Plotter Mode

Plotter Mode enables you to zoom into a smaller area, even when no chart data
is available for that scale. This allows you use the chartplotter functions at large
scales even when a chart card is not installed.

Chart Orientation

The chart orientation is normally North Up, but can be changed to Course Up or
Head Up if heading data is available. The orientation modes give the following
displays:
• North Up: The chart is displayed with north upwards. As you change
heading, the ship's heading marker moves. This is the default mode, and is
the only mode available if there is no heading data.
• Course Up: The chart is stabilised and displayed with the currently selected
course upwards. If you select a new course, the picture rotates to display the
new course upwards.
The reference used for the Course Up depends on the information available.
The first available in the following is used:
1. A locked heading over a SeaTalk connection
2. The heading at the time Course Up was selected
To update the Course Up reference whilst Course Up is the current mode, re-
select Course Up from the set up menu.
• Head Up: The chart is displayed with the vessel's current heading upwards.
As the heading changes the chart will rotate.
