to the tape drive and to the NonStop system. Use the display to view the state of the 
tape drive, fault symptom codes when applicable, and the menu selections and 
configurations states when the tape drive is in Menu mode.
Messages can be stable or blinking, and two messages can alternate. Operator panel 
displays might be shown twice, abbreviated in quotation marks and with full spelling. 
Abbreviated spellings in the quotations show exact display presentation. The full 
spelling is added to clarify meanings.

symptom code. The code itself is not important for identifying the error type in the field.
