11.7 AIS Alarms

In addition to the dangerous target alarm previously described, the system generates
an alarm when a dangerous target becomes a lost target i.e. its signal has not been
received for 20 seconds.
Your AIS receiver generates local alarms which are displayed and sounded on your C-
Series display whenever an alarm condition exists on the unit.
