Note
It may take up to 30 seconds for the 3G modules alarms to clear when
starting up the boards. The boards are operational; however the voltage
sensing alarms can take up to 30 seconds to clear. This length of time to
clear the alarms is due to the fact that the 3G modules are using new
voltage averaging algorithms in the 908 Micro controllers to compare
and verify all voltages.
