ALARM MESSAGES AND CORRECTIVE ACTIONS
Master compass running stop function
When any abnormal condition or failure (as E-3/E-A is provided or true
heading is unstable) occurs in the Master compass, turn the "Master
compass power switch" S1 in the control unit to OFF. It is now possible to
stop the Master compass from running and change the output of true
heading information to a connected external heading sensor. This will
minimize the loss of heading signal.
When switch S1 is set to OFF, Gyrocompass heading is unavailable.
