The rotor will now start rotating, and reaches full speed after

When the rotor has reached full speed, the compass starts the north
seeking function. The display will now change to show the compass'
actual heading, and from now on bearing output will be available.

light, but the S.S.G. (mode) continues to flash for 3 hours.
The GC80/85 will be settled within 3 hours when started with a deviation
angle less than 5°. With a larger deviation angle, the compass will be
settled within 4 hours.
