The short line on the bearing scale is the north marker.
Course-up (CU)
The radar picture is stabilized and displayed with the currently selected course at
the top of the screen. As you change heading, the ship's heading marker moves.
If you select a new course, the picture resets to display the new course at the
top of the display.
