32 SmartPilot Verado Installation and Commissioning Guide
• the display will show a TOO FAST message if you turn the boat too quickly for the
SmartPilot computer to correct the compass. Apply less helm to turn in a larger
circle
Note:
If necessary, you can quit the correction process by pressing the standby or disp. If you then want
to repeat the deviation correction, return to the SWING COMPASS screen.
5. Continue slowly turning the boat until the controller beeps and displays the DEVIATION
screen. This indicates that the SmartPilot has completed the deviation correction.
Note:
This screen shows the maximum deviation encountered over 360° (not as an east/west value).
If the deviation figure exceeds 15° or the display shows no deviation value, the compass is
being affected by ferrous objects on your boat. You should move the compass to a better
location. Higher deviation figures are acceptable on steel boats.
Aligning the compass heading
Depending upon the orientation of the compass, the heading will require adjusting, if facing
Aft, it could be 180
o out.
1. Once the deviation is displayed, press disp to move to the Heading Alignment page
(ALIGN HDG).
2. Manually steer the boat on a steady course at a speed which enables you to hold that
course.
3. If you have a GPS connected to your SmartPilot:
• increase the boat speed to more than 3 knots
• press
auto
: the SmartPilot will then set the heading to agree with the COG (course
over ground) heading received from the GPS
• as many factors can cause a difference between heading and COG (such as tides and
leeway affecting the boat) you must then fine-tune the heading alignment so it
matches the boat’s steering compass or a known transit bearing
4. Use -1 , +1 , -10 and +10 keys to adjust the displayed heading until it matches boat’s
steering compass or a known transit bearing.
5. Press and hold standby for 2 seconds to exit Seatrial Calibration and save the new com-
pass settings.
