TO YOUR NEW LASER/RADAR DETECTOR INTRODUCTION 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.
INCLUDED WITH YOUR RADAR DETECTOR INTRODUCTION The industry’s most To get the most from your laser/radar detector, please read this Reference Guide thoroughly.
IMPORTANT INFORMATION ABOUT YOUR NEW LASER/RADAR DETECTOR SPEED DETECTION 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.
▼ LASER The Laser Speed Detection System, also called LIDAR (for Li ght 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. The laser gun can acquire a speed reading as quickly as 0.3 seconds, sometimes less.
CONTROLS AND FUNCTIONS OF YOUR LASER/RADAR DETECTOR CONTROLS AND FUNCTIONS 1. Clip Release — Press the clip release button to remove the LRD 767/LRD 777 from the windshield mounting clip. 2. Rear and Side Laser Detector Lense — For rear and side detection of laser signals. 3. Press the city button to help reduce X-band false alarms while driving in the city. When you turn on the City Mode, the City indicator turns on. While driving on highways, turn off the City Mode for long-range detection.
DISPLAY PANEL The display panel indicates the driving direction and each mode of the operational conditions when no signal is engaged. Every time you turn on the LRD 767/LRD 777, a self test is performed for all visual and audio alerts. You will hear, in-order, four distinct tones for the X, K, and Ka-SuperWideband radar bands, as well as for laser, laser L2, VG-2 and SWS.
INSTALLATION OF YOUR NEW LASER/RADAR DETECTOR 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.
HELPFUL TIPS • 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.
ADJUSTING THE WINDSHIELD MOUNTING CLIP 1) The metal portion of the bracket locks into the plastic portion at two different positions. These positions can be used for vehicles with two 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, gently bend the angled portion of the windshield mounting bracket so that the LRD 767/ LRD 777 is parallel to the road surface.
CONNECTING THE POWER 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. 11 INSTALLATION Use only a Uniden supplied power cord or its replacement. The LRD 767/LRD 777 is designed to operate on most 12 VDC negative ground vehicle electrical systems.
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.
OPERATION OPERATION POWER ON DEMONSTRATION OPERATION OF YOUR NEW LASER/RADAR DETECTOR You are now ready to enjoy the convenience and security of your LRD 767/LRD 777. Please read this section of the Reference Guide carefully to familiarize yourself with the basic operation of this unit. 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 LRD 767/LRD 777’s operational settings in memory for at least 2 days without power. When you turn on the LRD 767/LRD 777, it will be in the same mode as when you turned it off. FULL WARNING When the LRD 767/LRD 777 detects a radar, laser, VG-2 or safety warning signal, it emits a distinct warning tone and the corresponding visual messages will light.
VISUAL ALERT ONLY OPERATION WARNING To operate with visual alert only, set the volume control to the minimum. Remember though, if the volume control is turned down and Audio Only operation is selected, the alarm features are completely disabled. You can operate the LRD767/LRD777in 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.
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. If you use both the Audio Only Alert and City modes, you won’t receive an audio alert until you are very close to the radar source.
SIGNAL STRENGTH METER The signal strength meter shown in the display panel gives you instant information about the strength of the signal being detected. A weak signal causes the first bar to light, but as signal strength increases, more bars light. All six bars for radar and three bars for laser light when full signal strength is received. Use this meter to judge the distance from the signal source. X K K A L A S E R * NOTE : In Audio only mode the signal strength meter will not be displayed.
OF YOUR NEW LASER/RADAR DETECTOR CARE & MAINTENANCE VOICE ALERT (LRD 777 ONLY) When each function is activated by pressing a control button, the LRD 777 gives the following voice messages: – By the city button : City Mode, Highway Mode – By the audio button : Display Dim, Display Dimmer, Audio Only, Display On – By the mute button : Mute On, Mute On, Mute Off. * NOTE : The second “Mute On” confirms that the voice muting is activated.
