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] notification will be issued.
When this notification is issued, set the true bearing value of the gyro. For the details, refer to "5.4.13
