Indication of the Repeater Compass after putting into operation

During the heating stage of the supplied gyro compass (up to approx. 0,5 h after putting the
compass into operation) there is no indication of the heading at the Repeater Compass.
After the heating stage has ended, the settling phase of the gyro compass starts.
During this settling phase the indicated heading of the Repeater Compass and of the gyro
compass is active. But only when the settling phase has ended (after approx. 3 h) the
heading indication can be used for navigation.

Indications during GPS compass operation

If the Repeater Compass is used with a Raytheon GPS compass the heading indication is
available after the alignment stage (approx. 10 to 15 minutes).
If the connection between the GPS compass and the corresponding satellite is disturbed, no
heading indication is available.
Approx. 10 to 15 minutes after establishing the connection to the satellites the current
heading is indicated again.
