Charging the rechargeable battery

When the rechargeable battery is used for the firsttime or when you use it after a long period of dis-use, be sure to charge it fully.

1 Slide the battery cover as far as it will goto the outside.

2 Lift the battery cover.Do not force the battery cover open too far.

3 Insert the rechargeable battery from the(+) marked side.

Only the rechargeable battery that is suppliedand the battery that is available separately(Part number AD-N70BT) can be charged.

4 Close the battery cover.

5 Plug the AC adaptor into the AC outlet, andthen insert the plug on the other end intothe DC IN 5V jack.

6 Press the :OFF/CHRG (• ) button.“ ” will flash, and battery will begin charging.

When the batterylevel is high

When the batterylevel is very low

Checking the remaining amount ofbattery level

The remaining amount of battery level is shownby the battery indicator ( ) during operation.

When the battery is completely discharged, the battery indicator will flash. Recharge the battery or replace thealkaline battery with a new one.When the battery has run completely out, “BATTEMPTY” will appear. Then, the power will be discon-nected automatically.

Notes:If you use the battery which you stopped charging half-way, “ ” may appear. It does not mean that the bat-tery is completely charged.The battery indicator will not correctly display the remain-ing capacity for approximately 10 seconds after the powerhas been turned on.When the AC adaptor or a separately available car adap-tor is used, the battery indicator will not be shown.The number of bars shown in the battery indicator mayincrease or decrease, depending on the operation be-ing performed. This is normal.

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

MiniDisc System Limitations

SYMPTOM

“DISC FULL” or “TOC FULL” appearseven though the MiniDisc still has re-cording time left.

The remaining recording time does notincrease even though you erased tracks.

The total of the recorded time and theremaining time does not match the maxi-mum recordable time.

Combine function does not work.

Sound skips in fast reverse/forward.

A track number is created in the middleof a track.

LIMITATIONS

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

The unit does not count non-recorded portions that last 12 or fewer secondsto display the remaining recording time. The time may not increase even ifyou 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 displayedtime.

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

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

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

TroubleshootingMany 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 orservice center.

The unit does not turn on.

No sound is heard from the head-phones.

When the operation buttons arepressed, the unit does not respond.

Some sounds are skipped.

The MiniDisc cannot be ejected.

Recording and editing are impossible.

NOTES ON SCHEMATIC DIAGRAM

• Resistor:To differentiate the units of resistors, such symbol as K andM are used: the symbol K means 1000 ohm and the symbolM means 1000 kohm and the resistor without any symbol isohm-type resistor. Besides, the one with “Fusible” is a fusetype.

• Capacitor:To indicate the unit of capacitor, a symbol P is used: thissymbol P means micro-micro-farad and the unit of thecapacitor without such a symbol is microfarad. As to electro-lytic capacitor, the expression “capacitance/withstand volt-age” is used.(CH), (TH), (RH), (UJ): Temperature compensation(ML): Mylar type

• The indicated voltage in each section is the one measuredby Digital Multimeter between such a section and the chas-sis with no signal given.

• Parts marked with “ ” ( ) are important formaintaining the safety of the set. Be sure to replace theseparts with specified ones for maintaining the safety andperformance of the set.
