DOT MATRIX DISPLAY
The LRD750 contains a dot matrix display. When a signal is
detected, the display shows the band type and signal
strength in an increasing bar format. If the LRD750 detects
a laser, the display shows LASER.
INSTALLATION AND TURN UP
Install the LRD750 on the front windshield or on the
dashboard. For best performance, position the detector as
low as possible in the center of the front windshield. Be
sure the unit’s view of the road, either to the front or the
back, is clear.
INSTALLATION
WINDSHIELD
1. Clean the windshield and the rubber cups of the
mounting bracket. Attach the rubber cups to the
bracket.
2. Push the bracket firmly onto the windshield.
3. Slide the unit onto the bracket.
4. Gently adjust the bracket angle if needed.
Do not use the detector to adjust the bracket angle.
5. Plug the power cord into the detector.
6. Plug the cigarette lighter adapter into the vehicle’s
cigarette lighter.
You can remove the detector by pressing the
Eject
key.
Dashboard
1. Place the unit on the dashboard so that it has a clear,
level view of the road.
The unit cannot be readjusted after final installation.
2. Remove the backing from one side of the hook and loop
fastener tape.
3. Place that fastener tape on the dashboard where you
want the unit.
4. Attach the other piece of the fastener tape to the
bottom of the unit and attach the unit to the dashboard
fastener tape.
You can remove the unit as needed.
5. Plug the power cord into the detector.
6. Plug the cigarette lighter adapter into the vehicle’s
cigarette lighter.
TURN UP
Once the detector is installed and the car is turned on, turn
the Power/Volume dial away from you until it clicks. The
unit is now turned on.
The unit cycles through the display in this order: X - K - Ka -
Laser, then signal strength except for Laser (L). Voice
announces each band.
Once the cycle is complete, the detector turns to standby
mode.
DETECTION
The LRD750 detects emissions from radar guns and sounds
an audio alert for the driver. The detector determines
which band range the signal is from and displays that
frequency type on the display (X, K, Ka, or Laser). The
frequency strength (1 thorough 5) also displays in an
increasing bar format.
False signals can come from other devices such as the
automatic doors at a supermarket or even another
car’s cruise control; these devices operate in the
same frequency ranges as radar guns.
BANDS
The LRD750 recognizes:
• X Band: This band was the first frequency band assigned
to police radar. It operated on a lower frequency
(10.525GHz) with a higher power output.
• K Band: This band is the most common frequency used
in radar detectors (24.150). Its relatively small
wavelength gives it a clocking distance of about 1/4 mile
although, depending on the environment, it can detect
up to 2 miles. Turn on the K band filter through the
menus to filter out weaker K band frequencies and
reduce false readings.
• Ka Band: Over the years, the Ka band incorporated the
Ka-Band, the Ka Wide-Band, and the Ka Super Wide-
Band. Most photo radars (also known as stop light
cameras) use this band.
POP™ is a single-pulse Doppler radar feature on some
K and Ka band radar guns. This type of radar gun is
a very sensitive receiver; limit POP detect mode to
highway and rural driving.
• Laser: Police use the laser’s narrower light pulses for
speed detection as it is more accurate and faster. Laser
beams are more detectable after they have bounced off
their target and begin to disperse on the return trip.
MODES
The LRD750 operates in two modes:
• Highway. Provides audio and visual alerts any time all
bands and laser are detected. Recommended for
highway or rural driving. (X, K, Ka, Laser)
• City. Provides audio and visual alerts any time all bands
and laser are detected. Provides a stronger signal so it
can pick up weaker transmissions. (K, Ka, Laser)
VOICE ANNOUNCE
The LRD750 has a voice feature that tells you the unit
status as it changes. For example, if the unit picks up K
band transmissions, it announces “K band.” Turn this
feature on and off through the menus.
OPERATION
After installing your radar detector, you can set it to your
own specifications through the keys and the menu.
