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

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.

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.

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.

an introduction to understanding the STiR
Plus’s warning system for radar, laser and
safety alerts.

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 Laser Works
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.

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.

at least four satellites visible at any given
time every day.
A GPS receiver is designed to locate

Once the distance from each satellite is
known, the receiver can calculate and

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.
