Transponder Operation

The GTN 6XX will operate as a control head for remotely connected optional,
compatible transponders.
NOTE: The transponder control panel on the GTN will only contain the
Ground key when the GTN is interfaced with a GTX 33/330 with software
versions prior to 8.00.
NOTE: Starting the GTN with a Flight Stream 510 wireless datacard in the
slot may cause the control panel to be temporarily unavailable on the
start-up screens during unit power up.
