Be sure the LRD 737 is mounted so it is free of obstructions from seat backs, rear view mirror, sun visors, or the ceiling of the automobile.

Connecting the Power

The LRD 737 is designed to operate on most 13.8 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 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.

Replacing the Fuse

The cigarette lighter plug contains a 1-ampere fuse to protect it from power surges.

1.To replace the fuse,

unscrew the top of the plug.

2.Remove the fuse and

replace it with the same type.

3.To replace the top, push in

the two metal contacts and twist into place.

Note: Your LRD 737 comes with an extra fuse.

Operation

You are now ready to enjoy the convenience and security of your LRD 737. 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 737, it performs a self-test of all its circuits. This test takes several seconds, during which you will hear the different alarm tones and see all the LEDs. First, you will hear the X-band alarm while the (R)adar, (P)ower and signal strength LEDs light. It is best to adjust the audible alarm during the self-test. Next you???ll hear the K-band, Ka-SuperWideband, Laser, S.W.S., and Laser 2 alarms, each for 1 second, while the (C)ity, (M)ute, (L)aser, S.W.S. and (L)aser (2) LEDs light. (The power LED remains on until you turn off the unit.) When turned on, the LRD737 always returns to its last setting.

After the LRD 737 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.

Memory Retention Feature

The Memory Retention Feature retains the LRD737???s operational settings in memory for at least 2 days without power. When you turn on the LRD737, it will be in the same mode as when you turned it off.

Full Warning

When the LRD 737 detects a radar, laser, or safety warning signal, it emits a distinct warning tone and the corresponding alert LEDs

(R, L/L2, 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, 2 laser systems and Safety Warning System are all different.

Visual Alert Only Operation

You can operate the LRD 737 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 the 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 audible 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 to light, but as signal strength increases, more LEDs light. All three LEDs light when full signal strength is received. Use this meter to judge the distance from the signal source.

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 737 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 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 737 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 737 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 the LRD 737.
