if successful, the text [CHK Atd] will appear again, otherwise, ERR 17 or ERR 19 will
appear, i.e. the difference between the last Autodeviation and this Autocheck is to big
to be accepted. Make a new Autocheck, and if you still get ERR 19, make a new
Autodeviation since the last one was probably disturbed.
When the Autocheck is OK, the Compass will store the average result from both
Autodev and Autocheck.

If you by any reason prefer to reset the deviation created by the
Autodeviation function, press SET when text [CLR Atd] is
displayed, you are now asked to confirm the flashing text YES

C36 Adjust the Compass alignment
This function is used when the Compass is giving a constant
course error, i.e. it is not mounted exactly aligned as the boat
(there is no need to mount the transducer at the boats
centreline). Make sure that the local magnetic variation is
entered before you make the alignment adjustment, otherwise
you are unable to see the difference between local magnetic variation and alignment
error. The Compass may be installed reversed 180

C37 Off course alarm
This function is used to set a course alarm that will be activated
when the boats average course is more than set value. The text
[OCA OFF] is displayed. Press SET to enter the maximum
allowed course error, then press SET again.
This function is filtered for 30s to avoid false alarms such as
when sailing in heavy sea. Set to 00 will turn alarm OFF.

Adjustment of the roll offset. Mount the roll transducer according
to the instructions. Adjust the offset so the roll is displaying 00°
when the boat is horizontal. By entering a minus sign [-] in front
of the value the roll will be decreased by the value. When the offset is without a minus
sign, it will be added. When a roll transducer is connected, both wind speed and wind
angle will be compensated for the roll and thus increasing the accuracy.
The roll sensor is not available at the time for this manual.
