POWER SOURCE Charging is needed. When you attempt to make a new digital recording from a track that was digitally recorded on a MiniDisc. ● MiniDiscs are designed so that only first generation digital copies can be made. Further digital copies are prevented by the SCMS (Serial Copy Management System). In the following cases digital recording is impossible, even if you are using digital cables. There are cases where digital recording may be impossible. Playback Digital cable Recording Analogue recording is possible. Digital cable Digitally recorded MiniDisc CD player, MD player, etc. Playback Recording Notes: ● When using the unit with an alkaline battery or a rechargeable battery, the battery indicator will not correctly display the remaining capacity for approximately 20 seconds after the power has been turned on. ● When the AC adaptor included with this unit or a separately available car adaptor is used, the battery indicator will not be shown. ● The number of bars shown in the battery indicator may increase or decrease, depending on the operation being performed. This is normal. ● When the rechargeable battery and the alkaline battery are used at the same time, the rechargeable battery is used first, then the alkaline battery. Since the battery indicator shows the remaining amount of the particular battery being used, the number of bars will increase when the unit switches to the alkaline battery. RECORDING USING THE OPTICAL DIGITAL CABLE ● When the battery is completely discharged, the whole battery indicator will flash. Recharge the battery or replace the alkaline battery with a new one. ● When the battery has run completely out, “BATT EMPTY” (main unit) and “Lo BATT” (remote control unit) will appear. Then, the power will be disconnected automatically. When the battery needs charging, it is impossible to start recording or editing. When the battery is completely charged < How to read the battery indicator > Battery indicator The remaining amount of battery charge is shown by the battery indicator ( ) during operation. ■ Checking the remaining amount of battery charge CONVENIENT OPERATION OF THE UNIT MD-MT821/W OPERATION MANUAL CAUSE Is the AC adaptor disconnected? Is the battery exhausted? Is the unit in the hold mode? Has condensation formed inside the unit? Is the unit being influenced by mechanical shock or by static electricity? –6– ● Has the track number or character information been written on the disc yet? ● Is the unit in the recording or editing mode? The MiniDisc cannot be ejected. 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 AC socket. 2. Remove the battery. 3. Leave the unit completely unpowered for approximately 30 seconds. ■ If trouble occurs Recording and editing are impossible. ● Is the battery exhausted? ● Is the unit being subjected to excessive vibration? Some sounds are skipped. If strange sounds, smell or smoke come out of the unit or an object is dropped into the unit, remove the AC adaptor from the AC socket immediately and contact an authorised SHARP service centre. 4. Plug the AC adaptor back into the AC socket and retry the operation. ● Is the MiniDisc protected against accidental erasure? ● 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 external equipment? Read the operation manual for the external equipment. ● Is the unit in the hold mode? ● Is the battery exhausted? ● Is the remote control unit plug or the earphone plug inserted firmly? ● Is the volume set too low? ● Is the remote control unit or the earphones plugged in? ● Are you trying to play a MiniDisc with data on it instead of a MiniDisc containing music? ● ● ● ● ● When the operation buttons are pressed, the unit does not respond. No sound is heard from the earphones. The unit does not turn on. PROBLEM When the unit has condensation inside, the disc signals cannot be read, and the unit may not function ● Shortly after turning on a heater. properly. ● When the unit is placed in a room where ● If this happens, remove the disc. there is excessive steam or moisture. The condensation should evaporate in ● When the unit is moved from a cool approximately 1 hour. The unit will then place to a warm place. function properly. Many potential “problems” can be resolved by the owner without calling a service technician. If something seems to be wrong with this product, check the following before calling your authorised SHARP dealer or service centre. In the following cases, condensation may form inside the unit. ■ Moisture condensation TROUBLESHOOTING For MiniDiscs on which repeated recording and editing were performed, some sounds may be skipped whilst cueing and reviewing. If there are scratches or dust on a MiniDisc, the track numbers following that track will be increased by one. When recorded tracks are played back using the cue and review operations, some sounds may be skipped. A track number can be created in the middle of a track. For MiniDiscs on which repeated recording and editing operations were performed, the COMBINE function may not work. Two tracks may not be combined in editing. The total of the recorded time and time remaining on a disc may not add up to the maximum possible recording time. When the remaining recording time of a disc is displayed, short tracks less than 12 seconds long may not be included in the total. Even if several short tracks are erased, the remaining recording time may not show an increase. 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. If there are scratches on a disc, the unit will automatically avoid recording in those areas. The recording time will be reduced. Even if the number of tracks and the recording time have not reached the limit, “DISC FULL” may be displayed. Even if the maximum recording time of a MiniDisc has not been reached, “DISC FULL” or “TOC FULL” may be displayed. When the number of tracks used reaches the limit, regardless of the remaining recording time, further recording will be impossible. (Maximum number of tracks: 255) If a MiniDisc has been recorded or edited repeatedly or if a MiniDisc has scratches on it, it may not be possible to record the maximum number of tracks on it. MiniDiscs are recorded using a different system than is used for cassette tapes or DAT recordings. Therefore, the following conditions may be encountered, depending on how the disc has been recorded or edited. These are due to system limitations, and should be considered normal. MINIDISC SYSTEM LIMITATIONS MD-MT821/W –7– ( ● A large portion of the disc has been damaged. ● There is no space left for recording character information (track names, disc names, etc.). ● The track has been protected from being erased. ● A large portion of the disc has been damaged. ● There is an error in the recorded signal. ● A disc which contains data other than music was played. ● There is an error in the signal from the disc. ● Since a track number is currently being located or written to, the unit cannot accept your command. ● You have come to the conclusion that the unit is out of order. ● The temperature is too high. ● The MD is write protected. ● You tried to record without loading an MD. ● A playback-only MD was loaded and the REC button was pressed when the power was off. ● The disc is damaged. ● The EJECT lever was moved during recording or editing. ● A disc has not been loaded. ● You tried to record on a playback- only disc. ● Improper power is being supplied. ● The unit is in the hold mode. ● The disc is out of recording space. ● Poor connection of the digital cable. ● Recording cannot be performed correctly due to vibration or shock in the unit. ● Editing is impossible. ● The disc is scratched. ● No copy can be made because of the SCMS copyright system. ● A track cannot be edited. ● Nothing is recorded. ): Error messages seen on the remote control. ?

Besides, the one with “Fusible” is a fuse type. • Capacitor: To indicate the unit of capacitor, a symbol P is used: this symbol P means micro-micro-farad and the unit of the capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/withstand voltage” is used. (CH), (TH), (RH), (UJ): Temperature compensation (ML): Mylar type B (G) (3) E (S) 1 • The indicated voltage in each section is the one measured by Digital Multimeter between such a section and the chassis with no signal given. • Parts marked with “ ”( ) are important for maintaining the safety of the set. Be sure to replace these parts with specified ones for maintaining the safety and performance of the set. DESCRIPTION REF.
