Heading line

The heading line indicates the ship's heading in all presentation modes. The heading
line is a line from the own ship position to the outer edge of the radar display area and
appears at zero degrees on the bearing scale in head-up mode. It changes its orien-
tation in the north-up and true motion modes according to orientation.
Temporarily erasing the heading line
To temporarily extinguish the heading line (and anything but radar echoes within the
display area) to look at targets existing dead ahead of own ship, push the HL OFF key
on the Control Unit, or click the [HL OFF] button on the InstantAccess bar. Release
the respective control to redisplay the heading line, etc.
2.22.2

Stern marker

The stern marker, which is a dot-and-dash line, appears opposite to the heading line
and marks your ship's stern. To display or erase this marker, do the following:
1. Open the main menu.
2. Select [5 MAP MARK] and [1 MARK SETTING].
3. Select [6 STERN MARK] (B type) or [5 STERN MARK] (IMO and A types).
