Caution indicates the existence of abnormal conditions
on the aircraft that may require pilot intervention. A
flashing "CAUTION" softkey annunciation and a single
aural tone (one chime) are used to alert the pilot of any
cautions. The flashing "CAUTION" annunciator continues
to flash until acknowledged by the pilot (by pressing the
CAUTION softkey).
Figure 2-77 Caution Softkey Annunciation
An advisory provides general information to the
pilot that may not need immediate attention. A flashing
"ADVISORY" softkey annunciation (no aural tone) is
used to alert the pilot of any message advisories. The
flashing "ADVISORY" annunciator continues to flash until
acknowledged by the pilot (by pressing the ADVISORY
softkey).
