ALERTS
ALERT MESSAGES
If the transponder detects a problem, the screen will indicate
WARNING and a brief statement of the problem. Depending on
the nature of the problem, your transponder may not be replying
to interrogations. Note the message on the screen and pass that
information to your avionics maintenance organization. The
WARNING message should clear when the event has cleared.
Press CLR to clear the message at any time; if the fault is still
present the message may reappear.
FAULT ANNUNCIATION
If the transponder detects an internal failure, the screen will
indicate FAULT and a brief statement of the problem. No replies
will be made to interrogations when a fault is detected.
Some FAULT indications can be recovered by switching the
transponder off and back on again, although in all cases a FAULT
code implies that there is a fault with the transponder or the
installation. Note the FAULT message at the bottom of the
screen and pass that information to your avionics maintenance
organization.
