3 POST INSTALLATION CONFIGURATION & CHECKOUT PROCEDURE

3.1 Aircraft Station Licensing Requirements

The Telecommunications Act of 1996, effective February 8, 1996, provides the FCC discretion to eliminate radio
station license requirements for aircraft and ships. At the present time, you do not need an individual license to
operate the GTX 320/320A aboard your private aircraft in many circumstances. To find out the specific details on
whether you are exempt from licensing, please see FCC Fact Sheet PR 5000 or contact the FCC at
(800)-322-1117.
If an aircraft license is required or desired, contact the FCC at (800)-322-1117 to request form 404, Application
for Aircraft Radio Station License. The FCC also has a fax-on-demand service to provide forms by fax at
(202)-418-0177.
The GTX 320/320A owner accepts all responsibility for obtaining the proper licensing before using the
transponder.

3.2 Operation

The coverage you can expect from the GTX 320/320A is limited to "line of sight". Low altitude or
aircraft antenna shielding by the aircraft itself may result in reduced range. Range can be improved
by climbing to a higher altitude. It may be possible to minimize antenna shielding by locating the
antenna where dead spots are only noticed during abnormal flight attitudes.
