12.1 Status LED states
The status LED on the transmitter indicates whether or not alarms are active. If alarms are
active, view the alarm list to identify the alarms, then take appropriate action to correct
the alarm condition.
Your transmitter has a status LED only if it has a display.
If the transmitter has a display and LED Blinking is disabled, the status LED does not flash to
indicate an unacknowledged alarm.
