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 ap-

pear on the heading line (zero degrees).

In practice, you will probably observe some small bearing error on the display be-

cause of the difficulty in achieving accurate initial positioning of the antenna unit.

The following adjustment will compensate for the error.

1) Select a range between 0.125 and 0.25 nm and set the mode to “head up“.

You can select a range by a pinch action. The range and range ring interval

appear at the bottom left of the screen.

Or tap the radar scale box at the bottom left-hand corner of the screen to dis-

play the slider bar. Drag the circle icon to set the range scale.

2) Turn the vessel’s bow toward a target.

3) Tap the Home icon, then select [Menu] icon, [Radar], and [Antenna Heading

Align] in that order to show the numeric software keyboard.

4) Key in the offset value so that the target is at the very top of the screen (setting

range: +/- 0° to 180°, +: clockwise direction, -: counterclockwise direction),

then tap [Save].

5) Confirm that the target echo is displayed at correct bearing on the screen.
