1.30 Markers

1.30.1 Heading marker and heading line
The heading marker and the heading line indicate 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, and in
the north-up and true motion modes it changes with ship's movement. The heading marker
appears as a small circle on the bearing scale to indicate the heading when the display is
off-centered or is in north-up or TM mode.
Temporarily erasing heading line
To temporarily extinguish the heading line to look at targets existing dead ahead of own
ship, press the [HL OFF] key. The heading line reappears when the key is released.
1.30.2 North marker
The north marker appears as a short dashed line. In the head-up mode, the north marker
moves around the bearing scale in accordance with the gyrocompass signal.
1.30.3 Stern marker
The stern marker (a dot-and-dash line) appears opposite to the heading line. This marker
can be displayed provided that STERN MK ON is selected on the RADAR 2 menu.
