V102 Alignment
The top of the V102 enclosure incorporates sight design features to help you
align the enclosure with respect to an important feature on your vessel.
To use the sights, center the small post on the opposite side of the enclosure
from you, within the channel made in the medallion located in the center of
the enclosure top as shown in Figure 2-4 and Figure 2-5. Alignment accuracy
when looking through the long site (Figure 2-4) is approxi/- 1°, while
alignment through the short site (Figure 2-5) is approxi/- 2.5°.

If you have another accurate source of heading data on your vessel, such as
a gyrocompass, you may use its data to correct for a bias in V102 alignment
within the V102 software configuration. Alternatively, you can physically
adjust the heading of the V102 so that it renders the correct heading
measurement; however, adding a software offset is an easier process.
