for a long period, the operating time may
be shorter than normal.The battery life
will recover with normal use i.e. charg-
ing and discharging.
● To avoid shortening the service life of the
battery only recharge the battery after it
has been completely discharged.
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.
■ Synchro recording
1
Connect the external equipment.
2
Insert a recordable MiniDisc, and then
press the REC button.
3
Put the equipment connected to this unit
into the playback stand-by mode.
4
Press the ENTER/SYNC button.
5
Start the playback on the equipment
connected to this unit.
■ Manual recording
1
Place the unit in the recording stand-by
mode. (Perform steps 1 - 3 in the “Syn-
chro recording” section.)
2
Press the button, and then start
playback on the equipment connected
to this unit.
● When recording from digital inputs, it is
not necessary to adjust the recording
level.
Notes:
● This unit incorporates a sampling rate
converter.
When this unit is connected to digital
equipment such as CS/BS tuners or DAT
tape recorders that use a different sam-
pling frequency (32 kHz or 48 kHz), re-
cordings can still be made. (The sam-
pling frequency of this unit is 44.1 kHz.)
● When making a digital recording from a
portable CD player (if the player has a
sound skip prevention function and this
function is turned on) the optical output
will drop out and digital recording will not
be possible. Be sure to turn the sound
skip prevention function off.
There are cases where digital recording
may be impossible.
In the following cases digital recording is
impossible, even if you are using digital
cables.
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).
