Once your unit has completed the power-up test sequence, the
audio level can be adjusted by holding the ⁄ button down.
As you hear the audio level change, the digits ‒ in the Digital
Display provide a visual reference of the audio level.
To reverse the direction in which the audio level increases/
decreases, briefly release, then hold down the ⁄ button again.
 (Dim/Dark) Button
The  button allows selection of a dim or dark setting for
all leds and the Digital Display. To engage dim mode, press
the drk button once.A single “beep” confirms your selection.
To completely cancel the illumination of all leds, press drk a
second time.You’ll notice a horizontal bar segment remains
dim to indicate your unit is receiving power. To return to a full
bright setting, press the drk button a third time; two “beeps”
confirm this selection. Use of the drk button does not affect
audio alerts.
Important—if you press the the  button and do not receive
audible confirmation, the audio level has been set too low.
 (Audio Mute) Button
Continuous Audio Alert Pattern
Your unit has been preset at the factory to provide an X, K, Ka
or Laser audio alert and Digital Voice announcement of the
signal detected. Digital Voice prompts are provided once after
the initial audio alert. This standard setting is often preferred
when background noise in a vehicle is loud.
Automatic Mute Audio Alert Pattern (Radar)
To engage automatic muting, press the  button once when
the unit is not alarming.A single “beep”and a decimal point in
the upper left corner of the Digital Display confirm automatic
mute mode has been engaged. The alert pattern when this mode
is activated consists of a short X, K or Super Wideband Ka
audio alert followed by the Digital Voice announcement of the
signal detected (if feature is engaged).AftertheDigitalVoice
announcement, a “clicking” tone keeps you quietly informed
for as long as the signal is present. This “clicking” becomes

12892 Bel Express 926/916 Man 4/26/01 2:44 PM Page 6

more rapid as the strength of the Radar signal increases. With
this mode engaged, the automatic mute mode enables you to
conveniently monitor extended encounters without having to
manually mute or adjust the volume setting. To return to the
continuous audio alert pattern, press the  button a second
time while the unit is not alarming. Two “beeps” and no
decimal point in the upper left corner of the Digital Display
confirm you have cancelled automatic mute mode.
Manual Muting of Audio Alerts (Radar & sws™)
Regardless of the  mode selected (continuous or
automatic mute) the X, K, Super Wideband Ka and sws™
audio alerts can be completely muted by pressing the 
button during an alert. Once the alert has passed, the unit will
revert to the previous aud setting (continuous or automatic
mute).
Note—because Laser alerts are not lengthy or sustained, muting
is not required (see page 17).
 (City X/Highway) Button
The city X mode has been designed to effectively reduce
unwanted audio alerts caused by intrusion alarms, door
openers, and other devices which share X band with police
Radar—without reducing sensitivity. Signals from non-police
Radar sources are frequently encountered in urban and
suburban areas, making use of this mode ideal in these areas.
Pressing the  button once engages the city X mode
which is confirmed by a “C” in the Digital Display and a
single audio “beep”. Pressing the  button twice returns you
to highway mode; a double “beep” and illumination of “H”in
the display will confirm this selection.With  engaged,
weak X band signals encountered will produce no audible
alert until the signal strength reaches a preset level. However,
visual alerts are processed the instant an X band signal is
detected, keeping you quietly informed. Since most “false” X
band signals are weak, the use of the city mode allows you to
drive out of their range before they reach the preset level and
trigger a full audio alert. In contrast, signals from X band
traffic Radar are generally stronger and will exceed the preset
level, causing a full X band audio alert.

