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).
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.
1. Set your radar with 0.125 and 0.25 nm range and the head up mode.
You can select a range by using the pinch action. The range appears at the bottom
right of the screen. Range may also be selected using the slide bar displayed on
the right-hand side of the radar display area. Drag the bar up to zoom in, or down
to zoom out.
