s Condensation

Sudden temperature changes, storage or operation in an extremely humid environment may cause condensation inside the cabinet (CD pickup, MD pickup, etc.) or on the transmitter window on the remote control. Condensation can cause the unit to malfunction. If this happens, leave the power on with no disc in the unit until normal playback is possible (about 1 hour) or wipe off any condensation on the transmitter window with a soft cloth before operating the unit.

s Care of compact discs

Compact discs are fairly resistant to damage, however mistracking can occur due to an accumulation of dirt on the disc surface. Follow the guidelines below for maximum enjoyment from your CD collection and player. q Do not write on either side of the disc, particularly the non-label side. Signals are read from the non-label side. Do not mark this surface. q Keep your discs away from direct sunlight, heat, and excessive moisture. q Always hold the CDs by the edges. Fingerprints, dirt, or water on the CDs can cause noise or mistracking. If a CD is dirty or does not play properly, clean it with a soft, dry cloth, wiping straight out from the centre, along the radius.

s Types of discs

There are two types of discs: playback-only and recordable type. q Playback-only MiniDisc: This type of MiniDisc is used for commercially available pre-recorded music. This is the same kind of optical disc as CDs. Playback is performed using an optical pickup. (Recording and editing are not possible.)

s High-speed access

A unique feature of the MiniDisc is the ability to locate the beginning of a desired track at high speed. This is because the track number and track name data is stored in a TOC (Table of Contents).
A shutter will be used on only one side (back).

TOC Sound data

q Recordable MiniDisc: This is a raw disc on which recording can be performed. A magneto optical disc is used. Recordings are made using a laser and magnetic field. Repeated recording is possible.

s Shock Resistant Memory

During playback, approximately 10 seconds of information is stored in the semiconductor memory. Therefore, even when the pickup cannot read information for a second or two due to an external shock, the sound continues without interruption because the information stored in memory is output.
Shutters will be used on both sides.
MINIDISC SYSTEM LIMITATIONS
"TOC FULL" may be displayed even if the maximum recording time on a MiniDisc has not been reached. In the MD system, the recording area on an MD is programmed in a TOC. If tracks are recorded, edited and partial erased repeatedly, the TOC will fill up with information about the tracks, even though the track limit (255 tracks) has not been reached. If that happens, further recording will be impossible. (If you use the all erase function, the MD can be reused as a blank MD.) If there is a flaw on the MiniDisc surface, that area is automatically excluded from the space available for recording. Therefore, the available recording time will be reduced. When the remaining recording time of a disc is displayed, short tracks less than 8 seconds long may not be included in the total. For MiniDiscs on which repeated recording and editing operations were performed, the COMBINE function may not work. Tracks recorded from a CD (digital recordings) and tracks recorded from some other equipment (analogue recordings) cannot be combined. A cluster (about 2 seconds) is normally the minimum unit of recording. So, even if a track is less than 2 seconds long, it will use about 2 seconds of space on the disc. Therefore, the time actually available for recording may be less than the remaining time displayed. If there are scratches on discs, those sections will be automatically avoided (no recording will be placed in those sections). Therefore, the recording time will be reduced. An MD which has been recorded or edited repeatedly may skip during fast reverse or fast forward.

q Shorten the disc or track name. q Load a disc. q Reload the disc. q Select another track. q Replace the disc. q Replace it with a recordable MiniDisc. q Edit only the sound. q Move the write protection tab back to its original position. q Press the ON/STAND-BY button to enter the stand-by mode, and wait for a while. q Replace the disc with another disc.

s Moisture condensation

In the following cases, condensation may form inside the unit. q Shortly after turning on a heater. q When the unit is placed in a room where there is excessive steam or moisture. q When the unit is moved from a cool place to a warm place. When the unit has condensation inside, the disc signals cannot be read, and the product may not function properly. q If this happens, remove the disc, and open the disc tray. The condensation should evaporate in approximately 1 hour. The unit will then function properly.
If 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 or the display may not function correctly. If such a problem occurs, do the following:
Unplug the AC power lead from the AC socket. Wait about 20 - 30 seconds and then plug the AC power
lead back into the AC socket.
Press the RESET button on the back of the unit.

Pen, pencil, etc.

s If a power failure occurs during recording
If the AC power plug is disconnected from the AC socket or a power failure occurs during recording (before the TOC information has been recorded on the disc), the audio portion being recorded at that time will be erased. When a recording is being added to a MiniDisc which already has a recording on it, if the TOC is not updated before the power failure, the added recording will be erased. q If a power failure occurs or the AC power lead is disconnected for about 10 minutes, when power is restored, the TOC will be written on the disc. q When the RESET button is pressed, all of the settings in memory will be erased. q If strange sounds, smells or smoke come out of the unit or if a foreign object falls into the unit, turn off the power, unplug the AC power lead from the AC socket, immediately. Contact the shop where you purchased the unit.

TRANSPORTING THE UNIT

When transporting the unit, proceed as follows:
Press the ON/STAND-BY button to turn the power on. Remove all discs CDs/MD from the unit. Press the RESET button on the rear of the unit.
q When the RESET button is pressed, all of the settings in memory will be erased. Make sure "TIME ADJUST" appears in the display, then press the ON/STAND-BY button to turn the power on again. Press the ON/STAND-BY button to enter the stand-by mode. Make sure the message on the display has changed from "GOOD BYE!" to "TIME ADJUST", and then unplug the AC power lead from the AC socket.
