MiniDisc System Limitations

Troubleshooting

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 authorized SHARP dealer or service center.

The unit does not turn on.

No sound is heard from the headphones.

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.

PROBLEM 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?

●

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?

●

Is the unit in the hold mode?

●

Is the battery exhausted?

●

Is the remote control unit plug or the headphones 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 while recording or editing?

●

Is the unit in the hold mode?

●

Is an optical signal being output from the stereo system? Read the operation manual for the stereo system.

The unit may have the following symptoms while recording or editing. The unit is not malfunctioning.

MD-SR60

SYMPTOM

“DISC FULL” or “TOC FULL” appears even though the MiniDisc still has recording time left.

The remaining recording time does not increase even though you erased tracks.

The total of the recorded time and the remaining time does not match the maximum recordable time.

Combine function does not work.

Sound skips in fast reverse/forward.

A track number is created in the middle of a track.

LIMITATIONS

More than 255 tracks (maximum) cannot be recorded regardless of the recording time. If the MiniDisc is recorded or edited repeatedly or if it has scratches (recording skips scratched parts), you may not be able to record the maximum tracks above.

The unit does not count non-recorded portions that last 12 or fewer seconds to display the remaining recording time. The time may not increase even if you erase short tracks.

One cluster (approximately 2 seconds) is the minimum unit for recording. For example, a 3-second track uses 2 clusters (approximately 4 seconds). Therefore, the actual recordable time may be shorter than the displayed time.

A MiniDisc on which recording and editing are repeated may not allow the combine function.

One track is divided and recorded in separate places on a repeatedly recorded or edited MiniDisc. Sound may skip.

A track number may be created if there are scratches or dust on the MiniDisc.

NOTES ON SCHEMATIC DIAGRAM

• Resistor: To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resistor. 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
