Power Button  
Mark Location Button (MRK)  
Press and hold to manually turn the STiR  
Plus on or off. If installed properly, the  
system will turn on or off automatically  
with the ignition.  
The “MRK” button allows you to mark a  
specific location and label it for future  
reference. Once marked, the STiR Plus will  
provide an alert before you reach this area  
again. This can be extremely useful when  
there are known speed traps or safety  
cameras in a particular location. Page 8  
Control Module  
Display Module  
Sensitivity Button (SENS)  
The “SENS” button selects the STiR Plus’s  
sensitivity. The choices are Highway (full  
sensitivity), AutoScan (based on the speed  
of the vehicle), City (reduced X and K-  
band sensitivity) and City No X, (same as  
City but without X-band). In general, we  
recommend AutoScan. Page 7  
Display Brightness (BRT)  
The “BRT” button selects your preferred  
brightness level. The factory default  
setting is Auto (automatic), which will  
adjust the display brightness based on the  
ambient light in the vehicle. See the  
Settings section for details.  
Volume Button (VOL)  
Press and hold the VOL button on the  
controller to adjust the alert volume level.  
The audio will ramp up to increase, down  
to decrease, accompanied by a bar-graph  
on the display.  
To change the direction of the audio  
ramping (down instead of up or vice  
versa) simply release the VOL button  
quickly press and hold it again to change  
its direction.  
Mute Button (Mute)  
Briefly press this button to silence the  
audio for a specific alert. (The audio will  
alert you to the next encounter.) Pages 6-7  
MatrixDisplay  
The STiR Plus’s alphanumeric display  
consists of 280 individual LEDs, to provide  
an intuitive ultra-bright display of  
signal strength and text messages. The  
STiR Plus’s display will show Highway,  
Autoscan, City or CityNoX as its power-on  
indication. If you prefer, you can choose  
other power-on indications. Pages 12-15  
During an alert, the display will

When optional Laser Blockers are  
connected:  
Sensitivity Button (SENS)  
The STiR Plus is typically wired to a  
switched supply at the vehicle’s fuse box.  
This allows the detector to turn on/off  
with the ignition. If you prefer, the power  
button can be used to manually turn the  
STiR Plus on or off.  
The MUTE button, located in the center of  
the STiR Plus’s controller, has several  
functions:  
1. Mute the audio during a single alert.  
To do this, briefly press the MUTE button  
during the alert. After that radar  
encounter has passed, the Mute will  
disengage, and the audio will return to  
your preset level.  
2. Lockout false alarms using TrueLock.  
To do this, simply press the Mute button  
(3) three consecutive times during the  
false alert. The first time the audio will  
mute as stated above. The second time the  
mute button is pressed; the display will  
read “Lockout?” To confirm and lockout  
that signal, press the mute button a third  
time.  
The “SENS” button selects the STi-R’s  
sensitivity mode. We recommend  
AutoScan mode for most driving.  
4. Disengage “Laser Blockers. To do this,  
simply double-tap the mute button during  
a laser alert once you’ve adjusted your  
speed. This will put the Laser Shifters into  
a “receive only” mode for approximately  
(1) one minute. Once this time has passed,  
the Shifters will automatically return to  
the “shifting” mode.  
NOTE: Blockers must be turned on  
in Settings. See Settings section for  
details.  
5. Once the vehicle is under 25 mph,  
press and hold to disable the Shifters for  
an extended period of time. Once the  
vehicle reaches 25 mph, the Shifters will  
reset and return to Shift mode.  
Highway (Highway Mode)  
In this setting, the STi-R will detect all  
signals at maximum range.  
Power-On Indication  
Once your STiR Plus’s is installed, the  
system will turn on with the ignition.  
Once the start-up sequence is complete,  
the display will show “Highway,  
“AutoScn”, “City” or “City NoX” to indicate  
which sensitivity mode it is in.  
If you prefer, you can select alternate  
power-on displays. See the Settings  
section for details.  
AutoScn (AutoScan Mode)  
In this setting the STi-R’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 STD (City Mode)  
Volume Control  
NOTE: Visually scan the area to  
ensure no real threat exists before  
locking out any signals.  
Once a signal has been locked out, the  
satellite icon on the display will rotate,  
giving you a visual indication that it is  
detecting that signal, but no alert will be  
given.  
3. Unlock a signal. To do this, simply  
press (do not hold) the Mute button while  
the icon is rotating. An “Unlock” message  
will be displayed. Press the mute button  
again to confirm and unlock that signal.  
AutoMute  
In this setting, X and K-band sensitivity is  
further reduced to eliminate unwanted  
false alarms in congested urban areas.  
Press and hold the VOL button on the  
controller to adjust the alert volume level.  
The audio will ramp up and down,  
accompanied by a bar-graph on the display.  
Once your desired level is reached, simply  
release the button. This audio level will be  
stored in memory, even after the detector  
is turned off.  
NOTE: To change the direction of  
the audio ramping (e.g. down instead  
of up) simply release the VOL button  
quickly and press and hold again.  
Your STiR Plus has our patented AutoMute  
feature. After the STiR Plus 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.  
City NoX (City Mode with NoX)  
In this setting, K-band sensitivity is the  
same as City STD, however, X-band is  
completely turned off.  
If you prefer, you can turn AutoMute  
off. See the Settings section for details.  
WARNING: Do not use the STi-R City  
NoX mode unless you are  
absolutely certain that there are no  
traffic radar guns using X-band in  
your area.

