License Requirements
CAUTION
The UHF transmitter in this equipment is guaranteed to meet Federal Communications
Commission acceptance over the operating temperature range. Modifications not
expressly approved by Garmin could invalidate the license and make it unlawful to
operate the equipment.
NOTE
For non-US installations consult the local spectrum management agency for
requirements.
The Telecommunications Act of 1996, effective February 8, 1996, provides the FCC discretion to
eliminate radio station license requirements for aircraft and ships. The GTX 3X5 installation must obey
current transmitter licensing requirements. In the US, to find out the specific details on whether a particular
installation is exempt from licensing, visit the FCC website
http://wireless.fcc.gov/aviation.
If an aircraft license is necessary, apply for a license on FCC Form 404,

. The FCC also has a fax-on-demand service to supply forms by fax. The GTX 3X5 owner
accepts all responsibility for obtaining the proper licensing before using the transponder.
