LED DISPLAY

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

type, City/Highway setting, and signal strength. If the DFR3

detects a laser, the display shows L.

INSTALLATION AND TURN UP

Install the DFR3 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 aﬅer ﬁnal 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 DFR3 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 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 DFR3 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 sensi°ve 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 DFR3 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.

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 3.

–

City I mode does not recognize X band
