3 If the rotor is not completely stopped when the POWER button is
pressed, a rotor break function will be activated to stop the rotor.
Active rotor break is indicated with flashing display.
4 When the turning stops, the Sensitive element starts rising
horizontally and the compass rotates 360° clockwise. The display
shows decreasing bearing as the compass is turning.
5
When the compass has rotated 360°, start bearing is indicated with
flashing text in the display. The start bearing will be the same as
active bearing when the compass was turned OFF.
6 The indicated start bearing is accepted by pressing the ACK/ENT
button, or increased/decreased by using the ARROW buttons and
then pressing the ACK/ENT button. If no action is taken within 3
minutes, the start-up process will continue with the indicated start
bearing.
The bearing indication stops flashing when the start bearing is
accepted, while the lamp and the S.S.G. (mode) continues to flash.
7 The rotor will now start rotating, and reaches full speed after
maximum 30 minutes.
8
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.
The lamp near the GYRO button changes from flashing to steady
light, but the S.S.G. (mode) continues to flash for 3 hours.
The Gyro 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.

It is very important that the rotor break is activated to stop the rotor
rotation to prevent any possible damage by ship's movement!
