5.4. Forward Looking Alarm Use

The user can define an alarm which will automatically notify the user of potentially hazardous obstacles.
The user can define the area of surveillance for the alarm by depth, minimum range, maximum range, and
field-of-view angle width. The user is notified by both visual and audible notifications. Additionally, the user
can specify the number of hits before the alarm is triggered.

Figure 20. Alarm Volume shown in red

Alarm Configuration

The user definable alarm is configured under the System Menu's 3D Sonar Display option. When configuring
the alarm, the user can define the volume of water within which targets will trigger the alarm. The trigger
area is defined to be the volume of water bounded by 4 thresholds: Max Depth, Min Range, Max Range
and Field-of-View (FOV) angle.

Figure 21. Alarm configuration settings

The FOV setting specifies the sector width of the alarm trigger volume in degrees. For example 60° means
that only targets within 30° to either side of the bow will be able to trigger the alarm. The Max Depth setting
specifies the maximum depth of the alarm trigger volume. The Min Range setting specifies the minimum
range extent of the alarm trigger volume. The Max Range setting specifies the maximum range extent of
