Level 5 self-test provides enunciation of the alerts (cautions and warnings) recorded over the last 10 flight legs. Level 5 self-
test is initiated by pressing the cockpit self-test button within 3 seconds of the end of level 4 self-test. The process is
described in Figure 6.10.6-7.

Otherwise the message “NO WARNINGS” will be annunciated.

proceeding to level 6 self-test.
