General Operation

Once you have BEL LaserPro

904

properly installed, you’re ready for
unencumbered travel. Assuming
LaserPro

904 is “hard wired” into

your vehicle’s electrical system,
each time you start your vehicle,
LaserPro

904 will start up.

Conversely, each time your shut
your vehicle off, LaserPro

will

shut down. When an alert is
received, LaserPro

904 will

confirm a traffic Laser encounter
from 
the front or rear. A Laser signal
targeted at the transceivers
mounted at the front of your
vehicle will trigger an urgent
audible alert and the illumination
of the red “F” (Front) LED,
coupled with the three blue LEDs
ramping left to right; conversely, a
signal targeted at the rear
transceiver will set-off an urgent
audible alert, coupled with the
illumination of the red “R” (Rear)
LED, and the “ramping” of the
blue LEDs from right to left.

Generally, a Laser alert is very
quick. Always remember to
respond to any alert LaserPro

904 displays. 

Once an alert is received, it is
recommended that you confirm
your vehicle’s legal speed and
Disarm your LaserPro

904 

from further returning a
“blocking” signal to the Laser
source. Five seconds should be
ample time for you to:

a) Verify your vehicle speed; 

b) Press the DIS (DISARM) 

button once you’re in 
compliance with the 
posted speed limit.

Disarm Function

Pressing 

DIS

(Disarm) will

terminate the LaserPro

904

transceivers from further 
returning a blocked signal to the
Laser gun, and make certain
countermeasures do not 
interfere with the officer’s traffic
Laser signal.

Once the 

DIS

(DISARM) button

has been pressed, LaserPro

904 will display a flashing green
power LED. This flashing green
LED serves to confirm that
LaserPro is no longer “blocking”
the Laser signal. This “monitoring”
mode will last for 60 seconds.
