1.9 License Requirements
The Telecommunications Act of 1996, effective February 8, 1996, provides the Federal Communications
Commission (FCC) discretion to eliminate radio station license requirements for aircraft and ships.
GTR/GNC installations must comply with current transmitter licensing requirements. In the US, to find out
the specific details on whether a particular installation is exempt from licensing, please visit the FCC
website http://wireless.fcc.gov/aviation
. If an aircraft license is required, make application for a license on
FCC form 404, Application for Aircraft Radio Station License. The FCC also has a fax-on-demand
service to provide forms by fax. Outside the US, contact the responsible telecommunication authority. The
GTR/GNC owner accepts all responsibility for obtaining the proper licensing before using the transceiver.
The maximum transmitting power, modulation identification, and frequency band information may be
required for licensing, see section 1.4.4.
CAUTION
The VHF transmitter in this equipment is guaranteed to meet FCC acceptance over the
operating temperature range. Modifications not expressly approved by Garmin could
invalidate the license and make it unlawful to operate the equipment.
