LICENSE REQUIREMENTS
If any of these devices are connected to a personal computer used in home or in office, then the four following
paragraphs are applicable.
These devices comply with Part 15 of the FCC limits for Class B digital devices. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful interference to other equipment, which can
be determined by turning the equipment off and on, the user is encouraged to try and correct the interference by
relocating the equipment or connecting the equipment to a different circuit than the affected equipment.
Consult an authorized dealer or other qualified avionics service technician for additional help if these remedies
do not correct the problem. These devices comply with Part 15 of the FCC rules. Operation is subject to the
following conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
These units do not contain any user-serviceable parts. Repairs should only be made by an authorized GARMIN
service center. Unauthorized repairs or modifications could void your warranty and your authority to operate this
device under Part 15 Regulations.
The FCC requires GARMIN to inform users that these units meet the more stringent requirements "For Home or
Office Use".
The following guidance is provided to help ensure the proper licensing of the GNC 300XL Comm.
1. The Telecommunications Act of 1996 effective February 8, 1996 provides the FCC discretion to eliminate
radio station license requirements for aircraft. At present, an individual license to operate the GNC
300XL aboard a private aircraft is not needed in many circumstances. Please see FCC Fact Sheet PR5000
or contact the FCC at 1-800-322-1117 for more information.
2. No license change is required for aircraft that already have a station license per FCC 404 Instructions
dated 1994.
3. If an aircraft license is required or desired, contact the FCC at 1-800-322-1117 to request FCC form 404,
“Application for Aircraft Radio Station License,” to apply for FCC authorization. The FCC also has a
"Fax on Demand" service to provide forms by fax at 202-418-0177.

CERTIFICATION
The GNC 300XL/GPS 155XL is certified for IFR enroute, terminal, and non-precision approaches. The GNC
300XL/GPS 155XL initial certification was accomplished via an STC by GARMIN in a Piper PA32 aircraft. See
Appendix C for a copy of the STCs.
All installations must be certified. For more information, see FAA Advisory Circular "Airworthiness Approval of
Global Positioning System (GPS) Navigation Equipment for use as a VFR and IFR Supplemental Navigation
System," Appendix 1. All new certifications after GARMIN's Piper PA32 installation will be "Follow-On."
1.4.1
German Certification
For installations required to meet German regulation REG TP 321 ZV 034, Lowpass Filter (GPN 330-00157-00)
must be installed on the GNC 300XL COM RF connector, J4, instead of the GPS Notch Filter (GPN 330-00067-00).
