GTX 345.
The ADS-B Out system is a single point of entry system for
Mode 3/A code, Flight ID, IDENT functionality and
activating or deactivating emergency status for both
transponder and ADS-B Out functions. Parameters are set
in the transponder at the time of installation and are
automatically incorporated in ADS-B Out broadcasts.

vary based on local regulations.

the lower left corner of the GTX 345 when the
ADS-B TX is manually turned off or when there
is a transmission malfunction.
