31Sea 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 installationsare susceptible to local magnetic disturbances that will cause erroneous heading outputs. The autopilot computer can detect and correctdeviations caused by magnets and iron materials around the fl uxgate- if the earths’ magnetic fi eld near the compass isn’t too distorted. Eventhough the compass corrects iron induced errors, don’t expect the correction to solve all ills associated with iron near the compass, placementof 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 somesmooth water where you can drive in circles without running into anything.1. Turn System On. Autopilot will be in Standby [STBY Mode]Step A. Pressand ReleaseDeckmount Switchto turn autopilot on.Deckmount willbegin to fl ashStep B.[STBY] LEDwill blink for30 seconds.2. Press, release and light up the [Setup] LED on the Handheld, and enter code 47 on the handheld.Step C. When the Autopilot isdone loading the [STBY] LEDwill light solid.Step B.

Press and release[Setup] button once toilluminate [SETUP] LED.3. To start Compass calibration.Step B. Press andHOLD the[Select Load]GPS button.Step D. Release [SelectLoad] buttonStep E. The [UP]arrow LED will lightsolid. (Continue driv-ing in a straight line.)Step F. Continue to drivein a straight line and watchfor the [UP ARROW] LEDto start blinking.Step H. Turn at a rate that makes a full 360degree turn in about 30 seconds. You willneed 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 andthe system will completely power down.Your compass is now calibrated.Step G. Whenthe up arrowstarts blinking,begin turning theboat to starboard.Step A. Start driving theboat in a straight line. Step C. While holding downthe [Select Load] button. Pressand Release the [Deckmount]button once quickly.• If Up and Down Arrows both blink continuously, compass calibration has failed - you must turn the system off by holdingthe Deckmount On/Off button down in order to try calibration again. Make sure the compass is mounted at least 24” awayfrom any magnetic material, i.e. radios, speakers etc. Make sure it is orientated in the bracket correctly.
