c) Select 121.15 MHZ on COMM1
d) Transmit for a period of 20 seconds
e) Verify that the flag does not come into view
f) Repeat steps d) and e) for the following frequencies:
121.175, 121.20, 131.250, 131.275 and 131.300
g) Repeat steps c-f for all COMMs installed in the aircraft
h) If the NAV flag comes into view, refer to Section 2.1.5 for options to improve

4.3.10 VHF COMM CHECK
A flight test is recommended after the installation is completed to insure satisfactory
performance. To check the communications transceiver, maintain an appropriate
altitude and contact a ground station facility at a range of at least 50 nautical miles.
Contact a ground station close in. Press the squelch disable button to defeat the
automatic squelch feature and listen for any unusual electrical noise which would
reduce the COMM receiver sensitivity by increasing the squelch threshold. If possible,
verify the communications capability on both the high and low end of the VHF COMM
band.
SECTION 5 CERTIFICATION
The GNC 300 is certified for IFR enroute, terminal and non-precision approaches.
The GNC 300's initial certification was accomplished via a STC by GARMIN in a
Mooney M20J. See Appendix C for a copy of the STC.
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 Mooney installation will be Follow-On.
SECTION 6 CONTINUED AIRWORTHINESS
Maintenance of the GNC 300 is on condition only. Periodic maintenance of the GNC
300 is not required.
