Symbol DescriptionTarget is activated. The target appears larger on the chart. Agreen line attached to the target indicates the heading of thetarget. The MMSI, speed, and direction of the vessel appearbeneath the target, if the details setting has been set toShow. If the AIS transmission from the vessel is lost, amessage banner appears.Target is lost. A green X indicates that the AIS transmissionfrom the vessel is lost, and the chartplotter displays amessage banner asking whether the vessel should continueto be tracked. If you discontinue vessel tracking, the losttarget symbol disappears from the chart or the 3D chart view.Dangerous target in range. The target flashes while an alarmsounds and a message banner appears. After the alarm hasbeen acknowledged, a solid red triangle with a red lineattached to it indicates the location and the heading of thetarget. If the safe-zone collision alarm has been set to Off, thetarget flashes, but the audible alarm does not sound and thealarm banner does not appear. If the AIS transmission fromthe vessel is lost, a message banner appears.Dangerous target is lost. A red X indicates that the AIStransmission from the vessel is lost, and the chartplotterdisplays a message banner asking whether the vessel shouldcontinue to be tracked. If you discontinue vessel tracking, thelost dangerous target symbol disappears from the chart or the3D chart view.The location of this symbol indicates the closest point ofapproach to a dangerous target, and the numbers near thesymbol indicate the time to the closest point of approach tothat target.NOTE: Vessels being tracked with the Blue Force Trackingfeature are indicated with a blue-green color regardless of theirstatus.Heading and Projected Course of Activated AISTargetsWhen heading and course over ground information are providedby an activated AIS target, the heading of the target appears ona chart as a solid line attached to the AIS target symbol. Aheading line does not appear on a 3D chart view.The projected course of an activated AIS target appears as adashed line on a chart or a 3D chart view. The length of theprojected course line is based on the value of the projectedheading setting. If an activated AIS target is not transmittingspeed information, or if the vessel is not moving, a projectedcourse line does not appear. Changes in the speed, course overground, or rate of turn information transmitted by the vessel canimpact the calculation of the projected course line.When course over ground, heading, and rate of turn informationare provided by an activated AIS target, the projected course ofthe target is calculated based on the course over ground andthe rate of turn information. The direction in which the target isturning, which is also based on the rate of turn information, isindicated by the direction of the barb at the end of the headingline. The length of the barb does not change.When course over ground and heading information are providedby an activated AIS target, but rate of turn information is notprovided, the projected course of the target is calculated basedon the course over ground information.Showing AIS Vessels on a Chart or 3D Chart ViewBefore you can use AIS, you must connect the chartplotter to anexternal AIS device and receive active transponder signals fromother vessels.You can configure how other vessels appear on a chart or on a3D chart view. The display range configured for one chart orone 3D chart view are applied only to that chart or to that 3Dchart view. The details, projected heading, and trails settingsconfigured for one chart or one 3D chart view are applied to allcharts and to all 3D chart views.1 From a chart or 3D chart view, select Menu > Other Vessels> Display Setup.2 Select an option:• To indicate the distance from your location in which AISvessels appear, select Display Range, and select adistance.• To show details about AIS-activated vessels, selectDetails > Show.• To set the projected heading time for AIS-activatedvessels, select Proj. Heading, and enter the time.• To show the tracks of AIS vessels, select Trails, andselect the length of the track that appears using a trail.Activating a Target for an AIS Vessel1 From a chart or a 3D chart view, select an AIS vessel.2 Select AIS Vessel > Activate Target.Viewing Information about a Targeted AIS VesselYou can view the AIS signal status, MMSI, GPS speed, GPSheading, and other information that is reported about a targetedAIS vessel.1 From a chart or a 3D chart view, select an AIS vessel.2 Select AIS Vessel.Deactivating a Target for an AIS Vessel1 From a chart or a 3D chart view, select an AIS vessel.2 Select AIS Vessel > Deactivate Target.Viewing a List of AIS ThreatsFrom a chart or 3D chart view, select Menu > Other Vessels> AIS List.Setting the Safe-Zone Collision AlarmBefore you can set a safe-zone collision alarm, you must have acompatible chartplotter connected to an AIS device.The safe-zone collision alarm is used only with AIS. The safezone is used for collision avoidance, and can be customized.1 Select Settings > Alarms > AIS > AIS Alarm > On.A message banner appears and an alarm sounds when anAIS-activated vessel enters the safe-zone area around yourboat. The object is also labeled as dangerous on the screen.When the alarm is off, the message banner and audiblealarm are disabled, but the object is still labeled asdangerous on the screen.2 Select Range.3 Select a distance for the safe-zone radius around yourvessel.4 Select Time To.5 Select a time at which the alarm will sound if a target isdetermined to intersect the safe zone.For example, to be notified of a pending intersection 10minutes before it will likely occur, set Time To to 10, and thealarm will sound 10 minutes before the vessel intersects thesafe zone.AIS Distress SignalsSelf-contained AIS distress signal devices transmit emergencyposition reports when activated. The chartplotter can receivesignals from Search and Rescue Transmitters (SART),Emergency Position Indicating Radio Beacons (EPIRB), andother man overboard signals. Distress signal transmissions aredifferent than standard AIS transmissions, so they appeardifferently on the chartplotter. Instead of tracking a distresssignal transmission for collision avoidance, you track a distresssignal transmission to locate and assist a vessel or person.6 Charts and 3D Chart Views
