COMPASS

The GPS Chart Plotter computes compass direction from the constellation of GPS
satellites. For the GPS Chart Plotter to compute direction the vessel must be moving
through the water unless connected to an optional Flux Gate Compass sensor. The
Compass menu allows the GPS Chart Plotter to customize the following selections:
Bearings : Selects between True and Magnetic. When Magnetic bearings is enabled, the GPS Chart Plotter applies
the selected Magnetic Variation (Auto or Manual, see next paragraph) to compute magnetic bearing.
Variation : Allows the user to select Auto or Manual. When Auto mode is selected the GPS Chart Plotter computes
the offset by the current GPS fixed location. Manual mode allows the user to enter in a MagneticVariation
that is applied in the True conversion.
Calibration : Allows a user to enter in the offset for areas that the vessel may cruise instead of entering in a manual offset
for one location. This offset is useful for cruising vessels or vessels that travel internationally often.

ALARMS

The Alarms menu is used to select and setup audible and visual Alarms. Available alarms
are Arrival, XTE, Depth, Anchor and Grounding Alarm.
Arrival Alarm
XTE Alarm
Depth Alarm
Anchor Alarm
Audible Alarm
Grounding Alarm
Grounding Alarm Range : Allows setting the distance of the grounding alarm zone (the length of the sector to be
Grounding Alarm Report: Allows displaying a report of the dangerous objects currently detected.
The Grounding Alarm function is available only if a NT
screen redraw speed so we suggest to disable it when not used.
When any of the objects checked are found for the first time, the GPS Chart Plotter shows a pop
up window to alert the user of the possible danger. The name of each new dangerous object found
is reported in the warning window. In the Grounding Alarm Report page the relative item has a tick
marker next to it, to identify the dangerous object currently detected. If in the next search cycle the
same objects are found again, the alarm window will not be shown. Instead, if in the next searches
the objects found before are no longer detected, their relevant item in the Grounding Alarm Report
page is cleared (note that in this case, if the same object type is found again later, the Alarm will
be shown). The GPS Chart Plotter shows an icon on the charts that identifies when a Grounding
Alarm is detected.
