5.5.5 GROUNDING ALARM (GUARDIAN TECHNOLOGY)
The chart plotter is provided with a function that, by querying the map's
data, verifies potential danger to navigation due to shallow water, land, rocks,
obstructions and shoreline constructions. The maps are scanned periodically (every
10 seconds). When the Grounding Alarm is active, the chart plotter scans an area in
front of the boat. This area is identified by a triangle drawn in front of the boat icon
whose direction is determined by the current boat heading. The length of the triangle
is user selectable and its angle is 30 degrees. If any of the above objects are found, the
chartplotter notifies the danger on a dedicated warning message box in the Grounding
Alarm Report page (see Par. 5.5.8). The Grounding Alarm is switched Off by default
after a Master Reset. Once the Grounding Alarm has been activated, a warning message
is shown.

The Grounding Alarm function only operates with the new C-CARDs. It also affects the speed
of the redraw of the screen. If this function is not used it maybe disabled.
5.5.6 GROUNDING ALARM RANGE
Allows setting the length of the sector to be detected among 0.25, 0.5, 1.0

scanned area, a tick marker is printed on the relative box in the Grounding Alarm
Report page (see Par. 5.5.9) to identify which dangerous objects have been currently
detected.
