First of all, your equipment should be properly installed with setup, including transponder & GPS. Next, you must be receiving a signal. Finally you should check to make sure your software has been upgraded to version 1.4 or 1.3. If everything is functioning properly, you are receiving a signal & have the proper software - TIS should be working.

If you software has not been upgraded, please contact Southeast Aerospace for your free software upgrade.
