Message Meaning
Edit Entry Full In the internal memory for cut information, there is a limit on the
number of files that can be stored. "Edit Entry Full" indicates that
this is full, and that no more files can be created. For editing on
the RP port, temporary files are created internally, and therefore
in this state editing is not possible.
Solution
Hold down the SHIFT key on the MAVE-F555, then press the DEL
FILE key for at least two seconds, to display the message
"FileInitial?" on the screen. If you now press the EXECUTE/REC
key, all of the cut information in the MAV-555 is cleared, making
possible further editing, file creation, and so on. However, since
the information is all cleared, you cannot carry out a cut jump, or
UNDO/REDO operation.
Material Entry Full The material entries on the hard disk of the MAV-555 are full, and
it is not possible to create files.
Solution
Delete unwanted files.
