„About track numbers
zTrack numbers may not be created in proper places,
depending on the source to be recorded from, such as
signals with noise.
zThe track numbers on the playback side may not
match the track numbers recorded on the MiniDisc.
zWhen recording, if a programmed playback is per-
formed by the source or playback is performed by
selecting tracks manually, the MiniDisc track numbers
may not be the same as on the source.
zTrack numbers may not be created properly, depend-
ing on the connected stereo system.
„About sampling rate converter
This portable MD incorporates a sampling rate converter
meaning it can record from digital radios or DAT tape
recorders.
„Note for digital recording
You cannot copy a MiniDisc that you recorded from digital
inputs to another MiniDisc or DAT. It is prevented by the
SCMS (Serial Copy Management System). Recording
from analogue inputs is not affected.
1. Track numbers are created automatically during re-
cording via the analogue connection when a silence
of 1 second or more is detected (Auto marker func-
tion). A series of tracks can be recorded as one by
disabling the auto marker function see page 18.
2. When recording from a CD or a MiniDisc using the
digital connection, track numbers will be created at
the same points as on the CD or MiniDisc (Synchro
marker function).
