, or turn the
rotary control
clockwise,
to select
SWING COMPASS ON
. (On ST8001 & ST8002 systems, you must

4. Start turning the boat in slow circles (with the boat’s speed below 2 knots).
You will need to complete at least two circles, taking at least 2 minutes to
complete each 360°:
• 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

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.
