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.
1. Set your radar with 0.125 and 0.25 NM range and the head up mode.
The range scale can be selected two ways, as shown below. The slider bar can
be shown or hidden with [Show Scale Slider] in the [Settings] - [Radar] menu.
