Mounting Location
WARNING: BELTRONICS cannot
anticipate the many ways STi MAGNUM
can be mounted. It is important that you
mount STi MAGNUM where it will not
impair your view nor present a hazard
in case of an accident.
Where to mount STi MAGNUM
For optimum detection performance, we
recommend the following:
• Using the Windshield QuickMount,
mount your STi MAGNUM level, and
high enough on your front windshield to
provide a clear view of the road from the
front and rear.
• Mount the STi MAGNUM away from
windshield wipers, other solid objects, and
heavily tinted areas that might obstruct the
radar antenna or laser lens.
Windshield QuickMount
The STi MAGNUM’s QuickMount windshield bracket is designed for unobtrusive
and hassle-free mounting and removal.
1 Depress the adjustment button on
the top of the STi MAGNUM (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 MAGNUM on your
windshield, use the QuickMount
adjustment button located on the top
of the STi MAGNUM, and slide the STi
MAGNUM forward or backward to obtain a
level position.
NOTE: When installed and adjusted
properly, the back top edge of the STi
MAGNUM should rest solidly against
your windshield.
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.
User’s Tip
You can leave the QuickMount bracket
in place on your windshield, and easily
remove STi MAGNUM by pressing the
adjustment button and sliding the STi
MAGNUM 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 for other
vehicles in your household.
Controls and Features
Power Button (PWR)
Voice Alerts
To turn STi MAGNUM on or off, press the
PWR button located on the front left side.
When you turn STi MAGNUM on, it goes
through a sequence of alerts.
If you prefer, you may program your
STi MAGNUM for a shorter power-on
sequence. See the Programming section for
details.
The STi MAGNUM provides digital voice
announcements (factory default) for alerts.
If you prefer, you can turn off the voice
announcement feature and have the STi
MAGNUM provide audible tones without
the voice announcement. See programming
section for details.
Volume
Your STi MAGNUM has our patented
AutoMute feature.After STi MAGNUM 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.
Press and hold the VOLUME•MUTE
button, (or Mute button on the SmartPlug)
located in the center of the front panel,
to adjust the STi MAGNUM’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.
To change the direction of the audio
ramping (down instead of up or vice versa)
simply release the VOLUME•MUTE button
quickly press and hold it again to change its
direction.
Power-on indication
After STi MAGNUM’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.
AutoMute
Mute
The VOLUME/MUTE button, located in the
center of the STi MAGNUM’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 MAGNUM’s
sensitivity mode.We recommend AutoScan
mode for most driving.
Highway Mode (Highway)
In this setting, the STi MAGNUM will detect
all signals at maximum range.
AutoScan Mode (AutoScan)
In this setting the STi MAGNUM’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 NoX (City NoX)
In this setting, K-band sensitivity is the
same as City STD, however, X-band is
completely turned off.
WARNING: Do not use the STi MAGNUM
City NoX mode unless you are
absolutely certain that there are no
traffic radar guns using X-band in your
area.
Brightness
The STi MAGNUM’s brightness is controlled
by a sensor located behind the front display
lens.This sensor 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.
Sensor location
SmartPlug
SmartPlug is a special power
cord that has a power-on
indicator, a bright alert light
that warns of radar or laser, and
a convenient mute button right on the plug.
It’s the perfect addition for any vehicle
where reaching the detector mute button
on the windshield is a stretch.And for
discreet night driving, put STi MAGNUM in
the Dark Mode, and use the SmartPlug for
your visual alerts. Other cars won’t know
you have a detector.
Controls and Features
Audible Alerts
For Radar signals:
The STi MAGNUM 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 MAGNUM
alerts you to these bands at full signal
strength.
For POP signals:
Since POP signals are extremely fast
K or Ka bursts, and a possible threat no
matter how weak, the STi MAGNUM alerts
you to these bands at full signal strength.
For Safety signals:
The STi MAGNUM 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.
Power Connector
The STi MAGNUM’s power jack uses a
telephone-type connector.This 4-conductor
connector only works with the included
coiled SmartPlug or direct-wire cord.
