13.13 AIS alarms
The AIS functions generate a number of alarms to alert you to
dangerous or lost targets.
In addition to the dangerous target alarm, 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 multifunction display whenever an alarm condition
exists on the unit.
Local AIS alarms
When the connected AIS unit generates an alarm, your multifunction
display shows a local alarm message and indicates the alarm status
in the status bar.
Active AIS alarms list
The active alarm list shows the status of each local alarm. This list
can be accessed from the chart application by going to Menu >
AIS Options > AIS Unit Set-up > View AIS Unit Log, or from the
radar applications by going to Menu > Track Targets > AIS Unit
Set-up > View AIS Unit Log.
Acknowledging AIS alarms
In the chart or radar application:
1. Select Ok on the alarm dialog box.
Note: An AIS alarm remains active until it is acknowledged on
your multifunction display.
13.14 Buddy tracking
The Buddy Tracking feature enables you to add AIS-equipped
friends and regular contacts to a “Buddy List” on your multifunction
display. As soon as a vessel on your Buddy List sails into the range
of your AIS unit, the vessel icon changes to indicate this.

How it works
When the AIS Layer is enabled in the chart or radar application, AIS
targets are shown on your display. You can add any AIS target to
a “Buddy List”, each entry consisting of an MMSI number, and an
optional name. Subsequently, whenever Buddy Tracking is enabled
on your multifunction display, and a “Buddy” vessel with an MMSI
number sails into the range of your AIS receiver, an AIS Buddy icon
is displayed. Up to 100 vessels may be added to the Buddy List.
