BEFORE RECORDING

■ Type of recording

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

(1) Analog recording

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

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

● Cable required: Connecting cable in­cluded with this unit

AUDIO OUT

Playback side

(2) Digital recording

Connect the unit to equipment that has an
optical output jack using an optical digital
cable (available optionally). Using an opti­cal signal to transfer the music to a Mini­Disc allows very high quality recording.

● Main equipment: DSS 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 batteries, if the head­phones volume level is set to “0", the

battery consumption will be less than
when listening to the recording while 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.

RECORDING USING THE CABLE INCLUDED WITH THE UNIT

■ Recording from CDs or MDs (Synchro recording)

● Synchro recording is a method that detects the playback sound from the source

equipment. When sound is present, it automatically starts the recording. When the
source is silent, the recording will be paused.

● Adjust the recording level so that the
maximum sound volume from the
source makes the reading swing some­where between -4 dB and 0 dB.

● To record from a CD, first adjust the
recording level. Then put the equip­ment connected to this unit into the
playback stand-by mode.

5Press the ENTER/F.PLAY/SYNCHRO

button.

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 9)

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
while 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 while
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.

Notes:

● Whenever any button is pressed, the
remote control display will light for
about 4 seconds.

● The REC button does not light.
