Mounting and Powering the RL100
Mounting Instructions
To help ensure that your RL100 functions properly and
offers maximum protection, please follow these mounting
instructions:
1. Clean the area of the windshield where the unit will
be mounted.*
2. Attach the supplied Windshield Mounting Bracket to
your car’s windshield by firmly pressing the suction cups
in the bracket to the windshield.
a. Mount the bracket as low as possible near
the center of the windshield.
b. Do not mount the unit behind wipers or any
metal obstructions.
3. Slide the RL100 unit itself on to the bracket to complete
the mounting.
4. Level the radar detector, if necessary, by carefully
bending the Windshield Mounting Bracket.
*IMPORTANT NOTE: Some windshields include a metallic coating that can
significantly affect reception of radar signals. Consult with your dealer or
check your vehicle’s owner‘s manual to determine if your windshield has
such a coating.
Power Connection
1. Plug the small end of the supplied Power Cord into the
Power Input Jack on the side of the radar detector.
2. Plug the large end of the Power Cord into your vehicle’s
cigarette lighter socket or other 12V outlet.
3. Switch on the RL100 by turning the Power On/Volume
Control Wheel located on left side of the unit.
No power? See Troubleshooting Guide on page 16.

Quick Start
(using factory default settings)
Once your K40 RL100 has been mounted and had the power
connected, you may begin using immediately by following
these steps:
1. Switch on the RL100 – Turn the Power On/Volume
Control Wheel on the side of the unit.
2. Wait for Test Scan to complete – The radar detector
will announce(voice) and display(screen) K40 SCAN then
go through a “wake up sequence” lasting approximately
5 seconds.
a. You will hear and see all bands tested. Adjust the
volume during this test.
b. Upon completion of the sequence scan, the screen
will display HIGHWAY .
c. After finding available satellites, the unit will announce
“GPS Connected” then display GPS .
3. You’re ready to drive! – The RL100 will now display
filter setting, your speed and direction of travel. For
example, if you are driving West at 57 mph and the filter
is on Highway setting, the display will show
H W 57
Please read the entire Owner’s Manual to fully understand
all of the RL100’s operations and functions.

Receiving Alerts
The K40 RL100 provides a combination of audio and visual
alerts to warn you when radar and laser signals are detected.
Radar Alert Sequence
The RL100 detects every kind of FCC approved police radar.
When a signal is identified:
•A voice alerts which band was detected. (This assumes the
factory default “Voice ON” setting has not been changed.)
•A series of beeps indicates the strength of the signal. Each
band has its own distinctive beep. (Volume reduces
automatically after 5 seconds.)
•The display will provide you band and strength information.
Radar Alert Examples:
You are driving 45 mph and a low K-Band is detected.
Visual Alert: K 2 45
Audio Alert: Voice announces “K-Band” followed
by slow beeps.
As you approach the source, you slow to 40 mph and
the signal becomes stronger:
Visual Alert: K 8 40
Audio Alert: Beeping is faster due to stronger signal.
Radar source strength: low medium strong
Display reading: 123 456 789
Audio alert beeps: slowly rapidly
6

Laser Alert Sequence
When the RL100 detects a laser signal:
•A voice alerts announces “Laser.” (This assumes the factory
default “Voice ON” setting has not been changed.)
•You then hear a distinctive audio tone. (Volume reduces
automatically after 5 seconds.)
•Display indicates laser has been detected and reports
your speed.
•NOTE: Unlike radar, signal strength from laser remains
constant.
Laser Alert Example:
You are driving 55 mph and laser is detected.
Visual Alert: LASER 55
Audio Alert: Voice announces “Laser” followed by
distinctive audio tone.
Alerts from non-police signals
Your RL100 is sensitive enough to detect signals generated
by non-police equipment, such as bank security systems.
To learn how to deal with these signals, please read about
FILTER options (page 8) and Quiet RideTM (page 9).

Quiet RideTM
The RL100’s exclusive Quiet RideTM Function will automati-
cally silence all radar and laser alerts when traveling under
a specific speed of your choice between 20-65 MPH.
The factory default setting for Quiet Ride is “On” and your
unit is already preset to silence alerts when you travel below
25 MPH.
To change the speed at which alerts are silenced:
• Press and hold MENU button for 3 seconds to access the
Menu Function.
•Press release MENU button to scroll through functions
until you reach Quiet Ride. The display shows Quiet On
•Press and hold MUTE button for 3 seconds to access
speed options.
• Press and release MUTE button to scroll through speed
selections. With each press, speeds between 20 - 65 MPH
are displayed in increments of 5 MPH. (20, 25, 30, etc.)
Stop pressing button when you reach your desired Quiet
Ride speed. For example, if 45 is your desired setting, stop
pressing when the display shows 45 MPH .
The RL100 automatically saves your settings after 10 seconds,
exits the Menu Function and the display returns to the
main screen.
NOTE: Locations that you have “Marked for Alert” are not
affected by the Quiet Ride function and will initiate alerts at
any speed. (see page 12)

hold MARK button for 5 seconds at any time.
Mute Sounds
Using the MUTE button, the RL100 provides you two ways
to mute audio alerts (both voice and tones):
•OPTION 1: Silence all audio after an alert has sounded.
•OPTION 2: Silence all audio for a preset time before any
alert occurs. (Example: You may mute sounds
for 2 minutes prior to making a phone call.)

For either option, here’s how to mute your device:
After pressing the MUTE button, the display will show
Mute On_ and the voice will announce “Mute On.”
NOTE: While this feature is engaged you will only receive
new alerts as visual indications on the display.
Speed Monitor
The Speed Monitor function alerts the driver when a pre-
selected speed is exceeded. The Speed Monitor can be set to
any speed between 40-100 mph in 5 mph increments.
When the preset speed is exceeded:
•The RL100 emits a beeping alert tone accompanied by the
visual display blinking Slow then Down repeatedly.
•The alerts will continue until the vehicle’s speed is reduced
to below the Speed Monitor setting.
The factory default setting for Speed Monitor is “Off.” To
access and turn on this function:
•Press and hold FILTER button for 3 seconds.
•Press and release MUTE button to select the desired
maximum speed for alerts.
•5 seconds after your speed is selected, your setting will be
saved, the voice will announce “Exit” and your display
will return to the main screen. 13
