Notes:
● When making important recordings, it is
recommended that you use the AC
adaptor. A fully charged rechargeable
battery or alkaline batteries should be
loaded into the unit. Then, even if a
power failure occurs, the power source
will switch over to the battery automatically.
● When using the rechargeable battery or
the alkaline batteries, if the volume level
is set to “0”, the battery consumption will
be less than when listening to the recording whilst it is being made.
● Insert each plug firmly. If the connections
are poor, the recording may not be made
properly. Always keep the plugs clean.
If the plugs are dirty, electrical noise may
be recorded.
■ Types of discs
There are two types of discs: playback-only
and recordable discs.
● Playback-only MiniDisc:
This type of MiniDisc usually contains
commercially available pre-recorded
music. This is the same kind of optical
disc as CDs. Playback is performed using an optical pickup.
(Recording and editing are not possible.)
There will only
be a shutter on
one side (the back).
● Recordable MiniDisc:
This is a “raw disc” on which recording
can be performed.
This is a magneto-optical disc.
Recordings are made using a laser and
a modulated magnetic field. Repeated
recording is possible.
Shutters can be
seen on both
sides of this
type of disc.
■ To prevent recorded discs from
being erased accidentally
Slide the accidental erase prevention tab,
located on the side of the disc, in the direction indicated by the arrow.
● The disc will then be protected against
accidental erasure.

● If a MiniDisc is protected against accidental erasure. (page 10)
About the recording level:
● If the recording level is too low, the
playback sound volume may be too
low to hear well. If it is too high, the
playback sound may be greatly distorted. Since digitally recorded CDs
have a large dynamic range (the volume can vary tremendously from very
soft to extremely loud), do not set the
recording level any higher than is
necessary.
Precautions when recording:
● Do not jar or bump the main unit whilst
recording. Otherwise, the recording
may be unusable.
● Depending on the strength and type
of playback signal in the original recording, the new recording may not
begin or pause at the correct point
when in the synchro mode. If this happens, try making a manual recording.
Precautions when inserting a
MiniDisc:
● To insert a MiniDisc, push on the
middle of the edge of the disc whilst
holding it parallel to the main unit.
● If any resistance is felt, do not try to
force the MiniDisc into the unit. It may
additional more problems. If resistance is felt, remove the MiniDisc and
try reloading it.
To interrupt recording:
Press the 06 button whilst recording.
● The unit will enter the recording standby mode.
● T o resume recording, press the 06 but-
ton again.
The track number will be increased by

ABOUT THE TOC
The TOC (an abbreviation for Table of Contents) is information about the track numbers and recorded areas that allow the unit
to find musical selections or sounds. The
entire MD is controlled by the information
in this TOC, which enables the unit to find
the beginning of a track quickly or to record
automatically in a vacant area.
● The TOC is recorded in a specific area
on a MiniDisc, which is not used for
sound recording.
■ About TOC recording
When you start recording or editing,
“TOC” will appear in the display.
■ When is the TOC recorded?
The revised TOC will be recorded on the
disc automatically when you press the
■/:OFF button whilst in the stop mode. This
will also turn the power to this unit off.
TOC display
This indicates that information in the TOC
is now being changed according to recording or editing being performed.
● The changed TOC information will not
be recorded on the MiniDisc right
away.
Notes:
● Whilst “TOC” is displayed, the MiniDisc
should not be removed. Turn the power
off first, and then remove the MiniDisc.
● The edited contents can be stored on
the disc after several editing steps have
been performed.
The power will be turned off after the TOC
has been recorded on the disc.
Caution:
● Whilst “TOC” or “TOC EDIT!” is displayed, do not do any of the following.
– Do not jar or bump the main unit.
– Do not unplug the AC adaptor.
– Do not remove the rechargeable bat-
tery or alkaline batteries.
If you do, the changes in the recorded
or edited contents will be lost if the TOC
information is not recorded properly.

information stored in memory is used.
About the auto power save function:
This is a function used to save power when
using the unit with the rechargeable battery or the alkaline batteries. Whilst in the
auto power save mode, 5 - 10 seconds of
sound information is stored in memory.
When the auto power save function is disabled, 10 seconds of sound information is
always stored in memory. (When the AC

WHAT IS A MINIDISC?
A MiniDisc is a disc inside a protective cartridge. Y ou can handle it freely without worrying about dust, fingerprints, etc.
However, if dust enters the opening of the
cartridge, or there is excessive dirt on the
cartridge, or the cartridge becomes warped,
you may experience malfunctions.
Please note the following.
■ Handling the MiniDisc
Do not touch the disc directly!
Do not open the shutter or touch the disc
directly.
If the shutter is opened forcibly, it may break.
Disc
Shutter
● Never disassemble a MiniDisc.
Cartridge
■ Where not to store discs
Do not store discs in places with high temperatures or humidity. Specifically, do not
leave discs in places exposed to direct sunlight or in cars with the doors and windows
closed.
Do not leave discs in places where sand
can get into the cartridge easily (e.g.,
beaches).
■ Helpful tip when attaching a label
When attaching a label to an MD 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 possible 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.
TROUBLESHOOTING
● Attach the label only in the specified location. (If it is not within the specified
area, it may cause the disc to jam in the
unit.)
■ Regular cleaning
If the surface of the cartridge becomes
dusty or dirty, clean it with a dry cloth.
TROUBLESHOOTING
■ Moisture condensation
In the following cases, condensation
may form inside the unit.
● Shortly after turning on a heater.
● When the unit is placed in a room where
there is excessive steam or moisture.
● When the unit is moved from a cool
place to a warm place.
* MD-MT20H FOR UK(22-42) 99.3.11, 2:30 PM38
When the unit has condensation inside,
the disc signals cannot be read, and the
unit may not function properly.
● If this happens, remove the disc.
The condensation should evaporate in
approximately 1 hour. The unit will then
function properly.

MINIDISC SYSTEM LIMITATIONS
MiniDiscs are recorded using a different system than is used for cassette tapes or DAT
recordings. Therefore, the following conditions may be encountered, depending on how
the disc has been recorded or edited. These are due to system limitations, and should be
considered normal.
When the number of tracks used reaches
the limit, regardless of the remaining re-
Even if the maximum recording
time of a MiniDisc has not been
reached, “DISC FULL” or “TOC
FULL” may be displayed.
Even if the number of tracks and
the recording time have not
reached the limit, “DISC FULL”
may be displayed.
Even if several short tracks are
erased, the remaining recording
time may not show an increase.
Two tracks may not be combined
in editing.
The total of the recorded time and
time remaining on a disc may not
add up to the maximum possible
recording time.
When recorded tracks are played
back using the cue and review operations, some sounds may be
skipped.
A track number can be created in
the middle of a track.
cording time, further recording will be
impossible.
(Maximum number of tracks: 255)
If a MiniDisc has been recorded or edited repeatedly or if a MiniDisc has
scratches on it, it may not be possible to
record the maximum number of tracks on
it.
If there are scratches on a disc, the unit
will automatically avoid recording in those
areas. The recording time will be reduced.
When the remaining recording time of a
disc is displayed, short tracks less than
12 seconds long may not be included in
the total.
For MiniDiscs on which repeated recording and editing operations were performed, the COMBINE function may not
work.
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
displayed.
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.
For MiniDiscs on which repeated recording and editing were performed, some
sounds may be skipped whilst cueing and
reviewing.
If there are scratches or dust on a
MiniDisc, the track numbers following that
track will be increased by one.
