Compass Mounting Considerations
This compass requires a clear, unobstructed view of the sky and horizon in all directions, and installing it near
any structure on the boat will negatively affect performance. You should test the selected location before
permanently installing the compass.
NOTE: The compass may lose heading information when operating below a bridge, under a slip, or near tall
structures. To retain heading information in these situations, the MSC 10 can be configured to use an internal
magnetic compass as a backup to the GPS compass (recommended). To enable this backup, you can calibrate
the device
(Heading Calibration, page
You can mount the compass on a flat surface or attach it to a standard stainless steel, 1 in. OD, 14 threads per
inch, pipe-threaded pole (not included). You can route the cable outside of the pole or through the pole. For best
performance, consider these guidelines when selecting the mounting location:
• The compass must be mounted in a location that has a clear, unobstructed view of the sky in all directions
. Select a location that has no objects higher than five degrees above the device.
• The compass must not be mounted where it is shaded by the superstructure of the boat
antenna, or the mast.
• The compass must not be mounted inside or adjacent to the cabins.
• The compass should not be mounted near the engine or other sources of Electromagnetic Interference (EMI)
.
• If a radar is present, the compass should be mounted above the path of the radar
compass may be mounted below the path of the radar
• The compass should not be mounted directly in the path of the radar
• The compass should not be mounted within 1 m (3 ft.) of a VHF radio antenna
