Neuron activity
The Neuron is a specialized internal microprocessor. The LEDs labeled TX and RX indicate Neuron
activity. These LEDs will be flickering under normal operation.
System Faults
Any system fault will be shown on the display by its fault code as shown below.

A fault can be muted or cleared. Muting the fault only silences the warning tone
for 24 hours
. Clearing
the fault can only be accomplished after the fault is rectified.