Controls and Features  
Safety Camera  
Mark Locations  
The first time you press the Mute  
button, the audio will mute. The second  
time the display will show “Lockout?”  
accompanied by a voice prompt asking if  
you want to lockout this signal. The third  
time you press the Mute button, the  
location and frequency of that signal is  
stored in memory. The display will show  
“Stored” to acknowledge the information  
has been captured.  
The warning distance for each label is:  
Speed Trap =  
.3 miles, or approximately 1,584 feet.  
Speed Camera =  
500’ when traveling below 55mph,  
or 1000’ above 55mph  
Average Speed Cameras =  
500’ when traveling below 55mph,  
or 1000’ above 55mph  
Your STiR Plus comes pre-loaded with  
safety camera locations in its memory. To  
turn these on or off, see the “Markers”  
section in Settings.  
The Mark Location feature allows you to  
mark any location for future reference.  
Once marked, the STiR Plus will provide  
an alert, accompanied by the label you  
assigned to it, on the display.  
There are (4) different labels you can  
use when marking a location: Speed Trap  
(“SPDTRAP”), Speed Camera  
(“SPEEDCAM”), red light camera  
(“REDLIGHT”) and other (“OTHER”).  
To mark a location, simply press the  
“MRK” button. The display will show  
“MARK?, accompanied by a voice message.  
Press the “MRK” button again, and the  
labels appear, starting with “SPDTRAP. If  
this is not the label you want to use,  
simply press the “MUTE” button to scroll  
through the other options. Once you  
reached the label you want, simply press  
the “MRK” button once more to confirm.  
The word “MARKED” will appear on the  
display, accompanied by a voice prompt  
confirming you have marked and labeled  
this location.  
AutoLock/Auto UnLock  
(X and K-bands only)  
AutoLock constantly analyzes all incoming  
signals as you drive. If the same signal is  
detected at the same location  
approximately (3) three times, the STiR  
Plus will automatically lock it out as a false  
alarm. Once this signal has been locked  
out, no alert will be given at this location  
unless it’s a new or different signal.  
Once a signal has been locked out and  
stored in memory, the STiR Plus will also  
automatically unlock a signal if it is not  
present the next time you pass that  
location. This reduces the chances of  
locking out a real threat.  
Red Light Camera =  
250 feet  
Other =  
Audible Alerts  
For Radar signals:  
500’ when traveling below 55mph,  
or 1000’ above 55mph  
The STiR Plus 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.  
NOTE:  
GPS must be on in Settings.  
Locking Out False Alarms  
X-band = beep  
K-band = brap  
Ka-band = double-brap  
POP = full double-chirp  
Laser = rapid fire beeping  
SWS = double buzz  
To lock out a known false alarm, (X and K-  
band radar, and Laser) simply press the  
Mute button on the controller (3) three  
times during the false alert.  
NOTE: It is important to visually  
look around to make certain no  
traffic radar is present before locking  
out a signal.  
Once marked, the STiR Plus will  
provide an alert before you reach this area  
the next time.  
NOTE: You must drive out of the  
marked area before the mark location  
alert will work.  
At low speeds, (below 20 mph) radar alerts  
will be reduced to a double-tone based on  
the band received (e.g. double brap for k-  
band).

