Mounting

Bracket Slot

The mounting bracket fits into

this slot.

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.

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.

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.

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

key.

1.  Place the unit on the dashboard so that it has a clear,

level view of the road.

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.

5.  Plug the power cord into the detector.
6.  Plug the cigarette lighter adapter into the vehicle’s

cigarette lighter.

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.

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.

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.

•  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.

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)

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.

After installing your radar detector, you can set it to your

own specifications through the keys and the menu.

•  Turn alert audio off (voice - Mute On)

during alert audio. Mute cancelled 10

seconds after alert ends.

•  In Menus, return to the previous menu

option.

•  Change brightness from BRIGHT to DIM to

DARK. Voice announces all changes.

•  In Menus, toggle the displayed setting.
