To display local time on the screen, set the time difference from the
UTC.
Memory Clear:
Restore the default settings. However, Purpose, Type, View Position and

Heading Adjustment
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
difficulty in achieving accurate initial positioning of the antenna unit. The following
adjustment will compensate for this error.
1. Set ship’s heading toward a suitable target (for example, ship or buoy) at a range
between 0.125 and 0.25 nautical mile.
