Setting the Safe-Zone Collision Alarm
Before you can set a safe-zone collision alarm, you must have a
compatible chartplotter connected to an AIS device.
The safe-zone collision alarm is used only with AIS. The safe
zone 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 an
AIS-activated vessel enters the safe-zone area around your
boat. The object is also labeled as dangerous on the screen.
When the alarm is off, the message banner and audible
alarm are disabled, but the object is still labeled as
dangerous on the screen.
2
Select Range.
3
Select a distance for the safe-zone radius around your
vessel.
4
Select Time To.
5
Select a time at which the alarm will sound if a target is
determined to intersect the safe zone.
For example, to be notified of a pending intersection 10
minutes before it will likely occur, set Time To to 10, and the
alarm will sound 10 minutes before the vessel intersects the
safe zone.
AIS Distress Signals
Self-contained AIS distress signal devices transmit emergency
position reports when activated. The chartplotter can receive
signals from Search and Rescue Transmitters (SART),
Emergency Position Indicating Radio Beacons (EPIRB), and
other man overboard signals. Distress signal transmissions are
different than standard AIS transmissions, so they appear
differently on the chartplotter. Instead of tracking a distress
signal transmission for collision avoidance, you track a distress
signal transmission to locate and assist a vessel or person.
Navigating to a Distress Signal Transmission
When you receive a distress signal transmission, a distress
signal alarm appears.
Select Review > Go To to begin navigation to the
transmission.

Enabling AIS Transmission Test Alerts
To avoid a large number of test alerts and symbols in crowded
areas such as marinas, you can select to receive or ignore AIS
test messages. To test an AIS emergency device, you must
enable the chartplotter to receive test alerts.

Select an option:
• To receive or ignore Emergency Position Indicating Radio
Beacon (EPRIB) test signals, select AIS-EPIRB Test.

select AIS-MOB Test.
• To receive or ignore Search and Rescue Transponder
(SART) test signals, select AIS-SART Test.
Turning Off AIS Reception
AIS signal reception is turned on by default.
Select Settings > Other Vessels > AIS > Off.
All AIS functionality on all charts and 3D chart views is
