LED DISPLAY
When a signal is detected, the display will show the band
type, City/Highway setting, and signal strength. If the
LRD450 detects a laser, the display shows L.
INSTALLATION AND TURN UP
Install the LRD450 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 button.
Dashboard
1. Place the unit on the dashboard so that it has a clear,
level view of the road.
The unit cannot be readjusted aer nal installaon.
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 LCD cycles through the display in this order: X - K - Ka -
Laser, then signal strength 1- 5 except for Laser (L).
Once the cycle is complete, the detector turns to standby
mode.

DETECTION
The LRD450 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 frequency
strength (1 thorough 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
automac doors at a supermarket or even another
car’s cruise control; these devices operate in the
same frequency ranges as radar guns.
BANDS
The LRD450 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 (press and hold
CITY) 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 sensive 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 LRD450 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 -

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 LRD450 recognizes the following bands/
frequencies used by radar guns:
BAND FREQUENCY
X10.525 GHz
K24.150 GHz
Ka 33.400 - 36.000 GHz
Laser 800 nm - 1100 nm
RADAR DETECTOR DETECTORS
(RDDS)
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 LRD450 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 LRD450 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.
Replace if necessary.
The unit alarms
when the vehicle
hits bumps.
Check the connections. Be sure
they are all secure.
The unit alarms
briefly in the same
location but no radar
source was in view.
There may be a motion sensor or
house alarm in use within range.
The detector did not
alert when a police
car was in view.
The officer may not have radar/
laser units turned on.
