3.1.2 C34 Automatic compass deviation compensation (Auto DEV)
(Auto DEV) is performed by driving the boat in a circle up to 1¼ turn,
so that the magnetic deviation can be measured, and by that
compensated.
Set the mast in zero position.
Select calibration code C34 (Auto DEV).
Drive the boat in a circle for 1 1/4 turn in calm water. When you
start the circle manoeuvre, press SET.
The un-deviated compass course will be shown in the display as
you turn. Complete the circle up to 1 ¼ turn.
When the manoeuvre is ready, press SET to store the deviation
value.
If the deviation is corrected (Auto DEV) will be displayed.
If the deviation is not corrected, an error message will be
displayed.
Note: You will get the best result in calm water with a smooth turn
on the steering wheel independently of how the circle is
performed. When activated, you can stop the automatic compass
deviation at any time with a LONG press on SET.

3.2.1 C34 Adjust the Roll and Trim
In order to adjust mounting angle and set the Zero position of the
mast. Follow this procedure:
1. Make sure the boat is at 0° Roll and Trim
2. Make sure the mast is at it zero rotation position
3. Press SET for more than 2 sec.
4. Goto C30 with PAGE
5. Goto C34 with PLUS
6. Press SET.
7. Press SET again within 5 sec.
Now the Mounting angle and the zero position has been detected
Repeat step 5 and 6 above (press SET followed by SET) to fine
tune (set to zero) the Roll and Trim angles.
