11.1 Alarms
Alarms are used to alert you to a situation or hazard requiring
your attention.
Some examples of alarms are:
• Anchor alarm — Used when anchored, this alerts you to
a change in depth which could mean that the chain length
requires adjusting.
• Depth and speed alarms — These alarms alert you when your
depth or speed moves outside of specified limits, for example
a minimum depth.
• MOB (Man Overboard) alarm — Received from an MOB
system.
When an alarm occurs, a message is displayed and an audible
alarm may sound.

alarms on and off, SeaTalk
