Number segments and status indicator icons.
POWER
When POWER appears, the power is on.
RFI
The radio frequency interference (RFI) icon indicates that excess
RFI energy is present. The radar automatically inhibits all speed
measurements. No new speeds display in the display window or
transmit via the serial port while this icon is active, and if the system
is displaying a locked speed, the speed will remain locked. When
the RFI condition no longer exists, the system will resume normal
operation. Possible causes of this condition are the patrol vehicle’s
FM communications, proximity to radio stations and other broadcast
equipment.
LOW BAT
The LOW BAT icon indicates that your vehicle’s battery (or your
separate battery pack) may be low on power. The system will not
transmit or display any new speeds while LOW BAT appears, and
if the system is displaying a locked speed, the speed will remain
locked.
