4.1.6 Calibration (ST6)
Magnetic deviation, caused by the vessel
itself, results in incorrect compass readings.
This magnetic deviation can be corrected
by means of the calibration procedure.
• Press in the default mode to enter
the menu.
• Use the /
the Calibration menu (ST6).
• Press to enter the Calibration
menu.
• Use the /
Auto or Manual.
4.1.6.1 Automatic calibration
The electronic compass has an automatic
calibration procedure. Default 'Auto Cali-
bration' is 'ON'.
The compass sensor will calibrate itself
every time two full circles at a constant
speed have been made within 1 to maxi-
mum 4 minutes per circle.
You can switch this function OFF and use
the manual calibration command.
4.1.6.2 Manual calibration
To calibrate the compass sensor you need
a calm day and a clear area. Start turning
your boat in a large circle at a constant
speed. Then select calibrate in the menu
and press and
er for two seconds. Now the display shows
the heading and 'In process'. The time to
complete the circle (full 360°) should be at
least 1 up to maximum 4 minutes. When
the calibration was successful the display
shows 'Done' and a short beep will be
heard. Circles may be clockwise or coun-
ter clockwise.
If the circle was not in between the time
limits, the old calibration is restored and
you can see on the display if the circle was
too fast or too slow.