Signal Strength Meter
The STi MAGNUM’s alphanumeric display
consists of 280 individual LEDs, to provide
an intuitive ultra-bright display of signal
strength and text messages.
The STi MAGNUM’s standard bar-graph
signal strength meter only displays
information on a single radar signal. If there
are multiple signals present, STi MAGNUM’s
internal computer determines which is the
most important threat to show on the bargraph meter.
When STi detects radar, it displays the
band (X, K, Ka), and a precise bar-graph of
the signal strength.When the STi MAGNUM
detects a laser signal, the display will show
“LASER.”When it detects a POP signal, the
display will show “POP.”
NOTE: If you are operating the STi
MAGNUM 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.
Threat Display
Your STi MAGNUM’s Threat Display option
is an advanced display for experienced
detector users. Please use the STi MAGNUM
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
MAGNUM’s Programming (see pages 12-15).
The STi MAGNUM’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.
Ka9K2X1
Above is the Threat Display if the
STi MAGNUM was detecting a strong
Ka-band, a weak K-band, and a weak Xband signal.
A few more examples will help you
better see how the Threat Display works.
K9 X1
Here Threat Display shows a strong
K-band signal, and a weak X-band signal.
Ka1 X9
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 MAGNUM’s Tech Display option
is for the experienced detector user. In
this mode, the STi MAGNUM will display
the actual numeric frequency of the radar
signal being received.
K 24.150
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.

Technical Details
Interpreting Alerts
Alert
Explanation
STi MAGNUM alerts slowly for a while and
then abruptly jumps to a strong alert.
You are approaching a radar unit concealed
by a hill or an obstructed curve.
STi MAGNUM alerts intermittently. Rate and
strength of alerts may be consistent or vary
wildly.
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.
You are approaching a continuous radar
source aimed in your direction.
STi MAGNUM alerts intermittently. Rate and
strength of signal increases with each alert.
A patrol car is approaching from the other
direction, sampling traffic with instant-on
radar. Such alerts should be taken seriously.
STi MAGNUM emits short alerts for a few
seconds and then falls silent only to briefly
alert and fall silent again.
An instant-on radar source is being used
ahead of you and out of your view.
STi MAGNUM gives an X-band or K-band alert
intermittently.
STi MAGNUM suddenly sounds a continuous
tone for the appropriate band received.All
segments in the Signal Strength Meter are lit.
An instant-on radar source or laser source is
being used nearby.This kind of alert requires
immediate attention!
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.
A brief laser alert.
Laser is being used in the area. Because laser
is inherently difficult to detect, any laser alert
may indicate a source very close by.
STi MAGNUM receives weak signals.These
signals may be a little stronger as you pass
large, roadside objects.The signals increase in
frequency.
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.
Although the STi MAGNUM 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 MAGNUM 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
MAGNUM’s warning system for radar, laser
and safety alerts.
Alert
Explanation
The STi MAGNUM begins to sound slowly,
then the rate of alert increases.The Signal
Meter ramps accordingly.
CAUTION: Since the characteristics of
these alerts may be similar to some of
the preceding examples,
overconfidence 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.
Technical Details
How Radar Works
Traffic radar, which consists of microwaves,
travels in straight lines and is easily
reflected by objects such as cars, trucks,
even guardrails and overpasses. Radar
works by directing its microwave beam
down the road.As your vehicle travels into
range, the microwave beam bounces off
your car, and the radar antenna looks for
the reflections. Using the Doppler Principle,
the radar equipment then calculates your
speed by comparing the frequency of
the reflection of your car to the original
frequency of the beam sent out.
Traffic radar has limitations, the most
significant of these being that it typically
can monitor only one target at a time. If
there is more than one vehicle within
range, it is up to the radar operator to
decide which target is producing the
strongest reflection. Since the strength of
the reflection is affected by both the size
of the vehicle and its proximity to the
antenna, it is difficult for the radar operator
to determine if the signal is from a sports
car nearby or a semi-truck several hundred
feet away.
Radar range also depends on the
power of the radar equipment itself.
