NMEA 2000 or Proprietary, Tachometer, or GPS, configure the high RPM limit. • On a power boat with the speed source set to GPS, configure the maximum speed. 4 Calibrate the compass (Calibrating the Compass, page 2). 5 Perform the Autotune procedure (Performing the Autotune Procedure, page 2). 6 Set north (Setting North, page 2) if GPS-heading information is available, or set the fine heading adjustment (Setting the Fine Heading Adjustment, page 2) if GPSheading information is not available. Calibrating the Compass 1 Select an option: • If you are performing this procedure as part of the Sea Trial Wizard, select Begin. • If you are performing this procedure outside of the Sea Trial Wizard on a helm control, from the heading screen, select Menu > Setup > Dealer Autopilot Setup > Compass Setup > Calibrate Compass > Begin. • If you are performing this procedure outside of the Sea Trial Wizard on a chartplotter, select Settings > My Vessel > Autopilot Installation Setup > Compass Setup > Compass Cal. > Begin. 2 Follow the directions until calibration is complete, taking care to keep the boat as steady and flat as possible. The boat should not list during calibration. 3 Select an option: • If the calibration completes successfully on a helm control, select Done. • If the calibration completes successfully, on a chartplotter select OK. • If the calibration is not successful, select Retry and repeat steps 1 through 3. When the calibration is complete, a value is shown. A value of 100 indicates the CCU was installed in a perfect magnetic environment and calibrated correctly. If this value is low, you might need to relocate the CCU and calibrate the compass again. Performing the Autotune Procedure Before you can begin this procedure, you must have a large stretch of open water available. 1 Adjust the throttle so the boat travels at a typical cruising speed (below planing speed) that provides responsive steering. 2 Select an option: • If you are performing this procedure as part of the Sea Trial Wizard, select Begin. • If you are performing this procedure outside of the Sea Trial Wizard on a helm control, from the heading screen, select Menu > Setup > Dealer Autopilot Setup > Autopilot Tuning > Autotune > Begin. • If you are performing this procedure outside of the Sea Trial Wizard on a chartplotter, select Settings > My Vessel > Autopilot Installation Setup > Autopilot Tuning > Autotune > Begin. The boat performs various zigzag motions while the Autotune is in progress. 3 After the procedure is finished, follow the on-screen instructions. 4 Select an option: • If the Autotune procedure is not successful, but you have not reached maximum cruising speed, increase the speed and repeat steps 1 through 3 until the Autotune procedure completes successfully. • If the Autotune procedure is not successful, and you have reached maximum cruising speed, reduce your speed to the initial Autotune speed and select Alternate Autotune to begin an alternate procedure. When the Autotune procedure is complete, gain values are displayed. You can use these values to determine the quality of the Autotune procedure. Autotune Gain Values After the Autotune procedure is complete, you can review the gain values provided on the helm control. You can record these numbers for reference if you want to run the autotune procedure at a later time or if you want to manually adjust the gain settings (not recommended) (Adjusting the Autopilot Gain Settings, page 3). Gain: Sets how tightly the autopilot holds the heading and how aggressively it makes turns. Counter Gain: Sets how aggressively the autopilot adjusts any over-steering after making a turn. Setting North Before you can begin this procedure, you must have a large stretch of open water available. This procedure appears if the autopilot is connected to an optional GPS device, and the device has acquired a GPS position. During this procedure, the autopilot aligns the compass heading with the Course over Ground (COG) information from the GPS device. If you do not have a GPS device connected, you are prompted to set the fine heading adjustment instead (Setting the Fine Heading Adjustment, page 2). 1 Drive your boat at cruising speed in a straight line. 2 Select an option: • If you are performing this procedure as part of the Sea Trial Wizard, select Begin. • If you are performing this procedure outside of the Sea Trial Wizard on a helm control, from the heading screen, select Menu > Setup > Dealer Autopilot Setup > Compass Setup > Set North > Begin. • If you are performing this procedure outside of the Sea Trial Wizard on a chartplotter, select Settings > My Vessel > Autopilot Installation Setup > Compass Setup > Set North > Begin. 3 Continue to drive the boat at cruising speed in a straight line and follow the on-screen instructions. 4 Select an option: • If the calibration completes successfully, select Done. • If the calibration is not successful, repeat steps 1 through 3. Setting the Fine Heading Adjustment This procedure appears only if you do not have an optional GPS device connected to the autopilot. If the autopilot is connected to a GPS device that has acquired a GPS position, you are prompted to set north instead (Setting North, page 2). 2 Configuring the Autopilot
