„ About track numbers
z Track numbers may not be created in proper places,
depending on the source to be recorded from, such as
signals with noise.
z The track numbers on the playback side may not
match the track numbers recorded on the MiniDisc.
z When recording, if a programmed playback is per-
formed by the source or playback is performed by

ing on the connected stereo system.
„ About sampling rate converter
This portable MD incorporates a sampling rate converter,
which means it can record from digital radios or DAT tape
recorders.
„ Note for digital recording
You cannot copy a MiniDisc that you recorded from digital
inputs to another MiniDisc or DAT. It is prevented by the
SCMS (Serial Copy Management System). Recording
from analog inputs is not affected.

cording via the analog connection when a silence of
1 second or more is detected (Auto marker function).
A series of tracks can be recorded as one by disa-
bling the auto marker function, see page 21.

When recording from the microphone, track numbers will
be created automatically at regular intervals (default set-
ting: approximately every 5 minutes). During a mic syn-
chro recording, the unit pauses when a silence lasts for 3
seconds or more, and creates a track number.
Changing intervals between tracks
Example: Set to "5 minutes".
During a mic manual recording
Timed auto marks will be created every 5 minutes.
During a mic synchro recording
If a silence lasts for 3 seconds or more, a timed auto
mark will be created 5 minutes after the previous mark is
created.
Creating track numbers manually
Press the REC button while recording.

When a recording is paused or while re-
cording, press the EDIT button repeatedly.
The interval between marks may vary slightly com-
pared with the actual recording time.

The unit provides the following functions when you
use it with the separately available car adaptor (AD-
CA20X) (when the rechargeable or alkaline battery is
removed):
„ Rechargeable battery
z
A rechargeable nickel-metal hydride battery is the only
kind that can be used. Even if the battery is not used,
you should charge it at least once every three months
because of the special quality of this battery.
z
The rechargeable battery can be charged approxi-
mately 300 times.
z When the operating time is reduced to about half the
normal amount of time, even after a full charge is per-
formed, replace the battery with a new one (AD-
N70BT).
z
When the battery is charged for the first time or is
charged after not being used for a long period, the
operating time may be shorter than normal. The bat-
tery life will recover with normal use i.e. charging and
discharging.
z To avoid shortening the service life of the battery, only
recharge the battery after it has been completely dis-
charged.
z If the rechargeable battery is used in a cold environ-
ment, the operating time will be reduced.
z Do not carry the battery in your pocket or a bag
together with metal objects (keys, coins, jewelry, etc.).
The battery may short out and generate significant
amounts of heat.
z Do not short-circuit the terminals as they will become
very hot and will damage the battery.
z
Do not drop or subject the battery to shock.
z Do not insert objects (metal etc.) into the battery com-
partment of this product or into the rechargeable bat-
tery.

ble MD also turns off. (It may not work with some types

-MiniDisc System Limitations-
MiniDisc System Limitations
The unit may have the following symptoms while recording or editing. The unit is not out of order.
SYMPTOM LIMITATIONS
"DISC FULL" or "TOC FULL" appears
even though the MiniDisc still has re-
cording time left.
More than 255 tracks (maximum) cannot be recorded regardless of
the recording time. If the MiniDisc is recorded or edited repeatedly or
if it has scratches (recording skips scratched parts), you may not be
able to record the maximum tracks above.
The remaining recording time does not
increase even though you erased
tracks.
The unit does not count non-recorded portions that last 12 or fewer
seconds to display the remaining recording time. The time may not
increase even if you erase short tracks.
The total of the recorded time and the
remaining time does not match the max-
imum recordable time.
One cluster (approximately 2 seconds) is the minimum unit for re-
cording. For example, a 3-second track uses 2 clusters (approxi-
mately 4 seconds). Therefore, the actual recordable time may be
shorter than the displayed time.
Combine function does not work. A MiniDisc on which recording and editing are repeated may not al-
low the combine function.
Sound skips in fast reverse/forward.
One track is divided and recorded in separate places on a repeatedly
recorded or edited MiniDisc. Sound may skip.
A track number is created in the middle
of a track.
A track number may be created if there are scratches or dust on the
MiniDisc.
