If the battery cover is lifted without being slid all the way out, it may break. ■ Synchro recording 1 This is the method used for recording digital signals from CDs or MDs exactly as they are stored on the original. Compared to recordings made from analogue inputs, digital recordings have extremely high-quality sound. Digital cable Recording Recording Analogue recording is possible. Digital cable Notes: ● This unit incorporates a sampling rate converter. When this unit is connected to digital equipment such as CS/BS tuners or DAT tape recorders that use a different sampling frequency (32 kHz or 48 kHz), recordings can still be made. (The sampling frequency of this unit is 44.1 kHz.) ● When making a digital recording from a portable CD player (if the player has a sound skip prevention function and this function is turned on) the optical output will drop out and digital recording will not be possible. Be sure to turn the sound skip prevention function off. Playback MD player Digitally recorded MiniDisc CD player, MD player, etc. Playback 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). There are cases where digital recording may be impossible. In the following cases digital recording is impossible, even if you are using digital cables. RECORDING USING THE OPTICAL DIGITAL CABLE 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 You can power this unit with an AC adaptor or a commercially available alkaline battery (LR6, “AA” size). You can also power this unit with a rechargeable battery (AD-N70BT) or car adaptor (AD-CA20X) which are available separately. MD-SR50H/50W/60E/60W OPERATION MANUAL When the battery level is very low –6– Notes: ● If you use the battery which you stopped charging halfway, “ ” may appear. It does not mean that the battery is completely charged. ● When using the unit with an alkaline battery or a rechargeable battery, the battery indicator will not correctly display the remaining capacity for approximately 10 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 battery is completely discharged, the 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” will appear. Then, the power will be disconnected automatically. Since the battery level is very low, you cannot start recording or editing. When the battery level is high < How to read the battery indicator > To avoid accidental operation of the unit, use the hold function. The remaining amount of battery level is shown by the battery indicator ( ) during operation. Battery indicator Cancel Cancel Hold Cancel Hold Main unit If the hold function is active whilst the power is turned off, the power cannot be turned on by mistake and the battery will not be accidentally drained. Can be operated from either the remote control unit or the main unit. Cancel Hold Can only be operated from the main unit. Can only be operated from the remote control unit. Hold Cannot be operated from either the remote control unit or the main unit. Remote control unit For MD-SR60E/SR60W Only ● To cancel the hold mode, move the HOLD switch away from the safety position (the opposite direction of the arrow). For MD-SR60E/SR60W Only ● When the unit is in the hold mode, pressing the buttons will have no affect. Move the HOLD switch to the safety position (direction indicated by the arrow). ■ To prevent the unit from being operated by mistake ■ Checking the remaining amount of battery level CONVENIENT OPERATION OF THE UNIT 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. 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? 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. 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. ● Has the track number or character information been written on the disc yet? ● Is the unit in the recording or editing mode? ● Is the battery exhausted? ● Is the unit being subjected to excessive vibration? Some sounds are skipped. The MiniDisc cannot be ejected. ● Is the unit in the hold mode? ● Is the battery exhausted? ● Is the volume set too low? ● Is 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 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 MD-SR50H/50W/60E/60W 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. 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. If there are scratches on a disc, the unit will automatically avoid recording in those areas. The recording time will be reduced. Even if several short tracks are erased, the remaining recording time may not show an increase. 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.

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 TOP VIEW • 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.
