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:
Indication

MAX. 320 min.
MONO
Monaural
MAX. 160 min.
! Caution for 4 times long recording
(LP4)
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.

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

the unit that does not support these modes. On
such a unit, no sound is heard. (The operation may

The track will be moved, and the unit will be paused at

When a track has a name before dividing:
The two new tracks will have the same name. However, in
the "TOC FULL" condition, the second track may not be
named.
Total number of tracks that can be divided:
Each disc can hold up to 255 tracks. However, even if the
number of assigned tracks has not reached 255, it might
not be possible to make any further divisions of tracks.
To combine two non-adjacent tracks:
First, put the two tracks next to each other in the order
you want using the MOVE function. Then combine them
using the COMBINE function.
When one or both tracks to be combined have a
name:
The first track name will be used. However, when the first
track does not have a name, the second track name will
be used.
In the following cases, tracks may not be combined.
" Tracks recorded by different input modes/sources cannot be combined.
Examples:
" Digital recorded track and analogue recorded track.
" Different recording modes (stereo recording, 2 times
long recording, 4 times long recording, monaural recording).
" Tracks whose recording time is less than 12 seconds.

The unit provides the following functions when you
use it with the separately available car adaptor (ADCA20X) (when the battery is removed):
1. When you turn off the engine, the power of this portable
MD also turns off. (It may not work with some types of
cars.)
2. When you restart the engine, playback starts from the
beginning of the stopped track.
Clean the plugs and the connecting sockets.
If the plugs or sockets are dirty, noise may be heard.
Cleaning will prevent noise.

MiniDisc System Limitations
MD-MT280E
The unit may have the following symptoms whilst recording or editing. The unit is not out of order.
"DISC FULL" or "TOC FULL" appears
even though the MiniDisc still has recording 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 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.

" Is the unit connected properly to the other equipment?
" Is the AC adaptor unplugged or did a power failure
occur whilst recording or editing?
" Is the unit in the hold mode?
" Is an optical signal being output from the stereo system? Read the operation manual for the stereo system.
! If trouble occurs
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.
" When the unit is moved from a cool place to a warm
place.
To remove condensation:
Remove the MiniDisc and leave the unit for approximately 1 hour. The condensation should evaporate and
the unit will work properly.
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.
