Mounting Location
WARNING: BELTRONICS cannot anticipate
the many ways the V928i can be mounted.
It is important that you mount your V928i
where it will not impair your view nor
present a hazard in case of an accident.
Where to mount your V928i
For optimum detection performance, we
recommend the following:
• Using the QuickMount bracket, mount
your V928i level, and high enough on your
front windshield to provide a clear view of
the road from the front and rear.
• Mount the V928i away from windshield
wipers, other solid objects, and heavily
tinted areas that might obstruct the radar
antenna or laser lens.

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
the V928i by pressing the adjustment
button and sliding the V928i 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.
Windshield QuickMount
The V928i’s QuickMount bracket is
designed for unobtrusive and hassle-free
mounting.
1 Depress the QuickMount button
on the top of the V928i (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 V928i on your
windshield, use the QuickMount
adjustment button located on the top of
the V928i, and slide the V928i forward
or backward to obtain a level horizontal
position.
When installed and adjusted properly, the
back top edge of the V928i should rest
solidly against your windshield.

Controls and Features
Power
To turn your V928i on or off, press the PWR
button located on the top. When you turn
your V928i on, it goes through a sequence
of alerts.
If you prefer, you may program your
V928i for a shorter power-on sequence. See
the Programming section for details.
Volume
Press and hold the Volume/Mute button
located on the top case to adjust the
V928i’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 the V928i’s start-up sequence is
complete, the alphanumeric display will
show Highway or City 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 V928i provides digital voice
announcements of radar and laser bands
detected. If Safety Radar (SWS) is turned
on, a safety radar message will also be
announced. See the Programming section
for details.
If you prefer, you can turn Voice Alerts
off. See Programming section for details.
AutoMute
Your V928i has our patented AutoMute
feature. After the V928i 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 Mute button, located on the V928i’s
top case, allows you to silence the audio
alert during a radar encounter.
To mute the audio for a single specific
signal, briefly press the Mute button. After
that radar encounter has passed, the mute
will automatically reset and the audio will
alert you to the next encounter.
8
Highway / City Button
The City button selects the V928i’s
sensitivity mode. We recommend the
Highway mode for most driving.
When driving in urban areas where
annoying X-band intrusion alarms and door
openers are common, City mode can be
engaged to lower X-band sensitivity and
reduce X-band alerts. Full sensitivity is
maintained on all other bands. See the
Programming section for details.
Brightness
The V928i’s BRT button selects the
brightness of your V928i’s display. There are
four settings: Maximum, Medium, Minimum,
and Dark. Press the BRT button to select
your preferred brightness.
9
Dark Mode
When you select the Dark mode with the
BRT switch, your V928i changes to a very
inconspicuous power-on indication: a
very Dim HD or CD. (In this display, the H
or C indicates Highway or City, and the D
indicates Dark.)
When the V928i is in the Dark mode,
the display will not show visual alerts when
V928i detects signals. Only the audible alert
will tell you of detected signals.

Controls and Features
10
SmartCord™ Power Connector
The V928i’s power jack uses a telephone-
type connector. This 4-conductor
connector only works with the included
SmartCord or optional direct-wire.
For more information or to order, call
us toll-free at 1-800-341-2288.
Signal Strength Meter
Your V928i’s alphanumeric display consists
of 280 individual LEDs, to provide an
intuitive ultra-bright display of signal
strength and text messages.
The V928i’s standard bar-graph signal
strength meter only displays information
on a single radar signal. If there are multiple
signals present, the V928i’s internal
computer determines which is the most
important threat to show on the bar-graph
meter.
When your V928i detects radar, it
displays the band (X, K, or Ka), and a
precise bar-graph of the signal strength.
When your V928i detects a laser signal, the
display will show LASER.
NOTE: If you are operating the V928i
in the Dark mode, the display will not light
when a signal is detected, only the audio
will be heard.
11
Audible Alerts
For Radar signals:
Your V928i 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.
Each band has a distinct tone for easy
identification.
X-band = chirping
K-band = buzzing
Ka-band = double-chirp
POP = full double-chirp
For Laser and POP signals:
Since laser and POP signals (if turned
on) are a possible threat no matter how
weak, the V928i alerts you to these bands at
full strength.
For Safety signals:
Your V928i 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 21.

