Messages and Unit Settings
The GPS 155XL’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
GPS 155XL needs to alert you to a navigation or system message, 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., poor
GPS coverage). For a complete list of GPS 155XL messages, please see Appendix D.
To view a message, press M. Press M again to return to the previous page.
The GPS 155XL’s settings submenu is also accessed from the M key.
To view the settings submenu, press and hold M for more than 2 seconds.
Once the settings submenu has been accessed, the following setup pages are available
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
• Map datums • I/O Settings (channel 2 only)
To access the settings submenu pages, press and
hold the
M key for two seconds. The GPS 155XL
will return to the last submenu viewed the next
time you access the unit settings.
To view a message, press M.
