" The 1-bit digital signal is sent to a constant voltage circuit directly from a high-order
modulation circuit.
The amplifier transmits and amplifies the signal, and
allows extremely natural and clear sound with little
deterioration.
" High-quality sound is achieved by vast improvements
in the sound resolution. The speed and the smoothness of rise of the sound are consequently ensured.

" 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 performed, replace the battery with a new one (ADN70BT).
" 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 discharged.
" 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 battery 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 compartment of this product.
To charge the battery fully, continue charging for about 2
more hours. In this case, you do not need to press the

The ATRAC (Adaptive TRansform Acoustic Coding) system compresses the sound data into 1/5 by cutting out
the inaudible sound. Since the sound is selected based
on psychoacoustics masking, the sound quality is not
impaired. This unit is equipped with the ATRAC3 compressing system that can reduce the sound data to 1/10
or 1/20 of its original size. By employing this system, 2
times and 4 times long recordings are enabled in stereo
mode.
You can select the recording mode from stereo recording,
2 times long recording, 4 times long recording, and monaural recording. Recordable time varies depending on
the recording mode. If the tracks are recorded on an 80minute MiniDisc, its recording time changes as follows:

Notes:
" In monaural recording, the sound on the right and left
channels is mixed even if the input source is in stereo.
Although you can hear the stereo sound from the earphones, the recorded sound is monaural.
" Tracks recorded in 2 times long recording and 4
times long recording modes cannot be played with
the unit that does not support these modes. On
such a unit, no sound is heard. (The operation may
vary depending on the unit.)
" Tracks recorded in monaural cannot be played on a
unit that does not support monaural playback.
Special compression methods are used to achieve 4
times long recording. This may cause some noise to be
recorded occasionally. When the highest quality is
required, stereo or LP2 recording is recommended.

-About Net MD-
The USB is adopted to ensure high compatibility of PCs
and MDs.
Audio data saved on the hard disk of a PC can be transferred to a Net MD-compatible recorder using the provided software "BeatJam".
Not only the basic operations but also the title editing of
audio data on an MD can be performed via the PC.

Digital audio data can be imported into the hard disk of a
PC in the following methods:
" Converting the music downloaded via the music distribution service on the Internet into ATRAC3 of the
OpenMG system.
" Recording an audio CD via the CD-ROM drive of a PC
on the hard disk. (Compressing data with the ATRAC3
sound compressing system)
" Converting the existing MP3, WAV audio files into
ATRAC3 of the OpenMG system.
The saved audio data can be played on the existing MD
player, as its recording method is not changed when
being recorded on an MD. (To play audio data saved in
the MDLP mode, the MDLP-support MD player is
required.)
All the audio data managed by "BeatJam" is encrypted by
the OpenMG system and recorded on the hard disk of
the PC, which prevents its unauthorised use or distribution.

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 maximum 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.
A MiniDisc on which recording and editing are repeated may not allow the combine function.
Sound skips in fast reverse/forward.
If 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.

Maintenance
! Cleaning
When this product is subjected to strong external interference (mechanical shock, excessive static electricity,
abnormal supply voltage due to lightning, etc.) or if it is
operated incorrectly, it may malfunction.
When the unit becomes dirty
Clean it with a soft cloth. When the unit is excessively
dirty, use a soft cloth dampened in water (external surfaces only).
Should a failure occur, the lid may not open by sliding the
OPEN lever.
Clean the plugs and the connecting sockets.
If the plugs or sockets are dirty, noise may be heard.
Cleaning will prevent noise.
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.
4. Plug the AC adaptor back into the wall socket.
5. After about 30 seconds, press the
button as a test.
! Moisture condensation
When the unit has condensation inside, the disc signals
cannot be read, and the unit may not function properly.
Caution:
" Do not use chemicals for cleaning (petrol, paint thinner, etc.). It may damage the cabinet finish.
" Do not apply oil to the inside of the unit. It may cause
malfunctions.
References
! If trouble occurs
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.
