How TotalShield
™
Technology Works
Beltronic’s TotalShield Technology keeps
RF signals from radiating from the detector.
Unlike other radar and laser detectors,
which merely move their RF signals (local
oscillators) to another frequency (which
will be detectable by future detector-
detectors), this revolutionary design keeps
you unseen by current radar detector-
detectors, including VG-2 and Spectre.
This unique design will also keep you
unseen from any future radar detector
detectors as well.
Although the BELTRONICS STi-R is a
completely undetectable radar, laser and
safety detector, driving techniques and
reactions to alerts can still draw unwanted
attention. Here are a few examples:
1. Hitting the brakes immediately when
the STi-R provides an alert can broadcast
use of a detector.
2. Traveling at night with a glow from a
radar detector’s display visible from
outside your vehicle can also draw
unwanted attention. The STi-R offers
adjustable brightness, including a full dark
mode which will provide audio alerts, but
no visual indication.
How Safety Radar Works
Safety Warning System, or SWS, uses a
modified K-band radar signal. The SWS
safety radar system has 64 possible
messages (60 currently allocated). The
SWS messages your STi-R can display are
listed on the facing page.
From the factory, your STi-R is
programmed with SWS decoding OFF. If
you wish to detect this system, use the
Programming feature to turn STi-R’s SWS
decoding ON.
NOTE: Some of the safety messages
have been condensed, so that each
message can be displayed on one or two
screens on STi-R’s eight-character display.
Since Safety radar technology is
relatively new, and the number of
transmitters in operation is not yet
widespread, you will not receive Safety
signals on a daily basis. Do not be
surprised if you encounter emergency
vehicles, road hazards and railroad
crossings that are unequipped with these
transmitters. If Safety transmitters become
more prevalent, these Safety radar signals
will become more common.
