Collision alarm
You can set up a collision alarm zone in front of your vessel to alert
you to charted objects above a specied depth, or below a specied
height.
If the Collision Alarm is set to ON, an alarm is triggered when charted
objects appear in the zone’s vicinity. If an object exits the collision
alarm zone and then re-enters it, a subsequent alarm is raised.
You can specify the size of the collision alarm zone, which consists
of 2 sectors:
• the range in front of your vessel, which can be adjusted between
0.05 and 2 nautical miles.
• the bearing from your vessel (width of the zone), which can be
adjusted between 0 and 90.
The collision alarm zone maintains its relative position to the vessel
as its position and heading changes.
The following charted objects trigger an alarm when they enter the
collision alarm zone:
• Land:
– Land.

– Offshore structures.
