Right click the [TUNE] button on the Instan-
tAccess bar
™
then select [Tune Initialize] to
start initialization. "TUNE IN" appears
during the initialization.
3.2 How to Align the 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 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-
ing adjustment will compensate for this error.
