9.4 Diagnostic list
If two or more diagnostic events occur simultaneously, only the diagnostic message with
the highest priority is shown. Additional pending diagnostic messages are shown in the
Diagnostic list submenu . The status signal dictates the priority in which the diagnostic
messages are displayed. The following order of priority applies: F, C, S, M. If two or more
diagnostic events with the same status signal are active simultaneously, the numerical
order of the event number dictates the order of priority in which the events are displayed,
e.g.: F042 appears before F044 and before S044.
