Highway / AutoScan / City Switch
The “City” button selects the RX75 PLUS’s
sensitivity. We recommend the “AutoScan”
mode for most driving.
The RX75 PLUS’s exclusive AutoScan
mode provides long-range warning, with
minimum false alarms. In this mode, the
RX75 PLUS’s internal computer continu-
ously 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
PLUS’s City Mode sensitivity. See the
Programming section for details.
Display Brightness
The RX75 PLUS’s display brightness is auto-
matically 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 PLUS for a fixed brightness level
(Maximum, Medium, Minimum, or Dark).
See the Programming section for details.
Dark Mode
If you set the RX75 PLUS to its Dark Mode
using the Programming feature, the RX75
PLUS 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 indicates Dark.)
When the RX75 PLUS 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 PLUS 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 PLUS alerts
you to all laser signals with a full laser alert.

Controls and Features
For Safety signals:
If you have turned on the SWS detec-
tion in the RX75 PLUS’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
PLUS 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 PLUS’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 PLUS 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 PLUS’s exclusive Threat Display
™
option is an advanced display for experi-
enced detector users. Please use the RX75
PLUS 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 PLUS’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, and its relative signal strength.
KA9 K1 X5
Above is the Threat Display
™
if the
RX75 PLUS was detecting 1 strong Ka-
band, 1 weak K-band, and a 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
PLUS 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.
