Power Connector
The STi’s power jack uses a telephone-type
connector. This 4-conductor connector
only works with the included SmartPlug or
optional direct-wire, or our standard power
cord.

Signal Strength Meter
The STi’s alphanumeric display consists of
280 individual LEDs, to provide an intuitive
ultra-bright display of signal strength and
text messages.
The STi’s standard bar-graph signal
strength meter only displays information on
a single radar signal. If there are multiple
signals present, STi’s internal computer
determines which is the most important
threat to show on the bar-graph meter.
When STi detects radar, it displays the
band (X, K, Ka), and a precise bar-graph of
the signal strength. When the STi detects a
laser signal, the display will show “LASER.”
When it detects a POP signal, the display
will show “POP.”
Threat Display
Your STi’s Threat Display option is an
advanced display for experienced detector
users. Please use the STi for a few weeks to
get familiar with its other features before
using Threat Display.
To use the Threat Display instead of
the bar graph signal strength meter, you
must select Threat Display in the STi’s
Programming (see pages 12-15).
The STi’s Threat Display
simultaneously tracks multiple radar signals
and their relative signal strength.
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 what
band each signal is and its signal strength.
K a 9 K 2 X 1
Above is the Threat Display if the STi
was detecting a strong Ka-band, a weak
K-band, and a weak X-band signal.

A few more examples will help you
better see how the Threat Display works.
K 9 X 1
Here Threat Display shows a strong
K-band signal, and a weak X-band signal.
K a 1 X 9
Here Threat Display shows a weak
Ka-band signal, and a strong X-band
signal.
Threat Display Details
The band designators (X, K, Ka) will
stay on the display for a few seconds after
the signal has passed. This allows you to see
what the unit detected, even on very brief
signals.
Tech Display
The STi’s Tech Display option is for the
experienced detector user. In this mode,
the STi will display the actual numeric
frequency of the radar signal being
received.
K 2 4 . 1 5 0
Tech Display shows one K-band signal
at 24.150 gigahertz.
Even long-time detector users will
require a significant amount of time to get
familiar with this new level of information
about detected signals.
Audible Alerts
For Radar signals:
The STi 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.
X-band = chirping
K-band = buzzing
Ka-band = double-chirp
POP = full double-chirp
SWS = double buzz
For Laser signals:
Since laser signals are a possible threat
no matter how weak, the STi alerts you to
these bands at full signal strength.
For POP signals:
Since POP signals are a possible threat
no matter how weak, the STi alerts you to
these bands at full signal strength.
For Safety signals:
The STi 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 23.
NOTE:
If you are operating the STi in the
Dark mode, the display will not display
anything when a signal is detected. Only
the audio, and the flashing alert lamp on
the SmartPlug will be seen.
NOTE:
If you use Threat Display, the brief
signal shown in the power-on sequence
when you turn on your STi will also be
in Threat Display: an X with a decaying
numeric signal.
