1. Switch the course indication on the gyro operator unit to Uncorrected Heading , see
related documentation.
2. Loosen the 3 screws ( Fig. 9 /1) slightly.
3. Check the sense of rotation.
a) Turn the magnetic sonde ( Fig. 9 /2) slowly towards increasing angular degree value
on the magnetic compass card.
Note
The display of the connected system or equipment must show the increasing
angular degree value as well.
b) If the sense of rotation is not correct, interchange the phases S1 and S3 of magnetic
sonde, see chapter 7.3.4 .
4. Turn the magnetic sonde slowly until the course indication of the connected system or
equipment matches the course indication of the magnetic compass.
Note
Repeat the procedure 3 to 4 times so the highest accuracy is achieved.
5. Deflect the magnetic compass, e.g with an iron key and check the course.
