Confirm Heading Sensor Operation
It is important to confirm that the heading sensor is installed correctly
by reviewing the heading digital readout.
NOTE: This procedure should be performed at slow
speeds, in calm, open water, in a large area that is far
from shallow water, boats, or other obstacles.
1. From the Home screen, select the GPS tool
2. Under GPS 1, select Satellites.
3. Confirm the Heading (Hdg) and Course Over Ground (COG) data
boxes are displayed.
NOTE: See your operations manual for information about
selecting data boxes.
4. Navigate the boat in a straight line, in calm, open water at
4.5 mph. Compare the Heading (Hdg) digital readout on the
screen with the Course Over Ground (COG) digital readout. The
readouts should be within approximately 5˚ of each other.
To adjust the zero point of the heading sensor, open your
Network settings and adjust the Heading Adjustment setting as
needed. See your control head operations manual for more
information.
If the procedure failed: If there is a difference of more than 5˚
between the Heading (Hdg) and Course Over Ground (COG)
digital readouts, the Sensor might be installed in a location with
too much magnetic interference. Check the installation
location and possible magnetic disturbances in the area.
