System Function Alarm (TT Data) 
 
When an abnormal state of an input signal or Target Tracking unit  may  have  a  trouble,  alarm  is  generated. 
When an alarm occurs against any Target Tracking function,    TT (Data)    will appear in the alarm indication 
(Software button  վ  located at the operation/message area in Section 2.3.9), but no indication is made in the 
Tracked  Target information  display  (panel display area  in  Section 2.3.8).  This  status  means  that  there is  any 
operational trouble in the Target Tracking unit. Please, contact the service depot or the manufactures.

Gyro Set Alarm 
 
The GYRO I/F 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.
