format mode before the end of the previously formatted section by
"punching-in". The XT20 begins "time-stamping" from the last valid
time-stamp it reads from tape. This ensures continuous time-stamping
when a tape plays from beginning to end.
To extend the format on a partially formatted tape:
Use [FAST FWD], [REWIND] and/or [PLAY] to locate to the
section of tape just before where formatting was discontinued (before
"noFo" shows in the display).
Press [FORMAT].
The FORMAT icon lights.
Press [PLAY] to engage playback.
When the LOCKED icon appears in the display, hold [PLAY]
and press [RECORD].
The EXT icon lights. The XT20 reads the time reference from tape from
the formatted portion and begins formatting starting from that time
onward.
Exception: If the tape is already formatted but is in the leader or data
sections of the tape (i.e., prior to time 0:00:00.00), entering format mode
will automatically rewind the tape to the beginning and start
reformatting. While rewinding, the TIME counter will read "FO"
(which means "format over") and the [REWIND] LED will flash. This
indication is telling you that the XT20 must format over from the lead
(beginning) portion of the tape.
16/20 Bit: Whichever word-length format (16- or 20-bit) you choose for
the beginning of the tape is the type that must be used for the entire
tape. A tape cannot be 16-bit for one section and 20-bit on another. If
you want to change the word length, you must reformat the entire tape,
erasing all existing audio on the tape as you do so.

If necessary, you can still record on a tape which has had its write-
protect tab removed or damaged. The write-protect tab (located on the
cassette spine) can be removed when you want to protect the
information on an important tape from accidental erasure. The XT20
scans for the presence of a write-protect tab when a tape is inserted. If
no tab exists, recording is prevented. You can, however, tell the XT20 to
ignore the absence of a write-protect tab, and permit recording to take
place anyway.
To override the Write Protect function:
