CDI key again to cycle its operation.
 "Ignore CDI key" has been selected
on the MAIN CDI/OBS CONFIG
page.
 The 400W Series unit has detected
excessive display backlighting
temperature. The backlighting has
been automatically dimmed to
reduce the temperature.
 The unit has detected a failure in its
communications transceiver.
 Internal system-to-system
communication between the main
processor and the COM transceiver
has failed. Operational status of the
COM transceiver is unknown.

communications transceiver. The
COM transceiver may still be usable.

 The remote COM transfer switch is
stuck in the enabled (or "pressed")
state.
 The COM flip-flop key is stuck in the
enabled (or "pressed") state.
 The unit has detected excessive unit
temperature. The COM transceiver
transmit power has been
automatically reduced to compensate
for the condition.
 Insufficient voltage level
 The configuration information has
been lost or corrupted.
 An attempt to transfer flight plan data
during a unit-to-unit crossfill was