12892 Bel Express 926/916 Man 4/26/01 2:44 PM Page 7

Activating the City X Mode will not change Super
Wideband Ka, K or instant-on X band Radar alert patterns.
Note—the cty mode does not change the presentation of alerts
for Laser, sws™or vg-2 signals.
City ALL (X/K/Ka)-Model 926 only
City ALL provides an alternated approach for improving X,
K and Ka band selectivity and is ideal for use in areas with a
high level of microwave trasmissions which can cause falsing
on all three bands. To engage City X/K/Ka mode, press 
until the Dispay shows a capital “A”. Once engaged, weak X, K
or Super Wideband Ka signals encountered will provide no
audible alerts until the signal strength reaches a preset level.
Visual alerts are processed the instant an X, K or Super
Wideband Ka signal is detected, keeping you quietly informed.
Reset to Factory Settings
You can reset your unit to factory settings for volume, ,
, and Selectable Features. With the unit ,press

General Guidelines
Do not mount your unit directly behind windshield wipers or
mirrored sunscreens which block Radar and Laser signals
and substantially reduce warning range. Unlike “after market”
mirrored sun-screens, regular tinted glass does not affect
Radar reception.
Radar signals are also reflected by the “heated windshields”
known as Instaclear®and ElectriClear®available as an option on
some vehicles. This type of windshield makes any dash, visor or
windshield mounted detector ineffective. (If in doubt, check with
an appropriate dealership to see if this applies to your vehicle.)
To achieve optimum performance, regardless of which
mounting position you choose, follow these basic steps:
12892 Bel Express 926/916 Man 4/26/01 2:44 PM Page 10

. Consider occupant safety when selecting a mounting location.
Choose a location where the unit will not be hazardous in
case of an accident.
. For optimum detection, position your unit with a clear,
unobstructed view of the road from the front and rear.
. Do not allow the unit to make contact with the windshield.
This will eliminate unnecessary vibration.
. Avoid placing your unit in direct sunlight. During the summer,
the interior of an enclosed vehicle can sometimes reach
temperatures that will cause premature aging of the unit.
. Your detector is not waterproof; exposure to water may cause
damage.
Dash Mounting
. Select an area that is relatively level, clean and dry.Adhere the
soft portion of the enclosed hook and loop fastener to this area
and the corresponding hard portion to the bottom of your unit.
. Fasten unit to dash by placing
hook and loop pieces together.
Mounting Brackets
The visor bracket is fully
assembled. To assemble the
windshield bracket, follow this
diagram.
Visor Mounting
. Remove the mounting bracket
cover on top of the unit by pressing on the raised dots and
pushing outward. Store the cover in a safe place.

12892 Bel Express 926/916 Man 4/26/01 2:44 PM Page 11

. Slide the visor bracket onto the top of the detector until it
snaps into place. Clip the detector to the edge of the sun visor
nearest the windshield.
Windshield Mounting
1. Remove the mounting bracket cover on top of the unit by
pressing on the raised dots and pushing outward. Store the
cover in a safe place.
. Clean the selected windshield area, position the suction-cup
mount on the windshield, and press firmly on each suction
cup to secure it in place.
3. Use a screwdriver or a small coin to adjust the suction-cup
mount until the base plate is level.
. Slide detector onto base plate until it snaps into place.
Note—some vehicles have a plastic coating on the inside of the
windshield designed to protect occupants in case of an accident.
Use of the windshield bracket on this type of windshield can
permanently mark the surface. Check with your dealer if you
are unsure whether your vehicle is equipped with this type of
windshield.

Power Jack
Yo u r  detector operates on . volts  and receives power
from the cigarette lighter socket. The cigarette lighter plug has
been designed to fit universally in all sockets. The lighter
socket must be clean and well grounded for proper operation.
Fuse Replacement
If your unit is not operating because the fuse has blown,
replace the fuse as follows:
1. Carefully unscrew the tip of the cigarette lighter plug.
2. Remove the tip from the cigarette lighter plug, followed by the
old fuse.
Note—the tip is in two pieces. Be careful not to lose either piece
or the spring inside the holder.
3. Replace the fuse with a -amp,  fuse. (See Accessories,
page 23, for proper replacement.) Defeating the fuse protection
can damage your unit or your vehicle’s electrical system and
will void your warranty.
4. Press the tip of the plug into the body, and screw back into place.

