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.
