POWER SOURCE

Notes:

● After charging is complete, the AC

adaptor may be left connected. (For ex-

ample, when charging at night)

● The battery will not be charged when-

ever the power to the main unit is

■ Checking the remaining

amount of battery charge

The remaining amount of battery charge is

shown by the battery indicator ( ) dur-

ing operation.

< How to read the battery indicator >

● When the battery is completely dis-

charged, the whole battery indicator will

flash. Recharge the battery or replace

the alkaline batteries with new ones.

● When the battery has completely run

out, “BATT EMPTY” (main unit) and “Lo

BATT” (remote control unit) will appear.

The power will be disconnected auto-

matically.

Notes:

● When the AC adaptor included with this

unit or an optionally available car adap-

tor is used, the battery indicator will not

be shown.

● The number of bars shown in the bat-

tery indicator may increase or de-

crease, 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 bat-

tery being used, the number of bars will

increase when the unit switches to the

alkaline batteries.

CONVENIENT OPERATION FEATURES

When the battery needs charging, it is

impossible to start recording or editing.

RECORDING USING AN OPTIONALLY AVAILABLE DIGITAL

CABLE

There are cases where digital

recording may be impossible.

In the following cases digital recording is

impossible, even if you are using digital

cables.

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 pre-

vented by the SCMS (Serial Copy Man-

agement System).

Moisture condensation

In the following cases, condensation

may form inside the unit.

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.

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.

TROUBLESHOOTING

If trouble occurs

When this product is subjected to strong

external interference (mechanical shock,

excessive static electricity, abnormal sup-

ply 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

outlet.

2. Remove the battery.

3. Leave the unit completely unpowered

for approximately 30 seconds.

4. Plug the AC adaptor back into the AC

outlet and retry the operation.

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 outlet immediately and contact an au-

thorized Sharp service center.

Many potential “problems” can be resolved by the owner without calling a service tech-

nician. If something seems to be wrong with this product, check the following before

calling your authorized SHARP dealer or service center.

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?

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?

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?

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 while recording or editing?

Is the unit in the safety mode?

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: 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.

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.

When the remaining recording time of

a disc is displayed, short tracks less

than 8 seconds long may not be

included in the total.

Two tracks may not be combined in

editing.

For MiniDiscs on which repeated

recording and editing operations were

performed, the COMBINE function

may not work.

The total of the recorded time and

time remaining on a disc may not

add up to the maximum possible

recording time.

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.

For MiniDiscs on which repeated

recording and editing were performed,

some sounds may be skipped while

cueing and reviewing.

While recording, a track number may

be created in the middle of a track.

If there are scratches or dust on a

MiniDisc, the track numbers following

that track will be increased by one.

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.

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

MD-MS702MK

• 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.
