(6) Power / Fault
Flashes green when the radio is operating normally.
Flashes red when a fault has occurred. Faults are displayed in Cruise
Control under Main -> Diagnostics -> Faults. Faults that are
detected by the radio are:
 Point-to-point destination address equal to source address
 Reserve section of a datagram packet not equal to 0x0000.
 The last time the radio reset was due to a watchdog reset.
When a fault occurs, it is latched for 15 minutes. If after 15 minutes the
alarm has not re-occurred it is cleared. The fault can be cleared manually
by re-powering the radio.

3.5.2 RSSI, Tx Power, Temperature Status (Mode 2, 3, 4)
When in mode 2, 3, or 4 the front panel is used as a bar graph, with the lowest value indicated by all LEDs
off, and the highest by all LEDs on. The bar grows by lighting LED 6 up to LED 1 green. If the top LED is
red, then it indicates that the current value is half way between the listed value and the previous value. Table
5 shows the levels for the bar graph display.
