System Function Alarm
When an abnormal state of an input signal or a trouble in the processing circuitry occurs, an character or alarm
is generated. When an alarm occurs against any ATA function, ATA (DATA) will appear in the WARNING
display area, but no indication is made in the ATA information display. This status means that there is any
operational trouble in the ATA system. Please, contact the service depot or the manufactures.

Gyro Set Alarm
The North Stabilizing Kit (NSK) in this system receives signals from a gyro. Even if the power is turned off,
the system will follow up the gyro. However, the system stops the follow-up operation when the power of the
master gyro is turned off or when any trouble occurs to the line. When the power of the master gyro is
recovered, the SET GYRO alarm will be generated.
If this alarm occurs, set the gyro.