Controls and Features  
For Laser signals:  
Display Brightness  
ThreatDisplay  
better see how the Threat Display works.  
Since laser signals are a possible  
threat no matter how weak, the STiR Plus  
alerts you to these bands at full signal  
strength.  
The STiR Plus’s display brightness is  
automatically adjusted by a sensor located  
behind the display lens. (factory default)  
If you prefer, you can select one of the  
following fixed levels of brightness  
including Minimum, Medium, Maximum  
or Full Dark by pressing the “BRT” button  
located on the controller.  
Your STiR Plus’s ThreatDisplay option is an  
advanced display for experienced detector  
users. Please use the STiR Plus for a few  
weeks to get familiar with its other  
features before using this meter type.  
To use the ThreatDisplay instead of  
the standard bar-graph signal strength  
meter, you must select ThreatDisplay in  
the STiR Plus’s Settings (see pages 12-15).  
The STiR Plus’s ThreatDisplay Display  
simultaneously tracks multiple radar  
signals and their relative signal strength.  
This 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.  
K9 X1  
Here Threat Display shows a strong  
K-band signal, and a weak X-band signal.  
For POP signals:  
Ka1 X9  
Since POP signals are extremely fast K  
or Ka bursts, and a possible threat no  
matter how weak, the STiR Plus alerts you  
to these bands at full signal strength.  
Here Threat Display shows a weak  
Ka-band signal, and a strong X-band  
signal  
Signal Strength Meter  
The STiR Plus’s standard bar-graph meter  
only displays information on a single radar  
signal. If there are multiple signals present,  
the STiR Plus’s internal computer  
determines which is the most important  
threat to show on the bar-graph meter.  
When the STiR Plus detects radar, it  
displays the band (X, K, Ka), and a precise  
bar-graph of the signal strength. When the  
STiR Plus detects a laser signal, the display  
will show “LASER.” When it detects a POP  
signal, the display will show “POP.”  
Tech Display  
For Safety signals:  
The STiR Plus’s Tech Display option is for  
the experienced detector user. In this  
mode, the STiR Plus will display the actual  
numeric  
frequency of the radar signal being  
received.  
The STiR Plus 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 25.  
The ThreatDisplay Display is actually  
a miniature spectrum analyzer. It shows  
what band each signal is and its signal  
strength.  
Marked Locations  
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.  
The STiR Plus will alert you to marked  
locations with a double-beep tone, and a  
corresponding text message. A complete  
list of mark location labels are on page 8.  
Ka9 K2 X1  
NOTE: If you are operating the  
STiR Plus in the Dark mode, the  
display will not display anything  
when a signal is detected. However,  
the back light on the Mute button,  
located on the controller, will flash to  
give you a visual alert.  
Above is the Threat Display if the  
STi-R was detecting a strong Ka-band, a  
weak K-band, and a weak X-band signal.  
Voice Alerts  
The STiR Plus provides digital voice  
announcements (factory default) for alerts,  
feedback for button selections, and  
Settings.  
If you prefer, you can turn off the  
voice feature in Settings. See the Settings  
section for details.

