BEFORE RECORDING
■ Type of recording
(2) Digital recording
Connect the unit to equipment that has an
optical output socket using the optical digi-
tal cable included with this unit. Using an
optical signal to transfer the music to a
MiniDisc allows very high quality recording.
Two types of recording are possible: “Digi-
tal recording” and “Analogue recording”.
There are different cables and connections
for each type of recording, depending on
the sockets on the equipment being con-
nected to the unit.
● Main equipment: CD player, MD player,
Digital radio, etc.
● Cable required: Optical digital cable
included with the unit or optional optical
digital cable AD-M2DC.
(1) Analogue recording
Connect the unit to equipment that has a
line output socket, using the analogue cable
included with this unit.

Notes:
● Recordable MiniDisc:
This is a “raw disc” on which recording
can be performed.
● 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 automati-
cally.
● 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 re-
cording whilst it is being made.
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.
● 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.
■ To prevent recorded discs from
being erased accidentally
Slide the accidental erase prevention tab,
located on the side of the disc, in the direc-
tion indicated by the arrow.
● The disc will then be protected against
accidental erasure.
■ 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 us-
ing an optical pickup.
(Recording and editing are not possible.)
Protected against
accidental erasure
There will only
be a shutter on
one side (the back).
● To add a recording to such a disc, slide
the accidental erase prevention tab back
to its original position.

following situations:
● Recording on a playback-only
MiniDisc (commercially available
music).
● If a MiniDisc is protected against ac-
cidental erasure. (page 10)
About the recording level:
To remove the MiniDisc:
● 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 dis-
torted. Since digitally recorded CDs
have a large dynamic range (the vol-
ume can vary tremendously from very
soft to extremely loud), do not set the
recording level any higher than is
necessary.
Turn off the power and move the OPEN
lever in the direction indicated by the arrow.

RECORDING USING THE OPTICAL DIGITAL CABLE
This is the method used for recording digi-
tal signals from CDs or MDs exactly as they
are stored on the original. Compared to re-
cordings made from analogue inputs, digi-
tal recordings have extremely high-quality
sound.
When you attempt to make a new digital
recording from a track that was digitally re-
corded on a MiniDisc.
● MiniDiscs are designed so that only first
generation digital copies can be made.
Further digital copies are prevented by
the SCMS (Serial Copy Management
System).

ABOUT TRACK NUMBERS
When recording, track numbers will be
created automatically.
When recording from digital inputs:
(CDs/MiniDiscs only)
(Auto marker function/Synchro marker
function)
Track numbers will be created automatically
for each track at the same point where track
numbers already exist on the CD or
MiniDisc.
When recording from analogue inputs:
(Including digital inputs other than
CDs or MiniDiscs)
(Synchro marker function)
A new track number will automatically be
created whenever 1 second or more of si-
lence occurs in the source.

spaces from the source, the track num-
bers may not be created at the correct
position, depending on the contents of
the source being recorded.
● Track numbers may not be created,
even when recording from digital inputs,
depending on the CD player used for the

ABOUT THE TOC
The TOC (an abbreviation for Table of Con-
tents) is information about the track num-
bers 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.
■ 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.
● 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.
The power will be turned off after the TOC
has been recorded on the disc.
TOC display
Caution:
● Whilst “TOC” or “TOC EDIT!” is dis-
played, 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.
This indicates that information in the TOC
is now being changed according to record-
ing or editing being performed.
● The changed TOC information will not
be recorded on the MiniDisc right
away.
If you do, the changes in the recorded
or edited contents will be lost if the TOC
information is not recorded properly.
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.

Precautions when making connec-
tions:
● Do not use any remote control unit,
except for the one included with this
unit.
● Do not remove the rubber pads from
the earphones.
● Insert each plug securely, all the way
in.
Caution:
● When the unit is not to be used imme-
diately after a MiniDisc has been in-
serted, or when you plan to carry the
unit, turn off the power or cancel the
auto-play function. Otherwise, the
auto-play function will be activated and
the battery will run down.
● Since the main unit and the AC adap-
tor can heat up during use, you should
avoid allowing the unit to be in direct
contact with your skin for any length
of time.
● Be sure to hold the plug when remov-
ing it. If you pull on the lead, it may
break, or the unit may malfunction.
Interrupted sound:
● This product is designed to eliminate
interruptions in the sound which can
be caused by vibrations. However, if
the unit is continuously exposed to
vibrations or mechanical shock, the
sound may be interrupted momen-
tarily.
When using the unit with a car adaptor:
● When you switch off the ignition key
during playback, the power to this unit
will also be turned off. Then, when the
ignition key is switched on, playback
will start from the beginning of the track
where playback was halted (Resume
auto-play function). However, the
power to the unit may not be turned
off when the ignition is turned off, de-
pending on the type of car.
When the sound is distorted:
● If the volume is too high whilst the
bass is being emphasised, the sound
may be distorted, depending on the
music on the track. If this happens,
decrease the bass level or lower the
volume level.
● If the volume is increased to “VOL 24”
or higher, the bass level will be ad-
justed automatically.
(This is done to reduce the distortion
in the sound.)

About the sound skip guard memory:
During playback, approximately 10 seconds
of information is stored in the semiconduc-
tor memory. Therefore, even when the
pickup cannot read information for a second
or two due to an external shock, the sound
will continue without interruption because the
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 bat-
tery 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 dis-
abled, 10 seconds of sound information is
always stored in memory. (When the AC
adaptor or a car adaptor is used, the infor-
mation storage time is always 10 seconds,
regardless of the auto power save mode.)
When the unit is used in places exposed to
excessive vibration, cancel the auto power
save function.
■ To cancel the auto power
save function
Power consumption can be reduced by
controlling the memory storage time. You
can cancel the auto power save function.

WHAT IS A MINIDISC?
A MiniDisc is a disc inside a protective car-
tridge. You can handle it freely without wor-
rying 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.
■ Where not to store discs
Do not store discs in places with high tem-
peratures or humidity. Specifically, do not
leave discs in places exposed to direct sun-
light 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).
Please note the following.
■ Handling the MiniDisc
Do not touch the disc directly!
Do not open the shutter or touch the disc
directly.
■ 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 shutter is opened forcibly, it may break.
Disc
Shutter
Cartridge
● If the label peels off or
partially lifts away, re-
place 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 lo-
cation. (If it is not within the specified
area, it may cause the disc to jam in the
unit.)
● Never disassemble a MiniDisc.
■ 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.
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.
● 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.

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-
cording time, further recording will be
impossible.
(Maximum number of tracks: 255)
If a MiniDisc has been recorded or ed-
Even if the maximum recording
time of a MiniDisc has not been
reached, “DISC FULL” or “TOC
FULL” may be displayed.
ited repeatedly or if a MiniDisc has
scratches on it, it may not be possible to
record the maximum number of tracks on
it.
Even if the number of tracks and
the recording time have not
reached the limit, “DISC FULL”
may be displayed.
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.
Even if several short tracks are
erased, the remaining recording
time may not show an increase.
For MiniDiscs on which repeated record-
ing and editing operations were per-
formed, the COMBINE function may not
work.
Two tracks may not be combined
in editing.
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 re-
cording may be less than the remaining time
displayed.
If there are scratches on discs, those sec-
tionswillbeautomaticallyavoided(norecord-
ing will be placed in those sections). There-
fore, the recording time will be reduced.
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 op-
erations, some sounds may be
skipped.
For MiniDiscs on which repeated record-
ing 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.
A track number can be created in
the middle of a track.
