Color profile: Disabled Composite Default screen 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 6250SWS/LRD6275SWS 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.

SPEED DETECTION IMPORTANT INFORMATION ABOUT YOUR NEW LASER/RADAR DETECTOR Color profile: Disabled Composite Default screen 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 vehicles distance and speed.
Color profile: Disabled Composite Default screen ▼ 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.
Color profile: Disabled Composite Default screen CONTROLS AND FUNCTIONS OF YOUR LASER/RADAR DETECTOR CONTROLS AND FUNCTIONS 1. Clip Release Press the clip release button to remove the LRD 6250SWS/LRD 6275SWS 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.
Color profile: Disabled Composite Default screen LED PANEL D1) D2) Every time you turn on the LRD 6250SWS/ LRD 6275SWS, 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, laser L2 and SWS. D3) D4) D5) X-Band Signal Indicator A green LED lights and blinks to indicate the presence of an X-band radar signal. The blink rate increases as the radar source gets closer.
Color profile: Disabled Composite Default screen INSTALLATION OF YOUR NEW LASER/RADAR DETECTOR INSTALLATION The LRD 6250SWS/LRD 6275SWS 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.
Color profile: Disabled Composite Default screen 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.
Color profile: Disabled Composite Default screen 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.
Color profile: Disabled Composite Default screen 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. 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.
Color profile: Disabled Composite Default screen 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. 12 C:...LRD6250-75SWS-.
Color profile: Disabled Composite Default screen OPERATION OPERATION POWER ON Turn the volume control to switch on the power. When you power up the LRD 6250SWS/LRD 6275SWS, 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 lights. The test also checks the signal meter LEDs.
Color profile: Disabled Composite Default screen MEMORY RETENTION FEATURE The Memory Retention Feature retains the LRD6250SWS/ 6275SWS’s operational settings in memory for at least 2 days without power. When you turn on the LRD 6250SWS/6275SWS, it will be in the same mode as when you turned it off. FULL WARNING When the LRD 6250SWS/LRD 6275SWS detects a radar, laser, or safety warning signal, it emits a distinct warning tone and the corresponding alert LEDs (X, K, Ka, L, SWS or VG2) will light and blink.
Color profile: Disabled Composite Default screen 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 LRD 6250SWS/LRD 6275SWS 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.
Color profile: Disabled Composite Default screen 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.
Color profile: Disabled Composite Default screen 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.
OF YOUR NEW LASER/RADAR DETECTOR CARE & MAINTENANCE Color profile: Disabled Composite Default screen CARE AND MAINTENANCE The LRD 6250SWS/LRD 6275SWS 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 6250SWS/LRD 6275SWS on the windshield when you park your vehicle.
