Heading Alignment

1. Turn on the power. Locate a target (buoy, etc.) in the bow direction and display it
on the screen at a close range. The heading alignment is correct if the target in
the bow direction is displayed 12 o'clock on the screen. If it is not, go to step 2.
Buoy
2. Read the skewed degree of the target selected at step 1.
3. Press the [MENU] key.
