Autodeviated.
The text [CHK] starts flashing and a pointer will show you the course
where to end. When you have taken the boat through the minimum 360
turn, press KEY again, and 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.

otherwise you are unable to see the difference between local magnetic
variation and alignment error. The Compass may be installed reversed
