Controls and Features
Power
To turn STi on or off, press the PWR button
located on the front left side. When you
turn STi on, it goes through a sequence of
alerts.
If you prefer, you may program your
STi for a shorter power-on sequence. See
the Programming section for details.
Volume
Press and hold the VOLUME/MUTE button,
located in the center of the front panel, to
adjust the STi’s alert volume level. The
audio will ramp up and down, accompanied
by a bar-graph on the display. Once you’ve
reached your preferred audio level, simply
release the button.
Power-on indication
After STi’s start-up sequence is complete,
the alphanumeric display will show
Highway, AutoScan, City or City NoX to
indicate which sensitivity mode is selected.
If you prefer, you can select alternate
power-on displays. See the Programming
section for details.
Voice Alerts
The STi provides digital voice
announcements (factory default) for alerts.
If you prefer, you can turn off the voice
announcement feature and have the STi
provide audible tones without the voice
announcement. See programming section
for details.
AutoMute
Your STi has our patented AutoMute
feature. After STi alerts you to a radar
encounter at the volume you have selected,
the AutoMute feature will automatically
reduce the volume to a lower level. This
keeps you informed without the annoyance
of a continuous full-volume alert.
If you prefer, you can turn the
AutoMute feature off. See the Programming
section for details.
Mute
The VOLUME/MUTE button, located in the
center of the STi’s front panel, allows you to
silence the audio alert during a radar
encounter.
To mute the audio for a single specific
signal, briefly press the VOLUME/MUTE
button. After that radar encounter has
passed, the mute will automatically reset
and the audio will alert you to the next
encounter.

Sensitivity Button (SENS)
The “SENS” button selects the STi’s
sensitivity mode. We recommend AutoScan
mode for most driving.
Highway Mode (Highway)
In this setting, the STi will detect all signals
at maximum range.
AutoScan Mode (AutoScan)
In this setting the STi's internal computer
continuously analyzes all incoming signals
and intelligently filters out unwanted X and
K-band false alarms from automatic door
openers and motion sensors. Full
sensitivity is maintained on all other bands
City (City STD)
In this setting, X and K-band sensitivity is
further reduced to eliminate unwanted false
alarms in congested urban areas.
City No X (City NoX)
In this setting, K-band sensitivity is the same
as City STD, however, X-band is completely
turned off.
9
Brightness
The STi’s brightness is controlled by a
photocell located behind the front display
lens. This photocell will automatically adjust
the display and backlit buttons based on the
ambient light in your vehicle. If you prefer,
you can select a fixed brightness level,
including Full Dark Mode. See the
programming section for details.
WARNING:
Do not use the STi in this
mode unless you are absolutely certain
that there are no traffic radar guns using
X-band in your area.
