RDS is a broadcasting service which a growing number of FM stations provide.
These FM stations send additional signals along with their regular programme
signals. They send their station names, and information about the type of
programme such as sports or music, etc.
When tuned to an RDS station, “RDS” and the station name will be displayed.
“TP” (Traffic Programme) will appear on the display when the received broadcast car-
ries traffic information, and “TA” (Traffic Announcement) will appear whilst a traffic infor-
mation is on air.
“EON” will appear whilst the EON (Enhanced Other Networks information) data is broad-
cast.

What is a MiniDisc?
The disc is stored in a cartridge. You can handle it easily without worrying about dust,
fingerprints, etc. However, dust entering the opening of the cartridge, dirt on the car-
tridge, warping, etc. may cause malfunctions. Please note the following.
To prevent recorded MiniDiscs from being
erased accidentally
Slide the accidental erase prevention tab, located on the side of the MiniDisc, in the
direction indicated by the arrow.
The MiniDisc will then be protected against accidental erasure.
To add a recording to such a MiniDisc, slide the accidental erase prevention tab back
to its original position.
Helpful tip when attaching a label
When attaching a label to a MiniDisc cartridge, be sure to note the following. If the label
is not attached properly, the 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.
Types of discs
There are two types of discs: playback-only and recordable types.
 Playback-only MiniDisc:
This type of MiniDisc is used for commercially available
prerecorded music. This is the same kind of optical disc
as CDs. Playback is performed using an optical pickup.
(Recording and editing are not possible.)
 Recordable MiniDisc:
This is a “raw disc” on which recording can be performed.
A magneto optical disc is used. Recordings are made
using a laser and magnetic field. Repeated recording is
possible.
MiniDisc System Limitations
Even if the maximum record-
ing time of a MiniDisc has not
been reached, “TOC FULL”
may be displayed.
Even if the maximum record-
ing time of a MiniDisc has not
been reached, “DISC FULL”
may be displayed.
Even if several short tracks
are erased, the remaining re-
cording time may not show an
increase.
Two tracks may not be com-
bined in editing.
The total of the recorded time
and time remaining on a disc
may not add up to the maxi-
mum possible recording time.
If recorded tracks are fast re-
versed or fast forwarded, the
sound may skip.
In the MD system, the delimiter of the recording area
on a MiniDisc is programmed in a TOC. If partial eras-
ing, recording and editing are repeated several times,
TOC information will fill up, even though the number
of tracks has not reached the limit (255 tracks), and
further recording will be impossible. (If you use the
all erase function, this MiniDisc can be used from
the beginning.)
If there is any flaw on the MiniDisc, that part is auto-
matically excluded from the space available for re-
cording. Therefore, the recording time becomes
shorter.
When the remaining recording time of a disc is dis-
played, short tracks less than 12 seconds long may
not be included in the total.
For MiniDiscs on which repeated recording and ed-
iting operations were performed, the COMBINE func-
tion may not work.
A track recorded from a CD (digital recording) and a
track recorded from a radio or other equipment (ana-
logue recording) cannot be combined.
A cluster (about 2 seconds) is normally the minimum
unit of recording. So, even if a track is less than 2
seconds long, it will use about 2 seconds of space
on the disc. Therefore, the time actually available for
recording may be less than the remaining time dis-
played.
If there are scratches on discs, those sections will
be automatically avoided (no recording will be placed
in those sections). Therefore, the recording time will
be reduced.
A MiniDisc which has been recorded or edited re-
peatedly may skip during fast reverse or fast forward.
Recordable
Recording
prevented
A Shutter will be used on
only one side (back).
Shutters will be used on
both sides.

System Connections (For CD-MD3000W Only)
Setting the AC voltage selector
Check the setting of the AC voltage selector located on the rear panel before plug-
ging the unit into an AC socket. If necessary, adjust the selector to correspond to the
AC power voltage used in your area.
 
Turn the selector with a screwdriver until the appropriate voltage number
appears in the window (110 V, 127 V, 220 V or 230 V - 240 V AC).
Connecting the AC power lead
After making all connections, plug the unit. If you plug the unit first, the unit
will enter the demonstration mode 
Notes:
Plug the AC power lead into an AC socket, after any connections.
Unplug the AC power lead from the AC socket if the unit will not be in use for a pro-
longed period of time.
AC Plug Adaptor
In areas (or countries) where an AC socket as shown in illustration   is used, con-
nect the unit using the AC plug adaptor supplied with the unit, as illustrated. The AC
plug adaptor is not included in areas where the AC wall socket and AC power plug
can be directly connected (see illustration  ).
Note for users in Australia and New Zealand:
An AC plug adaptor is not supplied if the lead has an Australian Standard plug.