Interpreting Alerts
Although the V928i 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 V928i 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 your
V928i’s warning system for radar, laser and
safety alerts.
Explanation
You are approaching a continuous radar
source aimed in your direction.
An instant-on radar source is being used
ahead of you and out of your view.
An instant-on radar source or laser source is
being used nearby. This kind of alert requires
immediate attention!
Laser is being used in the area. Because laser
is inherently difficult to detect, any laser alert
may indicate a source very close by.
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.
Alert
The V928i begins to sound slowly, then the
rate of alert increases. The Signal Meter ramps
accordingly.
The V928i emits short alerts for a few seconds
and then falls silent only to briefly alert and
fall silent again.
The V928i suddenly sounds a continuous
tone for the appropriate band received. All
segments in the Signal Strength Meter are lit.
A brief laser alert.
The V928i receives weak signals. These
signals may be a little stronger as you pass
large, roadside objects. The signals increase in
frequency.
Explanation
You are approaching a radar unit concealed
by a hill or an obstructed curve.
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.
A patrol car is approaching from the other
direction, sampling traffic with instant-on
radar. Such alerts should be taken seriously.
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.
Alert
The V928i alerts slowly for a while and then
abruptly jumps to a strong alert.
The V928i alerts intermittently. Rate and
strength of alerts may be inconsistent or vary
wildly.
The V928i alerts intermittently. Rate and
strength of signal increases with each alert.
The V928i gives an X-band, or K-band alert
intermittently.
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 radar, your V928i 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 V928i’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).
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 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 V928i can display are listed on the
facing page.
From the factory, your V928i is
programmed with SWS decoding OFF. If
SWS is used in your area, your V928i will
display the safety messages associated with
the signal. If you wish to detect this system,
use the Programming feature to turn the
V928i’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
the V928i’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
unequipped with these transmitters. As
Safety transmitters become more prevalent
(the number of operating transmitters
is growing every day), these Safety radar
signals will become more common.

Troubleshooting
Problem
The V928i beeps briefly at the same
location every day, but no radar
source is in sight.
The V928i does not seem sensitive
to radar or laser.
The V928i did not alert when a
police car was in view.
The V928i did not provide a Safety
signal while within range of an
emergency vehicle.
The V928i’s display is not working.
The V928i’s audible alerts are less
loud after the first few alerts.
The V928i bounces or sags on
windshield.
The V928i’s power-on sequence
reoccurs while you are driving.
Solution
• An X or K-band motion sensor or intrusion alarm is
located within range of your route. With time, you will learn
predictable patterns of these signals.
• Make sure that windshield wipers do not block your V928i’s
radar antenna and that the laser lens is not behind tinted
areas.
• Determine if your vehicle has an Instaclear®, ElectriClear®
or solar reflective windshield which may deflect radar or laser
signals.
• Your V928i may be in City Mode.
• VASCAR (Visual Average Speed Computer and Recorder) a
stopwatch method of speed detection, may be in use.
• Officer may not have radar or laser unit turned on.
• Safety transmitters may not be commonly used in your area.
• Press the BRT button to deactivate Dark Mode.
• The V928i is in AutoMute Mode. See page 8 for details.
• The V928i is not making contact with the windshield
to provide stability. While holding down the V928i’s
QuickMount button, slide the V928i toward the windshield so
that the back top edge makes firm contact.
• A loose power connection or dirty lighter socket can cause
the V928i to be briefly disconnected.
Problem
Your 14-year old son has changed
all 6 of the Programming options.
The V928i will not turn on.
The V928i feels very warm.
Solution
• You can return all of the programming options to the
factory defaults by holding down the CITY and BRT buttons
while you turn the V928i on.
• Check that the power is ON.
• Check that vehicle ignition is ON.
• Check that vehicle lighter socket is functional.
• Try the V928i in another vehicle.
• It is normal for the V928i to feel warm.
