The menu items are:

to enable or
OFF
to disable the
Automatic Map Change feature.
2. Press
Enter to activate the selection.
3. When
AUTO
is selected, the unit displays the screens to
set times for switching.

When ESF is used with an FDL channel between units, the

sending a map switch command from end-to-end over the
FDL. Only one end needs to be set to Auto for this to work.
