Raymarine C90w, C140w manual Buddy tracking, Acknowledging AIS alarms

10.11 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 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 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 data bar icon.

Active AIS alarms list

The active alarm list shows the status of each local alarm. This list can either be accessed via the Menu > AIS Layer Setup Menu, or from the Menu > Alarms Setup Menu.

Note: When local AIS alarms are acknowledged, the target is shown as dangerous (flashing, with a red outline), and the active alarm status icon is displayed until the target is no longer dangerous.

10.12 Buddy tracking

You can configure your display to notify you when an AIS-equipped friend or “buddy” comes within range of your vessel.

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 receiver, 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 mutlifunction 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.
