Bracket Slot

The mounting bracket fits into 

this slot.

When a signal is detected, the display will show the band type, 

City/Highway setting, and signal strength. If the LRD350 detects 

a laser, the display shows L. (Laser is used in close proximity and 

has no signal associated with it.)

Install the LRD350 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 

 button.

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 

volume dial away from you until it clicks. The unit is now turned 

on.
The LED cycles through the display in this order: X - K - Ka - 

Laser, then signal strength except for Laser (L). 
Once the cycle is complete, the detector turns to standby 

mode.

The LRD350 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 L). The signal strength (1 through 5) also 

displays as applicable. If there is a specific alert code, that is 

also displayed.

The LRD350 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. 

•  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 LRD350 operates in three 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 for the X band 

so it can pick up weaker signals. (X, K, Ka, Laser)

•  City I. Similar to City mode, but no X band is detected. (K, Ka, 

Laser)
