RED : Undo (or Redo) has been carried out.

(off) : You cannot use the undo function (such as when the previous operation cannot be undone (etc.)).

See page 24 for details about using the undo function with the auto punch-in/out function.

Note

Do to the limitations of this system, if the blank space on the disc becomes too small it may not be possible to use the undo function even if it is set to “on”. In this case, the indicator on the UNDO key will be off. Be sure to check whether this indicator is on or off before performing an edit operations.

Recordable track number setting (Rec)

This sets the number of tracks to be used on the disc. The number of tracks selected is effective the next time a song is recorded. During playback, the number of tracks is selected automatically according to the source disc.

The selectable tracks also differ depending on the type of disc you use (MD DATA or music MD).

Rec Mode	Usable	Recording	Usable
	tracks	time	Discs
4	1~4	37 min.	MD DATA
2	1, 2	74 min.	MD DATA,
			Music MD
1	1	148 min.	MD DATA,
			Music MD

Note

The Rec Mode automatically switches to 2 track for music MDs (even if it was previously set to the 4 track mode). After recording on a music MD, be sure to reset the Rec Mode to 4 track when you want to make a 4 track recording using a MD DATA disc.
