Notes
• If you press x/CHARGE immediately after
charging has completed, charging will begin
again. If this happens, press x/CHARGE
again to stop the charging operation since the
battery is already fully charged.
• Charging stops when you try to operate the
recorder during charging.
• Be sure to use the supplied AC power adaptor.
• Charging time may vary depending on the
battery condition.
• When a rechargeable battery is charged for the
first time or charged after a long period of
disuse, battery life may be shorter than usual.
Repeat discharging and recharging a few
times. The battery life should return to
normal.
• When the battery life of a fully charged
rechargeable battery becomes about half the
normal life, replace it.
• Remove the rechargeable battery from the
recorder when it is not to be used for a long
time.

Recording an MD right away!
Connect to a digital source using an optical cable to make digital
recordings. Digital recording is possible even from digital equipment
with different sampling rates, such as a DAT deck or a BS tuner, using
the built-in sampling rates converter (see “Note on digital recording”
(page 59)). To record from an analog source, see “Recording with
analog input (line cable required)” (page 22). It is recommended to
use the supplied AC power adaptor when recording.

Two ways of connecting to a sound source
The input jack of this recorder works as both digital and analog input jacks. Connect the
recorder to a CD player or a cassette recorder using either digital (optical) input or analog
(line) input. To record, see “Recording an MD right away!” (page 16) to record using
digital (optical) input, and “Recording with analog input (line cable required)” (page 22) to
record using analog (line) input.
