Interpreting Alerts
Although the STi-R has a comprehensive
warning system and this handbook is as
complete as we can make it, only experience
will teach you what to expect from your
STi-R and how to interpret what it tells
you. The specific type of radar being used,
the type of transmission (continuous or
instant-on) and the location of the radar
source affect the radar alerts you receive.
The following examples will give you
an introduction to understanding the
STi-R’s warning system for radar, laser and
safety alerts.
Explanation
You are approaching a continuous radar
source aimed in your direction.
An instant-on radar source is being used
ahead of you and out of your view.
An instant-on radar source or laser source is
being used nearby. This kind of alert
requires immediate attention!
Laser is being used in the area. Because laser
is inherently difficult to detect, any laser
alert may indicate a source very close by.
A moving patrol car with continuous radar is
overtaking you from behind. Because these
signals are reflected (reflections are
increased by large objects), they may or may
not eventually melt into a solid point even
when the patrol car is directly behind you.
Alert
The STi-R begins to sound slowly, then the
rate of alert increases. The Signal Meter
ramps accordingly.
STi-R emits short alerts for a few seconds and
then falls silent only to briefly alert and fall
silent again.
STi-R suddenly sounds a continuous tone for
the appropriate band received. All segments
in the Signal Strength Meter are lit.
A brief laser alert.
STi-R receives weak signals. These signals
may be a little stronger as you pass large,
roadside objects. The signals increase in
frequency.
Explanation
You are approaching a radar unit concealed
by a hill or an obstructed curve.
A patrol car is traveling in front of you with a
radar source aimed forward. Because signals
are sometimes reflected off of large objects
and sometimes not, the alerts may seem
inconsistent.
A patrol car is approaching from the other
direction, sampling traffic with instant-on
radar. Such alerts should be taken seriously.
You are driving through an area populated
with radar motion sensors (door openers,
burglar alarms, etc.). Since these
transmitters are usually contained inside
buildings or aimed toward OR away from
you, they are typically not as strong or
lasting as a real radar encounter.
CAUTION: Since the characteristics of
these alerts may be similar to some of
the preceding examples, over
confidence in an unfamiliar area can
be dangerous. Likewise, if an alert in a
commonly traveled area is suddenly
stronger or on a different band than
usual, speed radar may be set up
nearby.
Alert
STi-R alerts slowly for a while and then
abruptly jumps to a strong alert.
STi-R alerts intermittently. Rate and strength of
alerts may be consistent or vary wildly.
STi-R alerts intermittently. Rate and strength of
signal increases with each alert.
STi-R gives an X-band or K-band alert
intermittently.
