Honeywell Bendix/King KMD 550 Pilot's Manual Addendum page 18

If we reduced our altitude to 8,400 Ft MSL then we would generate a
Terrain Warning. The following figure shows an example of how a terrain
warning looks on the Terrain Display page.
Depending on how your EGPWS is configured it may automatically
reduce the range scale in the event of a warning to show more detail on
the nearby terrain.
Other display pages of the KMD 550/850 can be selected with confi-
dence since the EGPWS will always be running in the background as
indicated by the gray terrain icon. If the EGPWS issues a warning or
caution, a pop up message will appear on the active display page similar
to that shown in the following figure. In some installations, the KMD
550/850 will be configured to automatically pop-up the Terrain Page in
this situation.
