Markers

2.25.1

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.
2.25.2

Stern marker

The stern marker, which is a dotted 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 menu then select [5 MAP•MARK] and [1 MARK SETTING].
2. Select [6 STERN MARK] (B type) or [5 STERN MARK] (IMO and A types).
3. Select [ON] or [OFF] as appropriate.
2.25.3

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 compass signal.
2.25.4

Own ship marker

The own ship marker is displayed at your ship's position. It can be turned on or off and
its configuration selected from the [MARK SETTING] menu. Two configurations are
available: minimized marker and scaled marker. The scaled marker is scaled accord-
ing to the length and beam of the vessel. If the beam width or length of the marker (set
at installation) gets smaller than 3 mm, the marker is replaced with the minimized
marker. Ship's dimensions should be entered at installation to use the scaled marker.
Minimized marker
1. Open the menu then select [5 MAP•MARK] and [1 MARK SETTING].
2. Select [4 OWN SHIP MARK] (B type) or [3 OWN SHIP MARK] (IMO and A types).
3. Select [MIN] or [SCALED] as appropriate.
MIN: Show the minimized own ship marker.
SCALED: Show the scaled own ship marker.
