ALERT MESSAGE BAR
Alert messages are shown on the lower right corner of the IFD
using a background color corresponding to the level of the alert.
If more than one unacknowledged alert is active, the most recent
alert with the highest level will be shown.
Warning Message
Pressing the “CLR” bezel key or touching the message bar on the
display will acknowledge the message, causing the message bar
for that alert to disappear. Note that acknowledging the message
does not eliminate the condition that caused the alert. However,
some alert messages are issued in response to an event, and
acknowledging the alert effectively clears the condition.
After all active messages have been acknowledged, the AUX
lamp will remain illuminated with the color of the message with
the highest level.
Alerts are either “global” or “local” in nature. In a single IFD
installation, the difference is irrelevant. In a dual IFD installation,
however, global alert messages are displayed on all IFDs,
whereas local alert messages are displayed only on the issuing
IFD. A global message can be acknowledged on any IFD and
that will cause the message to disappear on all IFDs. Because a
local message is only displayed on one IFD, it must be
acknowledged on the same IFD. The table of system CAS
messages that appears later in this section denotes global
messages using an asterisk.
