Alarms are used to alert you to a situation or hazard requiring your attention. Alarms are triggered
by system functions and external devices connected to the MFD (Multifunction Displays). Alarms
are displayed on all networked MFDs.
Alarms are color coded to signify their severity:

due to a potential or immediate danger to life or vessel. Dangerous alarms are accompanied by an

alarms may remain active whilst the alarm condition persists but will not trigger further onscreen or
audible notifications.
Warning alarms

used to signify that there has been a change in situation that you need to be aware of. Warnings
