HS80/MX575C alignment
The top of the HS80/MX575C 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 HS80/MX575C alignment within the HS80/
MX575C software configuration. Alternatively, you can physically adjust the heading of
the HS80/MX575C so that it renders the correct heading measurement; however, adding a
software offset is an easier process.
Mounting options
The HS80/MX575C allows for two different mounting options: flush mount and pole mount.
•
Flush mount - The bottom of the HS80/MX575C contains eight M8-1.25 holes for flush
mounting the unit to a flat surface (see Figure 2-6). The eight holes comprise two sets of four
holes. The inner four holes are in the same location as the HS70, allowing you to use the HS80/
MX575C as a drop-in replacement. The outer four holes provide a wider mounting option.
•
Pole mount - The bottom of the HS80/MX575C contains a mounting hole (1” thread, 0.9”
depth) for easy pole mounting. Hand tighten until snug (do not over tighten). The set screws
on the long sides of the base (see middle drawing in Figure 2-6) allow you to secure the HS80/
MX575C in place (3/16” Allen wrench not included).
