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.
Protected against
accidental erasure
● To add a recording to such a disc, slide
the accidental erase prevention tab back
to its original position.

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
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
one each time you interrupt a recording.