Interpreting Alerts  
Alert  
Explanation  
Although the STiR Plus has a  
transmission (continuous or instant-on)  
and the location of the radar source affects  
the radar alerts you receive.  
The following examples will give you  
an introduction to understanding the STiR  
Plus’s warning system for radar, laser and  
safety alerts.  
comprehensive warning system and this  
Manual is as complete as we can make it,  
only experience will teach you what to  
expect from your STiR Plus and how to  
interpret what it tells you. The specific  
type of radar being used, the type of  
The STiR Plus alerts intermittently. Rate and  
strength of alerts may be consistent or vary  
wildly.  
A patrol car is travelling 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.  
The STiR Plus 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.  
Alert  
Explanation  
The STiR Plus begins to sound slowly, then  
the rate of alert increases until the alert  
becomes a solid tone. The Signal Meter  
ramps accordingly.  
You are approaching a continuous radar  
source aimed in your direction.  
The STiR Plus gives an X-band alert  
intermittently.  
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.  
The STiR Plus 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.  
The STiR Plus 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!  
CAUTION: Since the characteris-  
tics 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.  
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.  
The STiR Plus 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.  
The STiR Plus alerts slowly for awhile and  
then abruptly jumps to a strong alert.  
You are approaching a radar unit concealed  
by a hill or an obstructed curve.

How Radar Works  
Traffic radar, which consists of  
microwaves, travels in straight  
Because intrusion alarms and motion  
sensors often operate on the same  
extreme false alerts in your area. If not,  
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.  
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.  
frequency as X, and K-band radar, your  
STiR Plus will occasionally receive non-  
police radar signals. Since these X-Band  
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 STiR Plus’s radar detection  
abilities are fully operational.  
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.  
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).  
NOTE: According to the operator’s  
manual from the radar gun  
manufacturer, tickets should not be  
issued in POP mode.  
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.  
How TSR Works  
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 countries, generate  
K-band signals to measure the flow of  
traffic on a given road. Unfortunately most  
detectors see this as a real threat and will  
alert you to it unnecessarily. 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 set up as an  
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.  
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.

Beltronics’s TotalShield Technology keeps  
RF signals from radiating from the  
detector. Unlike

detectors, which  
TrueLock uses exact position and the  
actual frequency of a signal to eliminate it  
as a false alarm. Once a signal is locked out,  
a box is created (approximately a 1⁄2 mile  
radius) around that location to lock it out  
from all directions.  
NOTE: Thoroughly look around  
and make sure that no real radar is  
being used to monitor your speed  
before you manually lock out a signal.  
Automatic door openers use more  
than one source, so TrueLock will  
automatically lock out other X and K-band  
sources in close proximity of the first to  
captures these.  
AutoLock uses TrueLock to lock out false  
alerts, however signals are locked out  
automatically over time vs. manually using  
the Mute button.  
As you drive, STiR Plus records  
location and frequency for each signal  
detected. If that same signal (by  
frequency) is in the same location  
approximately three (3) times, AutoLock  
will automatically lock it out as a false  
alarm. A “stored” message will be  
displayed, accompanied by a low-level  
alert.  
twenty four orbiting satellites and was  
developed by the U.S. military. There are  
at least four satellites visible at any given  
time every day.  
A GPS receiver is designed to locate  
and receive data from four of these  
satellites. This data includes the distance  
to your location from each of the satellites.  
Once the distance from each satellite is  
known, the receiver can calculate and  
pinpoint your exact location.  
merely move their  
RF signals (local oscillators) to another  
frequency (which will be detectable by  
future detector-detectors), this  
revolutionary design keeps you unseen by  
current radar detector-detectors,  
including VG-2 and Spectre. This unique  
design will also keep you unseen from any  
future radar detector detectors as well.  
Although the STiR Plus 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 STiR Plus provides an alert can  
broadcast use of a detector.  
How Auto UnLock Works  
If you accidentally lock out a real  
threat, (visually see the officer) simply  
press and hold the Mute button to unlock  
it from STiR Plus’s memory.  
Auto UnLock automatically unlocks stored  
TrueLock signals if they are not present in  
the same location. This is particularly  
useful if you accidently lock out a true  
threat, or if an officer is parked in a  
shopping mall with automatic door  
openers.  
2. Traveling at night with a glow from a  
radar detector’s display visible from  
outside your vehicle can also draw  
unwanted attention. The STiR Plus offers  
adjustable brightness, including a full dark  
mode which will provide audio alerts, but  
no visual indication.
