How to align the antenna heading
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).
You may observe a minor bearing error on the display. This is due to the difficulty in
orienting the radar accurately. The following adjustment will compensate for the error.