Three Radar Frequencies
Three microwave frequencies have been allocated by the 
(Federal Communications Commission) and are used for
traffic Radar: X, K and Super Wideband Ka.Your EXPRESS
detector provides detection of all known radar traffic devices.
Tota l Track ing L aser™(ttl™)
Unlike Radar signals, which are highly reflective, Laser signals
have very poor reflective characteristics. Many of today’s Laser
detectors do not have the high sensitivity necessary to detect

Laser within a large“field of view”.express 926 and express
916 incorporate ’s number one rated Laser detection. Twin
Laser ports detect energy far outside the main Laser beam—
including off-axis signals—providing the largest achievable
° “field-of-view”. The alerts received by your unit are the
same whether they are received from the front or rear.
Safety Warning System®(sws™)—What is it?
The Radio Association Defending Airwave Rights, Inc.
(.....) conceived and developed the Safety Warning
System®.The concept behind this system is to warn motorists of
potential road hazards by employing Safety Warning System®
transmitting devices in areas such as construction zones,
accidents sites and detours. These sws™transmitters operate
within the  zportion of the K band frequency and
broadcast unique, coded signals which are detected by your
express 926 or express 916.
interpretation of alerts
Radar Alerts
The alerts provided by your unit are affected both by the type
of transmission (continuous wave or instant-on) and the
position of the Radar source. Generally, when you drive closer
to a Radar source, the intensity of the received signal increases,
resulting in a higher number appearing in the Digital Display
and a corresponding increase in the audio alert rate. Described
below are five common types of Radar encounters and the
alerts you will typically receive.
1. Stationary or moving Radar, straight ahead aimed in your
direction.

12892 Bel Express 926/916 Man 4/26/01 2:44 PM Page 14

Since Radar signals travel in a straight line, this Radar
encounter potentially offers maximum warning range. Once
the signal is received, the initial warning consists of the X, K
or Super Wideband Ka audio and visual alerts and the simul-
taneous illumination of a signal strength digit. The actual
digit displayed will depend upon the strength of the signal
received.As the strength of the Radar signal increases, the
audio alert becomes more rapid and the signal strength digit
will progressively increase. Assuming the Radar signal
remains uninterrupted, the audible and visual alerts will
clearly indicate a “weak” signal becoming stronger as you
drive closer to the Radar source. Remember, when the police
Radar source is moving toward you, the Radar signal strength
will increase much more rapidly than if you are approaching a
stationary source.
.Stationary Radar aimed around a corner
Under this circumstance, reaction time is considerably
reduced. Since the Radar signals are transmitted across your
line of travel, there is generally no signal available to receive
until you are relatively close to the source. Once an alert is
received, expect the strength of the signal to increase very
quickly.Advanced warning in this situation may be reduced.
3. Stationary Radar concealed by the crest of a hill aimed in your
direction.

12892 Bel Express 926/916 Man 4/26/01 2:44 PM Page 15

Radar signals travel in a straight line and do not pass through
earth. Consequently, police Radar aimed at the crest of a steep
hill cannot be received until you are at or near the top.
Warning time may be minimal (as in situation #2) since a
strong signal is not present until you are near the crest of the
hill. At this point, you may be nearly in the police officer’s line
of sight.When cresting a hill, a weak initial alert followed very
quickly by a full alert is typical. This alert pattern requires
prompt attention.
.Moving Radar behind you, traveling in the same direction.
Police Radar signals transmitted from behind your vehicle can
be received when reflected by objects in front of you such as
large signs, bridges and trucks.As you drive, the size and con-
figuration of these objects are constantly changing causing the
strength of any reflected Radar signal received to vary.A strong,
uninterrupted alert indicates the patrol car is close behind.
Instant-On/Pulsed Radar
This type of signal appears suddenly when a Radar unit is
“triggered”. The instant-on alert consists of an intense, three
second X, K or Super Wide band Ka audio “burst”, coupled
with the illumination of the digit “9” and the corresponding
band indicator.
Typical False Alert (Radar)
Ideally, a Radar detector should only alert in the presence of
police Radar. However, because other devices share X band
with police Radar, false alerts sometimes occur. Generally, a
false signal produces only a short audio and visual alert. Since
they are most often weak, it is possible to drive out of the

