Operational Alarm
An operational alarm is indicated by all 4 LEDs periodically flashing red (no green flashes). This alarm can indicate the radio has
detected an error which may not be recoverable by the user. Depending on why the operational alarm has occurred, the event log
can be referred to, which may help diagnose why operation alarm is active.
