customize your GPSCOM to your own preferences through a settings submenu.

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.
