Beltronics Laser Pro 904 Owner's Manual - Page 6

General Operations/Disarm Function 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. 6
