OPERATION MANUAL
MINIDISC SYSTEM LIMITATIONS
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. Even if the maximum recording time of a MiniDisc has not been reached, "DISC FULL" or "TOC FULL" may be displayed.
POWER SOURCE
This unit can be used with 4 different power sources: a rechargeable battery, an AC adaptor, a separately available battery case (AD-M70BC), and a separately available car adaptor (AD-CA20X).
1
Rechargeable battery power
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.
1 Open
the rechargeable battery compartment cover.
2
Even if the number of tracks and the recording time have not reached the limit, "DISC FULL" may be displayed. Even if several short tracks are erased, the remaining recording time may not show an increase. Two tracks may not be combined in editing.
Mark
2 Insert the rechargeable battery.
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.
Insert the side with the arrow first.
3 Close the rechargeable battery com-
partment cover.
If there are scratches on a disc, the unit will automatically avoid recording in those areas. The recording time will be reduced.

the AC adaptor into the AC socket, and then insert the plug on the AC adaptor lead into the DC IN 5V socket.
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.

charging. " " will appear, and the battery will begin charging. Battery charging will be complete in 2.5 hours. When the charging is complete, " " will go out.
The total of the recorded time and time remaining on a disc may not add up to the maximum possible recording time.
AC 110-240V, 50/60 Hz
Do not force open the rechargeable battery cover too wide. Do not fit the separately available battery case when charging the internal battery.
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. 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 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.
MD-MS701H/MS702H
Notes: After charging has been completed, the AC adaptor may be left connected. (For example, when charging at night) The battery will not be charged whenever the power to the main unit is turned on. If the AC adaptor is removed from the main unit or from the AC socket whilst charging, " " will not disappear for about 1 minute. This is normal.
TROUBLESHOOTING

Digitally recorded MiniDisc
PROBLEM
CAUSE
The unit does not turn on.
Is the AC adaptor disconnected? Is the battery exhausted? Is the unit in the safety mode? Has condensation formed inside the unit? Is the unit being influenced by mechanical shock or by static electricity?
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). Playback
Digital cable
Recording Analogue recording is possible.
No sound is heard from the headphones.
Is the volume set too low? Is the remote control unit or the headphones plugged in? Are you trying to play a MiniDisc with data on it instead of a MiniDisc containing music?
CONVENIENT OPERATION OF THE UNIT
Checking the remaining amount of battery charge
The remaining amount of battery charge is shown by the battery indicator ( ) during operation.
Battery indicator
6
When the battery is completely charged
When the operation buttons are pressed, the unit does not respond.
Is the unit in the safety mode? Is the battery exhausted? Is the remote control unit plug or the headphone plug inserted firmly?
Some sounds are skipped.
Is the battery exhausted? Is the unit being subjected to excessive vibration?
The MiniDisc cannot be ejected.
Has the track number or character information been written on the disc yet? Is the unit in the recording or editing mode?
When the battery is completely discharged, the whole battery indicator will flash. Recharge the battery or replace the alkaline batteries with new ones. 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. Notes:
Recording and editing are impossible.
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 safety mode?
< How to read the battery indicator >
Charging is needed.
If trouble occurs
4. Plug the AC adaptor back into the AC socket and retry the operation.
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.
When the battery needs charging, it is impossible to start recording or editing.
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 batteries are used at the same time, the rechargeable battery is used first, and then the alkaline batteries. 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 batteries.
