a laser, the display shows L. (Laser is used in close proximity and
has no signal associated with it.)

INSTALLATION AND TURN UP

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.

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

Dashboard

1. Place the unit on the dashboard so that it has a clear, level
view of the road.

The unit cannot be readjusted aer nal installaon.

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
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.

DETECTION

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.

False signals can come from other devices such as the

automac doors at a supermarket or even another
car’s cruise control; these devices operate in the
same frequency ranges as radar guns.

BANDS

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.

MODES

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)

OPERATION

SETUP

After installing your radar detector, you can set it to your own
specifications.

• Mute/Auto Mute. When an audio alert sounds, pressing

MUTE lets you turn off the audio alarm. Press and hold
MUTE to set Auto Mute to ON to reduce the audio

alarm by 50% automatically after 3 seconds during an
alert.

• Dim. Change the brightness of the display. (Default ­Bright)

• Set City, City I, or Highway

– City mode delays all X band audio alerts until the signal is

at level 2.
– City I mode does not recognize X band transmissions.
– Highway mode recognizes all bands and is recommended

for highway driving. (Default)

MONITORING SPEED

A radar gun transmits radio waves at certain frequencies that
bounce off objects and return to the radar gun’s receivers. The

radar gun then calculates the speed of the object. The LRD350
recognizes the following bands/frequencies used by radar guns:

BAND FREQUENCY

X 10.525 GHz

K 24.150 GHz

Ka 33.400 - 36.000 GHz

Laser 800 nm - 1100 nm

RADAR DETECTOR DETECTORS

(RDD)

Radar detectors are illegal in some states. Law enforcement
officers use special equipment to detect signals radiated by
radar detectors. If they are in a state where radar detectors are
illegal and the officer detects a vehicle using a radar detector,
the operator of that vehicle could lose the radar detector and
be fined.

The LRD350 is designed to be invisible to signals from the
Spectre l, Spectre lV, and VG-2 RDDs.

CARE AND MAINTENANCE

Use common sense and your LRD350 will provide trouble-free
service. Please keep the following tips in mind:

• Don’t leave your unit on the dashboard during summer
months. Interior heat may exceed safe operating levels.

• Do not spray cleaners or other liquids on the unit.
Remove the unit when you are using these liquids.

• Do not use abrasive cleansers on the unit’s exterior.

TROUBLESHOOTING

IF... TRY THIS...

No display or audio. Check the fuse in the plug.

The unit alarms
when the vehicle
hits bumps.

The unit alarms
briefly in the same
location but no radar
source was in view.

The detector did not
alert when a police
car was in view.

Replace if necessary.

Check the connections. Be sure
they are all secure.

There may be a motion sensor or
house alarm in use within range.

The officer may not have radar/
laser units turned on.
