General
(1)
If the KGX detects a malfunction, the KGX control panel displays the MSG icon in the center of
the LCD. Depending on the nature of the malfunction, the KGX can possibly not be transmitting
ADS-B messages. To view the system messages on the Warning page, push the FN button
four times and WARNING is displayed top center along with a brief description of the fault. The
Warning page is only available when the MSG icon is present.
(2)
When the Warning page is displayed, the KGX control panel continually requests the active
system messages. The MSG icon will remain as shown as long as system messages are
still present.
(3)
The MSG icon is only present when a malfunction is present. A log of system messages
can be accessed using the MPI.
(4)
Refer to Table 4003 for the KGX control panel system messages.
