STATUS Light:
The STATUS light blinks when power is applied to the unit.
Regular blinking (once per second) indicates that the XR has successfully
learned a data string and is running properly.
Rapid blinking (3 times per second) indicates that the XR is in Auto-Learn
mode, attempting to interpret a data string.
COM Light:
The COM light flashes on each time the XR receives a character through any
of its COM Ports (including the radio).
RADIO Light:
The RADIO light flashes on when the XR’s radio module receives data. This
light will only illuminate if the radio module is installed.
