as TVs or loudspeakers.

● Places exposed to vibration.

● Places where sand can easily enter the

inside of the unit (beaches etc.).

● If the unit is used near radio tuners or
TVs, noise and/or picture interference
may result. If you experience these
problems, move the unit away from
such devices.

■ Concern for others when

listening to MiniDiscs

If you are enjoying listening to music, the
sound escaping from your earphones may
annoy people around you.
If you are using the unit in particularly
crowded places (such as on trains or
buses), reduce the volume to avoid annoy­ing people around you.

■ Precautions

BEFORE RECORDING

■ Type of recording

Two types of recording are possible: “Digital recording” and “Analogue recording”. There
are different cables and connections for each type of recording, depending on the sockets
on the equipment being connected to the unit.

(1) Analogue recording

Connect the unit to equipment that has a
line output socket, using the analogue
cable included with this unit.

● Main equipment: CD player, MD player,
radio cassette player, etc.

● Cable required: Analogue cable in­cluded with this unit

AUDIO OUT

RL

Playback side

(2) Digital recording

Connect the unit to equipment that has an
optical output socket using the optical dig­ital cable included with this unit. Using an
optical signal to transfer the music to a
MiniDisc allows very high quality record­ing.

● Main equipment: CS/BS tuner, CD
player, MD player, etc.

● Cable required: Optical digital cable

■ 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 magneto­optical 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.

● To add a recording to such a disc, slide
the accidental erase prevention tab

Protected against
accidental erasure

back to its original position.

Notes:

● When making important recordings, it
is recommended that you use the AC
adaptor. A fully charged rechargeable
battery should be loaded into the unit.
Then, even if a power failure occurs,
the power source will switch over to the
rechargeable battery automatically.

● When using the rechargeable battery
or the alkaline battery, if the head­phones 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.

Recordings can not be made in the
following situations:

● Recording on a playback-only
MiniDisc (commercially available
music)

● 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 cause more problems. If resis­tance is felt, remove the MiniDisc
and try reloading it.

Note:

● Whenever any button is pressed, the
remote control display will light for
about 7 seconds.
