Garmin GNC 300 - Manual (Page 11)

Database Confirmation Page
Welcome Page
The GARMIN GNC 300 is a powerful navigational tool that provides pilots with accurate navi-
gational data and communication capability, along with non-precision approach certification in the
IFR environment. The Takeoff Tour is designed to familiarize you with the operation of the GNC
300, including powering up the unit, changing frequencies, entering data and performing a sim-
ple direct-to, and a limited introduction to the ‘Nearest’ functions. In addition, this section also
briefly covers the position, CDI and frequency pages available from the NAV key. These pages will
be used for most of your in-flight navigation.
The Takeoff Tour assumes that the GPSCOM and antennas have been properly installed
and you have not changed any of the GNC 300’s default settings. If you have changed any
of the factory default settings (position format, units of measure, selectable fields, etc.), the
pictures used may not match your configuration. Prior to using your GNC 300 for the first
time, we recommend that you taxi to a location that is well away from buildings and other
aircraft so the unit can collect satellite data without interruption.
Powering up the GNC 300
The GNC 300’s power and volume are controlled using the
B (power/volume) knob at the
bottom left of the unit. Rotating it clockwise will turn the unit on and increase the radio vol-
ume. This knob also locks the NavData
® card (included with your unit) in place so that it may
not be removed during operation. After turning the unit on, a welcome page will be displayed
while the unit performs a self test.
The database page will appear, showing the current database information on the NavData
card, with the valid operating dates, cycle number and database type indicated. Databases are
updated every 28 days and are available for one-time or subscription purchase.
