9.3 System Status Indicators and Reset Button
As viewed from the front of the unit, the DM3X Transponder utilizes LEDs to indicate system status. During system
start up, the LEDs will first blink momentarily then indicate the current status of a variety of parameters on the DM3X
Transponder. The LEDs indicate alarms, RF power level status, battery string connectivity and communications activity
with the network. A description of each LED follows.