12892 Bel Express 926/916 Man 4/26/01 2:44 PM Page 16

signal’s range very quickly and receive only a brief alert.
Although many times the probable source of the false signal
can be identified (supermarket, bank, commercial building,
etc.), caution is advised until the source can be confirmed.
The X band alert pattern caused by a non-police source can
look like the initial alert produced by actual police Radar. For
this reason appropriate action is required any time an alert is
received.
Laser Alerts
When Laser is detected, a flashing “L”willappearinthe
Digital Display.
If a vehicle is a long distance from the source of Laser pulses,
fewer pulses will generally be received. The closer the vehicle
is to the source of Laser pulses, the greater the likelihood of
receiving a steady stream of Laser pulses. The reason for this
is the aiming stability of the Laser gun and the fact that it is
impossible to hold the gun absolutely still. Any movement of
the gun results in motion of the beam at the target. The further
the target, the greater the displacement of the beam and the
shorter the dwell time of the beam at the target point. There-
fore, there is the possibility of receiving only a few Laser pulses.
Due to these characteristics, all Laser alerts received from
your unit should be taken seriously.
vg-2 Guard®Alert
Whenever your express unit detects signals from the
Interceptor vg-2 (Radar Detector Detector), the vg-2 Guard®
feature engages, alerting you to the presence of the interceptor
vg-2.(vg-2 Guard®must be selected on—see page 8 for more
information on Selectable Features).Adistinct,2-second
audio warning coupled with the Digital Voice announcement of
“vg-2 Alert” and the flashing of the “H”, or “A” (926 only) in
the Digital Display confirms activation of the vg-2 Guard®
feature. This flashing continues for as long as vg-2 Guard®is
activated. During the vg-2 alert your unit does not detect
Radar or sws™ signals. However, the presence of the
Interceptor vg-2 indicates that traffic is being monitored and
speed measurements may be taken. When the “H”or“C”stops

12892 Bel Express 926/916 Man 4/26/01 2:44 PM Page 17

flashing, the vg-2 alert is over and your unit resumes
scanning for Radar and sws™signals.
Note—activation of - Guard®does not affect detection of
Laser signals.
Safety Warning System®(sws™)Alerts
With the Safety Warning System™feature on and an sws™
transmitter in use, your detector will alert with a unique,
2-second sws™audio tone coupled with the illumination of the
sws™led and the sws™message category digit (1–5).(Ifsws™
Digital Voice is on (model 926 only) the appropriate message
is heard twice, immediately after the 2-second tone.) After the
Digital Voice Message, a “clicking” pattern is provided for as
long as the the signal is present.

Conditions that Affect Radar Alerts
If you feel your unit is not alerting properly, keep in mind that
there are many conditions that influence the intensity or
duration of an alert:
. The police are using instant-on/pulsed Radar, in which case
no signal is transmitted until visual contact has been made
with your vehicle. For detection of this signal, you must rely
on reflected signals from Radar directed at traffic traveling
ahead of you.
. The police Radar unit is positioned perpendicular to the road,
around a curve, or just over the crest of a hill, thus, significantly
reducing the reception range.
. The highway traffic between your vehicle and the police Radar
source is heavy. This blocks/reflects transmitted signals. The
presence of several large trucks between you and the police
Radar unit could also significantly reduce reception.
. Rain or humid weather conditions can absorb transmitted
signals before they reach your vehicle, again reducing detection
range.
. The police Radar unit is not properly tuned and is transmitting
outside the fcc allocated X, K or Super Wideband Ka frequency
ranges.
Conditions that Affect Laser Alerts
If you feel your unit is not properly alerting to the presence of
Laser signals, keep in mind that rain, fog, high humidity and
traffic conditions can affect the range that the Laser beam can
be detected. ing
