Beacon
A prominent, specially constructed object
forming a conspicuous vertical mark as a fixed

Chart Boundaries
Enables/Disables the displaying of the Chart
Boundaries. Selecting Auto instead, if we are in
background charts only the first charts level
contained in the C-CARD are displayed, if we
are in a charts level contained in the C-CARD
the next four charts level are displayed. The
default setting is On.
Chart Datum
Sets the datum that the electronic chart is set
to. This value should be the same as the paper
chart that is being used. In some instances, it
may be beneficial to set this value to WGS 84
so that two charts of different original datum
can be shown together on the
CND
.
WGS 1984 is the default Chart Datum.
