Dark Mode
If you select Dark mode on the RX45, the 
display will not provide any indication that 
it is on.
 
NOTE: When the RX45 is in the
Dark Mode, the display will not show
visual alerts when it detects signals.
Only the audible alert will tell you of
detected signals.
Audible Alerts
For Radar signals:
 
The RX45 uses a Geiger-counter-like
sound to indicate the signal strength and 
type of radar signal being encountered.
 
When you encounter radar, a distinct
Audible Alert will sound and will increase 
as the signal gets stronger. This allows you 
to judge the distance from the signal source 
without taking your eyes from the road.
 
Each band has a distinct tone for easy
identification. 
 
X-band = chirp tone
K-band = buzz tone
Ku-band = chirp tone
Ka-band = double-chirp tone
For Laser signals:
 
Since Laser signals are a possible threat
no matter how weak, the RX45 alerts you 
to all laser signals with a full laser alert.
For Safety signals:
 
If you have turned on the SWS
detection in the RX45’s Preferences 
section, the RX45 will alert you to these 
signals with a audible double-chirp tone, 
and a corresponding text message. A 
complete listing of the text messages is on 
page 23.
 
If you haven’t turned on SWS in
Preferences, the RX45 will not decode 
these transmissions but will still detect 
them as K-band radar signal.
Signal Strength Meter
The RX45’s matrix display consists of 280 
individual LED’s, to provide an intuitive 
ultra-bright display of signal strength and 
text messages.
 
When it detects radar, it displays the
band of the radar (X, K, Ku or Ka), and a 
precise bar graph of signal strength.
Display Brightness
The RX45’s display brightness is 
automatically adjusted to suit ambient 
lighting conditions in your car. (The light 
sensor is located inside the display 
controller and may dim the display 
momentarily when accessing the buttons).
 
If you prefer, you can press the “BRT”
button located on the display controller to 
set your RX45 for a fixed brightness level 
(Auto, Minimum, Medium, Maximum or 
Dark).
