Setting the Safe-Zone Collision Alarm
WARNING
This feature is a tool for situational awareness only and may not prevent groundings or collisions in all
circumstances. It is your obligation to ensure safe operation of your vessel.
CAUTION
The Beeper setting must be turned on to make alarms audible (System Settings, page101). Failure to set
audible alarms could lead to injury or property damage.
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.
Units Settings
Select Settings > Units.
System Units: Sets the unit format for the device. For example, Custom > Depth > Fathoms sets the unit format
for depth to Fathoms.
Variance: Sets the magnetic declination, the angle between magnetic north and true north, for your present
location.
North Reference: Sets the direction references used in calculating heading information. True sets geographic
north as the north reference. Grid sets grid north as the north reference (000º). Magnetic sets the magnetic
north as the north reference.
Position Format: Sets the position format in which a given location reading appears. Do not change this setting
unless you are using a map or chart that specifies a different position format.
Map Datum: Sets the coordinate system on which the map is structured. Do not change this setting unless you
are using a map or chart that specifies a different map datum.
Time: Sets the time format, time zone, and daylight saving time.
