3. HOW TO SET UP THE EQUIPMENT
3-13
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.
2. Turn the vessel’s bow toward a target.
3. Tap the [Home] icon to show the home screen and display mode settings.
4. Tap [Radar] to show the [Radar] menu.
5. Tap [Antenna Heading Align].
6. Key in an offset value (setting range: +179.9° to -180°) that puts the target at the
very top of the screen, then tap the icon.
+: rotate echo in clockwise direction
-: rotate echo in counterclockwise direction
7. Confirm that the target echo is displayed at correct bearing on the screen.
3.5 How to Set Up the Sounder
If you have an internal sounder or BBDS1 or DFF series, set up the sounder as shown
