You can select the motion of your ship on the chart and the azimuth of your ship relative to the chart

using the display panel buttons or the menu. Note that the selectable mode differs depending on the

chart type, either S-57/C-MAP Ed.2/C-MAP Ed.3/ARCS.

S-57/C-MAP Ed.2/C-MAP Ed.3 Chart:

(1) Explanation of each mode:

For selectable modes, see the above explanation. For example, on the S-57/C-MAP chart, you cannot

use the combination of [True] or [Free] mode and [Course Up] and [WPT Up] mode. Also, on the ARCS

chart, you cannot select Azimuth mode.

1) Motion mode (True/Relative/Free):

Land and other fixed objects are fixed on the display and only own ship moves on the display.

When own ship reaches the predetermined limit, the chart is automatically shifted so that

own ship always remains on the screen.

You can freely rotate the chart on the display regardless of the own ship's direction of travel.
