Aligning heading
(Adjustment sector:0~359.90)
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 error on the display because of the dif-
ficulty in achieving accurate initial position-
ing of the antenna unit. The following
adjustment will compensate for this error.
1. Identify a suitable target (for example, ship
or buoy) at a range between 0.125 to 0.25
nautical miles, preferably near the head-
ing mark. To lessen error, keep echoes in
the outer half of the picture by changing
the range. Also, be sure the zoom and off
center functions are off.
2. Select “9. Heading Alignment” on the in-
stallation setup menu and press the [ACQ/
ENTER] key. The following message ap-
pears on the display.
[ Heading alignment ]
Set EBL1 to center of target
dead ahead and press ENTER.
