Messages and Unit Settings
The GNC 300' s MSG key provides access to system messages and allows you to
customize your GPSCOM to your own preferences through a settings submenu.
Whenever the GNC 300 needs to alert you to a navigation, communication or system
message, the annunciator light next to the M key will flash. Some messages are
advisory in nature (e.g., the arrival and countdown alarms), while others may require
your immediate attention (e.g., a stuck microphone message). For a complete list of
GNC 300 messages, please see Appendix D.
To view a message, press M. Press M again to return to the previous
page.
The GNC 300' s settings submenu is also accessed from the MSG key.
To view the settings submenu, press and hold the M key for more than 2
seconds.
Once the settings submenu has been accessed, the following setup pages are avail-
able by rotating O with the flashing cursor inactive:
• CDI scale settings
• Nearest airport search
• Display intensity settings
• Navigation units
• Map datums
Section 7
• Mag. var./arrival alarm settings
