Highway / AutoScan / City Switch
The “City” button selects the RX75’s sensi-
tivity. We recommend the “AutoScan”
mode for most driving.
The RX75’s exclusive AutoScan mode
provides long-range warning, with
minimum false alarms. In this mode, the
RX75’s internal computer continuously
analyzes all incoming signals and
intelligently adjusts the sensitivity –
eliminating the majority of false alarms.
You can also select conventional
“Highway” and “City” modes. When driving
in urban areas where annoying X-band
intrusion alarms and door openers are
common, City Mode can be engaged to
lower X-band sensitivity and reduce X-band
alerts. Full sensitivity is maintained on all
other bands. You can customize the RX75’s
City Mode sensitivity. See the Programming
section for details.
Display Brightness
The RX75’s display brightness is
automatically adjusted to suit ambient light
conditions in your vehicle. (The light sensor
is located inside the text display window)
If you prefer, you can program your
RX75 for a fixed brightness level (Maximum,
Medium, Minimum, or Dark). See the
Programming section for details.
Dark Mode
If you set the RX75 to its Dark Mode using
the Programming feature, the RX75 changes
to a very inconspicuous power-on
indication: a very dim “AD,” “HD,” or “CD.”
(In this display, the A, H, or C indicates
AutoScan, Highway, or City, and the D indi-
cates Dark.)
When the RX75 is in Dark Mode, the
display will not show visual alerts when it
detects signals. Only the audible alert will
tell you of detected signals. See the
Programming section for more details.
Audible Alerts
For Radar signals:
The RX75 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 occur faster 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 = chirping
K-band = buzzing
Ka-band = double-chirp
For Laser signals:
Since Laser signals are a possible threat
no matter how weak, the RX75 alerts you to
all laser signals with a full laser alert.

Controls and Features
Controls and Features
For Safety signals:
If you have turned on the SWS
detection in the RX75’s programming, it
will alert you to these signals with a double-
beep tone, and a corresponding text
message. A complete listing of the text
messages is on page 19.
If you haven’t programmed your RX75
to decode these safety signals (see pages 9,
13, 19), it will still detect them as K-band
radar signals.
Signal Strength Meter
The RX75’s matrix display consists of 280
individual LED’s, to provide an intuitive
ultra-bright display of signal strength and
text messages.
When the RX75 detects radar, it
displays the band of the radar signal (X, K,
or Ka), and a precise bar-graph of signal
strength.
Threat Display
™
The RX75’s exclusive Threat Display
™
option is an advanced display for
experienced detector users. Please use the
RX75 for a few weeks to get fully familiar
with its other features before using its
Threat Display
™
.
To use the Threat Display
™
instead of
the standard bar-graph signal strength
meter, you must select Threat Display
™
in
RX75’s Programming (see pages 9-13).
Threat Display
™
simultaneously tracks
multiple radar signals and provides the rela-
tive signal strength for each signal received.
Threat Display
™
can help you spot a
change in your normal driving environment;
for example, a traffic radar unit being
operated in an area where there are
normally other signals present.
The Threat Display
™
is actually a
miniature spectrum analyzer. It shows
the radar band, its relative signal strength.
KA9 K1 X5
Above is the Threat Display
™
if the
RX75 was detecting 1 strong Ka-band,
1 weak K-band, and medium X band
signal.
As you can see, there are numeric
values for signal strength after each band
designator. The higher the number, the
stronger the signal.
Note: If you use Threat Display
™
, the
brief signal shown in the power-on
sequence when you turn on your RX75 will
also be in Threat Display
™
: an “X” with
descending numeric value.
A few more examples will help you
better see how the Threat Display
™
works.
K9 X2
Here Threat Display
™
shows 1 strong
K-band signal, and a weak X-band signal.
