Scanning
The Scout 2 is designed to be hand-held in a steady position. Moving or “scanning” the antenna past stationary
objects can cause the system to detect motion. Obtaining a speed reading from scanning will not happen when you
properly use the radar and this considered deliberate misuse of the system.
Vehicle Ignition Interference
The Scout 2 has been designed to operate from their internal battery pack but can be powered from the vehicle’s USB
receptacle. When connected to the USB receptacle it should be noted that some vehicles exhibit excessive alternator
noise at the USB receptacle. In these rare cases, the radar can exhibit erratic readings, especially when the vehicle’s
electrical system is operated under heavy load. Wiring an accessory USB outlet directly to the battery minimizes the
eect. If you are operating o of the radar’s internal batteries, then vehicle ignition interference will not be a factor.
If you suspect that there is an interference with your vehicle’s electrical system, contact local Decatur Electronics
factory authorized service centre for more information.
Testing the Device
Operator-Initiated Self Test
Pressing the TEST button starts a comprehensive system self test, which allows the operator to verify the display and
runs a target speed simulation. The self test includes:
Display Test–The display test veries that the digits and status icons are working correctly and that none of the
pixels in the number segments are damaged.
Circuitry Test–The system checks the internal circuitry. If the unit passes all internal checks, the message PASS will
be displayed. If an error should occur then FAIL will appear in the display window.
Speed Simulation Test–The radar veries speed accuracy using synthesized Doppler frequencies corresponding
to a series of four simulated speeds: 40, 70, 100, and 130 KPH.
If the device does not display the expected speed, contact your local Decatur Electronics factory authorized
service centre at 800.428.4315 to arrange for service.
