6.11 Heading Line
The heading line indicates your heading in all orientation modes.
This line connects between your position to the outer edge of the
radar display. The line is at zero degrees on the bearing scale in
the head-up mode. The orientation of the line changes in the
north-up mode with the movement of your ship. If it is hard to
identify the echoes on the heading line, you can hide the head-
ing line and range rings for a few seconds. Open the pop-up
menu, then tap [HDG Line Off] to hide the heading line and
range rings. The heading line and the range rings reappear after
approx. 5-6 seconds.
6.12 How to Reduce Radar Interference
Radar interference can occur when your ship is near the radar of another ship that op-
erates on the same frequency band with your radar. The interference shows on the
screen in many bright dots. The dots can be random or in the shape of dotted lines
that run from the center to the edge of the screen. You can identify the interference
from the normal echoes, because the interference does not appear in the same loca-
tion at the next rotation of the antenna.
Turn off the interference rejector when there is no interference to prevent the loss of
weak targets.
To use the interference rejector, open the Layers menu, then turn [Interference Re-
jection] on or off.
