Heading alignment

You have mounted the antenna unit facing straight ahead in the direction of the bow.
Therefore, a small but conspicuous target dead ahead visually should appear on the
heading line (zero degrees).
In practice, you will probably observe some small bearing error on the display because
of the difficulty in achieving accurate initial positioning of the antenna unit. The follow-
ing adjustment will compensate for the error.
