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 Aids to NavigationAn AIS aid to navigation (ATON) is any kind of navigational aidthat is transmitted over the AIS radio. ATONs are displayed onthe charts and have identifying information, such as position andtype.There are three main kinds of AIS ATONs. Real ATONsphysically exist and send their identifying and locationinformation from their actual location. Synthetic ATONsphysically exist, and their identifying and location information issent from another location. Virtual ATONs do not actually exist,and their identifying and location information is sent fromanother location.You can view AIS ATONs on the chart when the chartplotter isconnected to a compatible AIS radio. To show AIS ATONs, froma chart, select MENU > Layers > Chart > Navaid > ATONs.You can view more information about an ATON if you select theATON on the chart.Symbol MeaningReal or synthetic ATONReal or synthetic ATON: Topmark NorthReal or synthetic ATON: Topmark SouthReal or synthetic ATON: Topmark EastReal or synthetic ATON: Topmark WestReal or synthetic ATON: Topmark SpecialReal or synthetic ATON: Topmark SafeReal or synthetic ATON: Topmark DangerVirtual ATONVirtual ATON: Topmark NorthVirtual ATON: Topmark SouthVirtual ATON: Topmark EastVirtual ATON: Topmark WestVirtual ATON: Topmark SpecialVirtual ATON: Topmark SafeVirtual ATON: Topmark DangerAIS 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.Navigating to a Distress Signal TransmissionWhen you receive a distress signal transmission, a distresssignal alarm appears.Select Review > Go To to begin navigation to thetransmission.AIS Distress Signal Device Targeting SymbolsSymbol DescriptionAIS distress signal device transmission.
