LED DISPLAY
When a signal is detected, the display will show the band type,
City/Highway setting, and signal strength. If the DFR1 detects 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 DFR1 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 after final installation.
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 DFR1 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
automatic doors at a supermarket or even another
car’s cruise control; these devices operate in the
same frequency ranges as radar guns.
BANDS
The DFR1 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 DFR1 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)
