7.5 GTX 33 Transponder
Original GTX 33 is Reinstalled
No software or configuration loading is required if the removed GTX 33 is re-installed. This does not
include units that were returned for repair as their software and configuration files are deleted during the
repair testing process. Continue to GTX 33 Test (Section 7.5.2).
Original GTX 33 Installed in Opposite Locations for Troubleshooting
No software loading is required if the original GTX #1 and GTX #2 are installed in opposite locations.
Continue to Transponder Configuration (Section 7.5.1).
New Repaired or Exchange GTX 33 is Installed
If a new repaired or exchange GTX 33 is installed, the correct software and configuration files must be
loaded to the unit. See Section 3.9. Also enter the aircraft registration number in the GTX Config page
after loading software and configuration files. Then continue to Transponder Configuration (Section
7.5.1).
