Setting the Safe-Zone Collision Alarm
Before you can set a collision alarm, you must have a
compatible chartplotter connected to an AIS device or radar.
The safe-zone collision alarm is used only with AIS and MARPA.
MARPA functionality works with radar. The safe zone is used for
collision avoidance and can be customized.

A message banner appears and an alarm sounds when a
MARPA-tagged object or 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.

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.

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.
