In this case, press the / :OFF button twice to turn the power off. the AC adaptor into the AC socket, and then insert the plug on the AC adaptor lead into the DC IN 5V socket. About 4 seconds later, “ ” will flash, and the battery will begin charging. Battery charging will be complete in 3.0 hours. When the charging is complete, “ ” will go out. 4 Plug partment cover. 3 Close the rechargeable battery com- Insert the side with the arrow first. 2 Insert the rechargeable battery. the rechargeable battery compartment cover. 1 Open When the rechargeable battery is used for the first time or when you want to use it after a long period of disuse, be sure to charge it fully. Rechargeable battery power This unit can be used with 4 different power sources: a rechargeable battery, an AC adaptor, a battery case, and a separately available car adaptor (AD-CA20X). 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 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. Digital cable Digital cable Recording Analogue recording is possible. Playback Digitally recorded MiniDisc CD player, MD player, etc. Playback Recording When using the unit with an alkaline battery or a rechargeable battery, the battery indicator will not display correctly 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, and 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. Notes: 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-MS722/C/W/MS721W OPERATION MANUAL When the unit has condensation inside, the disc signals cannot be read, and the unit may not function properly. If this happens, remove the disc. The condensation should evaporate in approximately 1 hour. The unit will then function properly. –7– 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 battery exhausted? Is the unit being subjected to excessive vibration? Has the track number or character information been written on the disc yet? Is the unit in the recording or editing mode? 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. No sound is heard from the earphones. When the operation buttons are pressed, the unit does not respond. Some sounds are skipped. The MiniDisc cannot be ejected. Recording and editing are impossible. 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 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 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? The unit does not turn on. If trouble occurs 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? PROBLEM 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. 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. In the following cases, condensation may form inside the unit. Moisture condensation TROUBLESHOOTING If there are scratches on a disc, the unit will automatically avoid recording in those areas. The recording time will be reduced. When the remaining recording time of a disc is displayed, short tracks less than 12 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. 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. 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. Even if several short tracks are erased, the remaining recording time may not show an increase. 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 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. When the number of tracks used reaches the limit, regardless of the remaining recording time, further recording will be impossible. (Maximum number of tracks: 254) 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. 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. 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-MS722/C/W/MS721W ( Nothing is recorded. BLANK DISC (BLANK) Can't COPY (Not REC) –8– The disc is out of recording space. A large portion of the disc has been damaged.
