2.12 Erasing the Heading Line, North Marker

The heading line indicates the ship's heading in all presentation modes. It 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 orientation in the north-up, course-up

and true motion modes with ship’s movement.

The north marker appears as a short dashed line. In the head-up and course-up modes the

north marker moves around the bearing scale as the ship’s heading moves.

To temporarily erase the heading line and north marker, press the RADAR DISPLY soft key

followed by the HL OFF soft key. Release the key to redisplay the markers. (If the radar soft

keys are not shown, hit the HIDE/SHOW key to display them.)

Noise, appearing on the displays as random “speckles,” can be reduced as follows:

1. Press the MENU key to open the menu.

2. Press the RADAR DISPLAY SETUP soft key.

3. Select NOISE REJECTION, then press the EDIT soft key.

4. Select OFF, LOW or HIGH as appropriate.

5. Press the ENTER soft key.
