Notes on the index
•Index marks are recorded during recording,
you cannot mark an index after recording.
•Index signals will be recorded both on the
tape and on cassette memory. If you use
cassettes without cassette memory or the
cassette memory is full, the signals will be
recorded only on the tape.
•When you record over the recorded tape and
mark an index on the tape, we recommend
that you clear all data in the cassette memory
before marking an index.
