2.8
Heading Line and North Marker
2.8.1
Heading line
The heading line shows the own ship’s heading. In the HEAD-UP mode, the heading
line appears right above own ship (0°). In the NORTH-UP and the COURSE-UP modes,
the heading line moves according to own ship's movement.
2.8.2
How to adjust the heading line
A small but conspicuous target dead ahead may appear on the heading line (zero
degrees) even if you installed the antenna unit facing straight ahead in the direction of
the bow. It is because of the difficulty in achieving accurate initial positioning of the
antenna unit in practice. The following adjustment will rectify this error.
1. Select a stationary target echo at a range between 0.125 and 0.25 NM, preferably
near the heading line.
Note:
Refer to section 1.1 for setting the display range. Refer to section 2.2 for how to
change the display mode.
