Helpful tip when attaching a label
When attaching a label to an MiniDisc cartridge, be sure to

MiniDisc may jam inside the unit and it may not be pos-
sible to remove it.
●If the label peels off or partially lifts
away, replace it with a new one.
●Do not put a new label on top of an
existing one.
●Attach the label only in the specified
location.
To prevent recorded MiniDiscs from
being erased accidentally
Slide the accidental erase prevention tab, located
on the side of the MiniDisc, in the direction indi-
cated by the arrow.
●The MiniDisc will then be protected against accidental
erasure.

Useful Features
About track numbers
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).
●Track numbers may not be created in proper places,
depending on the source to be recorded from, such as
signals with noise.
●The track numbers on the playback side may not match
the track numbers recorded on the MiniDisc.
About sampling rate converter
This unit incorporates a sampling rate converter.
When this unit is connected to digital equipment such as
digital radios or DAT tape recorders that use a different
sampling frequency (32 kHz or 48 kHz), recordings can
still be made. (The sampling frequency of this unit is 44.1
kHz.)
Note for digital recording
You can not copy a MiniDisc that you recorded from digital
inputs to another MiniDisc or DAT. It is prevented by the
SCMS(SerialCopy Management System). Recordingfrom
analogue inputs is not affected.
●Whenrecording, if a programmed playback is performed
by the source or playback is performed by selecting
tracks manually, the MiniDisc track numbers may not be
the same as on the source.
●Track numbers may not be created properly, depending
on the connected stereo system.
