5.7 Relative Bearing Alignment
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 mark (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,
up to 360° degrees.
1) Identify a suitable target (for example,
ship or buoy) at a range between 1/8 to
1/4 miles, preferably near the heading
mark. To minimize error, keep echoes in
the outer half of the picture by changing
the range.
2) Display the Installation Setup 2 menu.