The strength of the radar unit’s beam
diminishes with distance.The farther the
radar has to travel, the less energy it has for
speed detection.
Because intrusion alarms and motion
sensors often operate on the same
frequency as X-Band or K-band radar, your
STi MAGNUM will occasionally receive
non-police radar signals. Since these
transmitters are usually contained inside
of a building, or aimed toward the ground,
they will generally produce much weaker
readings than will a true radar encounter.
As you become familiar with the sources of
these pseudo alarms in your daily driving,
they will serve as confirmation that your
STi MAGNUM’s radar detection abilities are
fully operational.
How “POP” Works
“POP” mode is a relatively new feature for
radar gun manufacturers. It works by
transmitting an extremely short burst,
within the allocated band, to identify
speeding vehicles in traffic. Once the target
is identified, or “POPPED,” the gun is then
turned to its normal operating mode to
provide a vehicle tracking history, (required
by law).
Traffic Signal Rejection Software
Your radar detector includes a new
optional boost in anti-falsing software to
eliminate excessive alerts from erroneous X
and K-band sources. One example of this is
traffic flow monitoring systems.These
systems, which are becoming more widely
used in several states, generate K-band
signals to measure the flow of traffic on
interstate highways. Unfortunately most
detectors alert to these sources as
a real threat. Our new proprietary
software (TSR), intelligently sorts,
ranks and rejects this type of false alarm
automatically.The result is ultimate
protection without excessive false alarms.
The TSR software is turned on by
default in the Programming section of your
detector. If you believe this type of system
isn’t used in your area, you can simply turn
it off. Otherwise, your detector is ready to
start protecting you right out of the box.
If you have any questions about this
new feature, please give us a call or visit our
website for more details.
How Laser (Lidar) Works
Laser speed detection is actually LIDAR
(Light Detection and Ranging). LIDAR
guns project a beam of invisible infrared
light.The signal is a series of very short
infrared light energy pulses, which move,
in a straight line, reflecting off your car and
returning to the gun. LIDAR uses these light
pulses to measure the distance to a vehicle.
Speed is then calculated by measuring how
quickly these pulses are reflected given the
known speed of light.
LIDAR (or laser) is a newer technology
and is not as widespread as conventional
radar, therefore, you may not encounter
laser on a daily basis.And unlike radar
detection, laser detection is not prone
to false alarms. Because LIDAR transmits
a much narrower beam than does radar,
it is much more accurate in its ability to
distinguish between targets and is also
more difficult to detect. AS A RESULT,
EVEN THE BRIEFEST LASER ALERT
SHOULD BE TAKEN SERIOUSLY.
There are limitations to LIDAR
equipment. LIDAR is much more sensitive
to weather conditions than RADAR, and a
LIDAR gun’s range will be decreased by
anything affecting visibility such as rain,
fog, or smoke.A LIDAR gun cannot operate
through glass and it must be stationary in
order to get an accurate reading. Because
LIDAR must have a clear line of sight and
is subject to cosine error (an inaccuracy,
which increases as the angle between the
gun and the vehicle, increases) police
typically use LIDAR equipment parallel to
the road or from an overpass. LIDAR can be
used day or night.
Technical Details
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 detectordetectors), this revolutionary design keeps
you unseen by current radar detectordetectors, 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 MAGNUM
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 MAGNUM provides an alert can
broadcast use of a detector.
2. Visible power cords, brackets and
suction cup marks on the glass can also
advertise to others that you have a detector.
3. Traveling at night with a glow from a
radar detector’s display visible from outside
your vehicle can also draw unwanted
attention.The STi MAGNUM offers
adjustable brightness, including a full dark
mode which will provide audio alerts, but
no visual indication except for the alert
LED on the SmartPlug.
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 MAGNUM can display
are listed on the facing page.
From the factory, your STi MAGNUM
is programmed with SWS decoding OFF.
If you wish to detect this system, use
the Programming feature to turn STi
MAGNUM’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 MAGNUM’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
not equipped with these transmitters. If
Safety transmitters become more prevalent,
these Safety radar signals will become more
common.
