Beltronics RX75 Manual De Propietario

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.

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.

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.

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

Since Laser signals are a possible threat

no matter how weak, the RX75 alerts you to
all laser signals with a full laser alert.

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. 

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.

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.

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.
