noise. If the volume is adjusted according to your usual  
expectations of noise, high volume may damage your  
hearing.

Helpful tip when attaching a label  
When attaching a label to an MiniDisc cartridge, be sure to  
note the following. If the label is not attached properly, the  
MiniDisc may jam inside the unit and it may not be pos-  
sible to remove it.  
U
Note:  
If the label peels off or partially lifts  
away, replace it with a new one.  
Do not put a new label on top of an  
existing one.  
Attach the label only in the specified  
location.  
When making digital recordings using a CD player or an  
MiniDisc player, track numbers will be created automati-  
cally regardless of the setting of the auto marker func-  
tion.

About track numbers  
1. Track numbers are created automatically during re-  
cording via the analogue connection when a silence  
of 1 second or more is detected (Auto marker func-  
tion). A series of tracks can be recorded as one by  
disabling the auto marker function see page 18.  
Track numbers may not be created properly, depending  
on the connected stereo system.

Other Features and Caution  
Resuming auto play  
Rechargeable battery  
When you stop playback and replay the MiniDisc  
without removing it, playback starts from the point  
you stopped it.  
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.  
The rechargeable battery can be charged approximately  
300 times.  
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).  
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 battery life will recover  
with normal use i.e. charging and discharging.  
To avoid shortening the service life of the battery only  
recharge the battery after it has been completely dis-  
charged.  
If the rechargeable battery is used in a cold environment,  
the operating time will be reduced.  
Do not carry the battery in your pocket or a bag together  
with metal objects (keys, coins, jewelry, etc.). The bat-  
tery may short out and generate significant amounts of  
heat.  
Do not short-circuit the terminals as they will become  
very hot and will damage the battery.  
Do not drop or subject the battery to shock.  
Do not insert objects (metal etc.) into the battery com-  
partment of this product or into the rechargeable battery.

MiniDisc System Limitations  
The unit may have the following symptoms whilst 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 re-  
cording time.  
If the MiniDisc is recorded or edited repeatedly or if it has scratches (record-  
ing 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 maxi-  
mum recordable time.  
One cluster (approximately 2 seconds) is the minimum unit for recording.  
For example, a 3-second track uses 2 clusters (approximately 4 seconds).  
Therefore, the actual recordable time may be shorter than the displayed  
time.  
Combine function does not work.  
Sound skips in fast reverse/forward.  
A MiniDisc on which recording and editing are repeated may not allow the  
combine function.  
R
One track is divided and recorded in separate places on a repeatedly re-  
corded 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.

Troubleshooting : continued  
If trouble occurs  
Moisture condensation  
When this product is subjected to strong external in-  
terference (mechanical shock, excessive static elec-  
tricity, abnormal supply voltage due to lightning, etc.)  
or if it is operated incorrectly, it may malfunction.  
When the unit has condensation inside, the disc signals  
cannot be read, and the unit may not function properly.  
In the following cases, condensation may form inside the unit.  
Shortly after turning on a heater.  
When the unit is placed in a room  
where there is excessive steam  
or moisture.  
If such a problem occurs, do the following:  
1. Unplug the AC adaptor from the wall socket.  
2. Remove the battery.  
3. Leave the unit completely unpowered for approximately  
30 seconds.  
When the unit is moved from a  
cool place to a warm place.  
To remove condensation:  
4. Plug the AC adaptor back into the wall socket and  
reoperate the unit.  
Remove the MiniDisc and leave the unit for approxi-  
mately 1 hour. The condensation should evaporate and  
the unit will work properly.
