An example
Here is how you would turn the STi’s
AutoMute feature off.
1 Enter the Program Mode by holding both
the VOLUME/MUTE and SENS buttons
down for 2 seconds. The STi will beep
twice and display Program.
2 Then hold the RVW button down. The
STi will scroll through the categories,
starting with power-on indication
(Pilot), then alert lamp (Alamp), Voice,
Power-on sequence, signal strength meter,
and then AutoMute.
3 Release the RVW button when the STi
shows the AutoMute item. Since the
factory setting is for AutoMute to be on,
the STi will display aMute ON.
(If you accidentally don’t release the
Review button in time, and the STi goes to
the next category, hold the RVW button
down again, and scroll through the
categories again until aMute is displayed.)
4 Press the CHG button to change from
aMute ON to aMute OFF.
5 To complete the Programming, simply
wait 8 seconds without pressing any button.
The STi will display Complete, beep 4
times, and return to normal operation.
There are 8 user-selectable options so you
can customize your STi for your own
preferences.
The buttons labeled VOLUME/MUTE
and SENS are also used to enter the Program
Mode, REVIEW your current program
settings, and to CHANGE any settings as
desired. The abbreviations PGM, RVW, and
CHG are located on the lower part of the
display lens and are highlighted in graphics.
How to use Programming
1 To enter Program Mode, press and
hold both VOLUME/MUTE and SENS
buttons down for 2 seconds. (The unit
will beep twice, and will display the word
“Program”).
2 Then press the RVW button to review
the current settings. (You can either tap
the button to change from item to item, or
hold the button to scroll through the items).
3 Press the CHG button to change any
setting. (You can either tap the button to
change from setting to setting, or hold the
button to scroll through all the options).
4 To leave Program Mode, simply wait
8 seconds without pressing any button.
(The unit will display Complete, beep 4
times, and return to normal operation).
Factory Default Settings
To reset the STi to its original factory
settings, press and hold the
“VOLUME/MUTE,” and “SENS,” buttons
while turning the power on. The STi’s
display will provide a “Reset” message,
accompanied by an audible alert,
acknowledging the reset.
FCC Note: Modifications not expressly
approved by the manufacturer could
void the user’s FCC granted authority to
operate the equipment.

Radar Antenna and Laser Lens
The rear panel of your STi should have a
clear view of the road ahead. For best
performance, do not mount the STi
directly behind windshield wipers
or tinted areas. Page 6
Alphanumeric Display
The STi’s display will show Highway,
AutoScan, or City as its power-on indication.
If you prefer, you can choose other poweron indications. Pages 12-14
During an alert, the display will indicate
radar band, and a precise bar graph of signal
strength. Page 10
Note: In the Dark Mode the display will
not light during an alert. Page 9
Quick Reference Guide
To begin using your STi,
just follow these simple steps
1 Plug the small end of the power cord
into the side jack of the detector, and
plug the large end of the power cord
into your vehicle’s lighter socket.
2 Mount your STi on the windshield
using the supplied windshield mount.
3 Press the PWR button, located on the
left side of the front panel, to turn the
STi on.
4 Press and hold the VOLUME/MUTE
button to adjust the volume level.
Please read the manual to fully understand
STi’s operation and features.

Power Connection
To apply power to the STi, plug the small
end of the power cord, (telephone-type
connector) into the modular jack on the
STi’s right side, and plug the lighter plug
adapter into your vehicle's lighter socket or
accessory socket.
Your STi operates on 12 volts DC negative
ground only. The lighter plug provided is a
standard size and will work in most
vehicles. However, some vehicles may
require the optional European sleeve to
ensure a snug fit. If so, simply call our
service department to order one. This
sleeve slides over the Power cord’s lighter
plug adapter. Of course, your lighter socket
must be clean and properly connected for
proper operation.
Mounting Location
Where to mount STi
For optimum detection performance, we
recommend the following:
• Using the Windshield QuickMount, mount
your STi level, and high enough on your
front windshield to provide a clear view of
the road from the front and rear.
• Mount the STi away from windshield
wipers, other solid objects, and heavily
tinted areas that might obstruct the radar
antenna or laser lens.

Installation
Windshield QuickMount
The STi’s QuickMount windshield bracket is
designed for unobtrusive and hassle-free
mounting.
1 Depress the adjustment button on the
top of the STi (by the word BELTRONICS)
and slide the QuickMount bracket into the
slot until it is locked into the position which
best fits the angle of your windshield (there
are four settings available). For extremely
horizontal or extremely sloped windshields,
the QuickMount bracket can be bent.
To ensure that the suction cups
adhere to the windshield firmly,
be sure to keep both your
windshield and the suction cups clean.
2 To adjust the STi on your windshield,
use the QuickMount adjustment button
located on the top of the STi, and slide the
STi forward or backward to obtain a level
position.
When installed and adjusted properly, the
back top edge of the STi should rest solidly
against your windshield.
User’s Tip
You can leave the QuickMount bracket in
place on your windshield, and easily
remove STi by pressing the adjustment
button and sliding the STi off the mount.
Again, be sure to position the bracket
where it won’t present a hazard in the event
of an accident. Additional mounts are
available.

N0TE: Depending on your vehicle, the
lighter socket power may either be
continuously on, or it may be switched
on and off with your ignition switch.
CAUTION: A few vehicles (including some
Porsches) have windshields with a soft
anti-lacerative coating on the inside
surface. Use of suction cups will
permanently mar this coating. Consult
your dealership or the vehicle owner’s
manual to determine if your windshield
has this coating.
WARNING: BELTRONICS cannot
anticipate the many ways STi can be
mounted. It is important that you mount
STi where it will not impair your view
nor present a hazard in case of an
accident.
