that do not support these modes, playback will not start and “LP:” will appear
on the display.
• Sound recorded through digital (optical) input can be monitored in stereo
through headphones/earphones, etc.
• When you record in LP4 mode, momentary noise may be produced on very
rare occasions with certain sound sources. This is because of the special
digital audio compression technology that enables a recording time 4 times
longer than normal. If noise is produced, it is recommended that you record
in normal stereo or LP2 mode to obtain better sound quality.

Additional information
Precautions
On safety
Do not put any foreign objects in the DC IN 3V jack.
On power sources
• Use house current, Nickel Cadmium rechargeable battery, LR6 (size AA)
battery, or car battery.
• For use in your house: Use the AC power adaptor supplied with this recorder.
Do not use any other AC power adaptor since it may cause the recorder to
malfunction.
Polarity of the
plug
• The recorder is not disconnected from the AC power source (mains) as long
as it is connected to the wall outlet, even if the recorder itself has been turned
off.
• If you are not going to use this recorder for a long time, be sure to disconnect
the power supply (AC power adaptor, dry battery, rechargeable battery, or car
battery cord). To remove the AC power adaptor from the wall outlet, grasp
the adaptor plug itself; never pull the cord.
On heat build-up
Heat may build up in the recorder if it is used for an extended period of time.
In this case, leave the recorder turned off until it cools down.
On installation
• Never use the recorder where it will be subjected to extremes of light,
temperature, moisture or vibration.
• Never wrap the recorder in anything when it is being used with the AC power
adaptor. Heat build-up in the recorder may cause malfunction or damage.
51
On the headphones/earphones
Road safety
Do not use headphones/earphones while driving, cycling, or operating any
motorized vehicle. It may create a traffic hazard and is illegal in many areas. It
can also be potentially dangerous to play your recorder at high volume while
walking, especially at pedestrian crossings. You should exercise extreme
caution or discontinue use in potentially hazardous situations.
Preventing hearing damage
Avoid using headphones/earphones at high volume. Hearing experts advise
against continuous, loud and extended play. If you experience a ringing in your
ears, reduce the volume or discontinue use.
Caring for others
Keep the volume at a moderate level. This will allow you to hear outside
sounds and to be considerate of the people around you.
On the MiniDisc cartridge
• When carrying or storing the MiniDisc, keep it in its case.
• Do not break open the shutter.
• Do not place the cartridge where it will be subject to light, extreme
temperatures, moisture or dust.
• Attach the supplied MD label only in the space designated for it on the disc.
Do not stick it on any other disc surface.
On cleaning
• Clean the recorder casing with a soft cloth slightly moistened with water or a
mild detergent solution. Do not use any type of abrasive pad, scouring
powder or solvent such as alcohol or benzene as it may mar the finish of the
casing.
• Wipe the disc cartridge with a dry cloth to remove dirt.
• Dust on the lens may prevent the unit from operating properly. Be sure to
close the disc compartment lid after inserting or ejecting an MD.
• To obtain the best sound quality, use a dry cloth to wipe the plugs of the
headphones/earphones or the remote control. Dirty plugs may cause sound
distortion or intermittent breaks in the sound.
52
Notes on batteries
Incorrect battery usage may lead to leakage of battery fluid or bursting
batteries. To prevent such accidents, observe the following precautions:
• Install the + and – poles of the batteries correctly.
• Do not try to recharge dry battery.
• When the recorder is not to be used for a long time, be sure to remove the
batteries.
• If a battery leak should develop, carefully and thoroughly wipe away battery
fluid from the battery compartment before inserting new ones.
On the lid of the battery compartment
The lid of the battery compartment is designed to detach from the main unit
when handled with great force. To reattach the lid to the main unit, follow the
steps below:
Slots
1
2
Projections
1 Place the lid so that the
projections on the lid aligned
with the slots on the main unit.
2 Fit the projection one by one
into the slot as shown in the
illustration.
Note on mechanical noise
The recorder gives off mechanical noise while operating, which is caused by
the power-saving system of the recorder and it is not a problem.
53
To protect a recorded MD
To record-protect an MD, slide open the tab at the side of the MD. In this
position, the MD cannot be recorded or edited. To record again, slide the tab
back so the tab is visible.

What is an MD?
How MiniDisc works
MiniDisc (MD) comes in two
types: premastered (prerecorded)
and recordable (blank).
Recordable MDs
Premastered MDs, recorded at
music studios, can be played back
almost endlessly. However, they
can’t be recorded on or over like
cassette tapes. To record, you must
use a “recordable MD”.
Recordable MDs, which use
magneto-optical (MO)
Premastered MDs
technology, can be recorded again
and again. The laser inside the
recorder applies heat to the MD,
demagnetizing the magnetic layer
of the MD. The recorder then
applies a magnetic field to the
layer. This magnetic field
corresponds exactly to the audio
signals generated by the connected
source. (The north and south
polarities equate to digital “1” and
“0”.) The demagnetized MD
adopts the polarity of the magnetic
field, resulting in a recorded MD.
Premastered MDs are recorded
and played like regular CDs. A
laser beam focuses on the pits in
the surface of the MD and reflects
the information back to the lens in
the recorder. The recorder then
decodes the signals and plays
them back as music.
How the MiniDisc got so small
The 2.5-inch MiniDisc, encased in
a plastic cartridge that looks like a
3.5-inch diskette (see illustration
above), uses a new digital audio
compression technology called
ATRAC (Adaptive TRansform
Acoustic Coding). To store more
sound in less space, ATRAC
extracts and encodes only those
frequency components actually
audible to the human ear.

Quick Random Access
Like CDs, MDs offer
“directory management system”
of floppy disks. In other words,
starting and ending addresses for
all music tracks recorded on the
disc are stored in this area. This
lets you randomly access the
beginning of any track as soon as
you enter the track number
instantaneous random access to
the beginning of any music track.
Premastered MDs are recorded
with location addresses
corresponding to each music
selection.
Recordable MDs are
manufactured with a “User
TOC Area” to contain the order of
the music. The TOC (Table of
Contents) system is similar to the
(AMS), as well as label the
location with a track name as you
would a file on a diskette.
