Sea Trial Setup: Steps 10-15 will need to be performed on open water, free of obstacles.
10. Calibrate your compass. The autopilot compass is made with a fl uxgate. Like all compass installations, fl uxgate installations
are susceptible to local magnetic disturbances that will cause erroneous heading outputs. The autopilot computer can detect and correct
deviations caused by magnets and iron materials around the fl uxgate- if the earths’ magnetic fi eld near the compass isn’t too distorted. Even
though the compass corrects iron induced errors, don’t expect the correction to solve all ills associated with iron near the compass, placement
of the compass in an iron free area is critical. You should only calibrate the compass on calm water. Stay away from large steel structures.
Calibration will not work right if you try to do calibration with your boat on the trailer because the trailer is made with iron. Find some
smooth water where you can drive in circles without running into anything.

degree turn in about 30 seconds. You will
need to make at least 3 or more full turns.
Keep turning until the [UP ARROW] &
[DOWN ARROW] LED’s both light up.
They will stay lit for about 5 seconds and
the system will completely power down.
Your compass is now calibrated.

button once quickly.
• If Up and Down Arrows both blink continuously, compass calibration has failed - you must turn the system off by holding
the Deckmount On/Off button down in order to try calibration again. Make sure the compass is mounted at least 24” away
from any magnetic material, i.e. radios, speakers etc. Make sure it is orientated in the bracket correctly.
