Messages and Unit Settings
The GNC 300XL’s M key provides access to system messages and allows you to
customize the unit to your own preferences through a settings submenu. Whenever
the GNC 300XL needs to alert you to a navigation, communication or system mes-
sage, the annunciator light (
U) 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 300XL messages, please see Appendix D.
To view a message, press M. Press M again to return to the previous
page.
The GNC 300XL’s settings submenu is also accessed from the M key.
To view the settings submenu, press and hold M for more than two
seconds.
Once the settings submenu has been accessed, the following setup pages are avail-
able by rotating O with the cursor inactive:
• Map page settings • CDI scale settings
• Nearest airport search • Mag. var./arrival alarm settings
• Battery saver • Display screen settings
• Backlighting settings • Trip timer settings
• Navigation units • SUA settings
