About ATRAC

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.



About the recording 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 Recording mode Recording

SP Stereo MAX. 80 min. LP2 2 times long (stereo) MAX. 160 min. LP4 4 times long (stereo) MAX. 320 min. MONO Monaural MAX. 160 min.



Caution for 4 times long recording

time

(LP4)

Special compressing method allows the 4 times long recording to realise long-time stereo recording. Therefore, some noise is recorded occasionally. If sound quality should be emphasised, stereo recording or 2 times long recording is recommended.

Stamping titles from another MiniDisc

Before stamping

When there are 2 MiniDiscs on which the same tracks are recorded, you can transfer the character information (disc and track names) of the Master MiniDisc to another MiniDisc (for stamping).

1. What is a master MiniDisc?

A recordable MiniDisc that contains tracks and character information. (You cannot transfer the information from a playback-only MiniDisc.)

2. What is a MiniDisc for stamping?

A MiniDisc that contains the same tracks in the same order as the master MiniDisc. (Make sure that the total number of tracks of the master MiniDisc and the one for stamping are the same.)

Rechargeable battery



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 (ADN55BT).



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.

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 recording time left.

The remaining recording time does not increase even though you erased tracks.

The total of the recorded time and the remaining time does not match the maximum recordable time.

Combine function does no t w or k .

Sound skips in fast reverse/forward.

A track number is created in the middle of a track.

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 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.

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.

(The number of seconds indicates that in the stereo recording mode (SP). It varies depending on the recording mode.)

A MiniDisc on which recording and editing are repeated may not allow the combine function.

If one track is divided and recorded in separate places on a repeatedly recorded or edited MiniDisc, sound may skip.

A track number may be created if there are scratches or dust on the MiniDisc.

If trouble occurs

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.

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 and reoperate the unit.



Moisture condensation

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.

Maintenance



Cleaning

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).

Clean the plugs and the connecting sockets.

If the plugs or sockets are dirty, noise may be heard. Cleaning will prevent noise.

Caution:
