How to Align the Heading

Therefore, a small but conspicuous target dead ahead visually must 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-

1. Select a stationary target echo at a range between 0.125 and 0.25 NM, preferably
near the heading line.
2. Operate the EBL control to bisect the target echo.
