OPERATION MANUAL

■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.

1Open the rechargeable battery com-

partment cover.

2Insert the rechargeable battery.

●Insert the side with the arrow first.

3Close the rechargeable battery com-

partment cover.

4Plug the AC adaptor into the AC outlet,

and then insert the plug on the AC

adaptor cord into the DC IN 5V jack.

5Press the ■:OFF button to begin charg-

ing.

●The POWER indicator will flash, and

the battery will begin charging.

●Battery charging will be complete in 3.5

hours. When the battery is fully

charged, the POWER indicator will go

out.

POWER SOURCE

Notes:

●After charging is complete, the AC

adaptor may be left connected.

(For example, when charging at night)

●The battery will not be charged when-

ever the power to the main unit is

turned on.

●If the operation in step 5 is performed

without inserting the rechargeable bat-

tery, the POWER indicator will flash for

5 seconds. This is normal.

●Do not force open the rechargeable

battery cover too far.

●Do not attach the optionally available

battery case when charging the internal

battery.

This unit can be used with 4 different power sources: a rechargeable battery, an AC

adaptor, an optionally available battery case (AD-S30BC), and an optionally available car

adaptor (AD-CA20X).

■ Checking the remaining

amount of battery charge

The remaining amount of battery charge is

shown by the battery indicator ( ) on

the remote control display during oper-

ation.

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 battery with a new one.

●When the battery has completely run

out, “Lo BATT” will appear in the dis-

play. Then, the power will be discon-

nected automatically.

Notes:

●

When the AC adaptor included with this

unit or an optionally 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, de-

pending on the operation being per-

formed. This is normal.

●

When the rechargeable battery and the

alkaline battery are used at the same time,

the rechargeable battery is used first, and

then the alkaline battery.

Since the battery indicator shows the re-

maining amount of the particular battery

being used, the number of bars will in-

crease when the unit switches to the al-

kaline battery.

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 centre.

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

cian. 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?

Has condensation formed inside the unit?

Is the unit being influenced by mechanical shock or by

static electricity?

Some sounds are

skipped. Is the battery exhausted?

Is the unit being subjected to excessive vibration?

TROUBLESHOOTING

When an error message is displayed on the display, proceed as follows:

Display Meaning Remedy

BLANK Nothing is recorded. Replace the disc with a

recorded disc.

E-DISC

The disc is damaged or

the music information is

not written properly on the

disc.

Replace the disc.

E-SYS The unit is malfunctioning

and will require service. For service, contact your

local Sharp authorized

servicer.

E-TEMP The temperature is too

high. Turn off the power, and

wait for a while.

E-TOC

E-UTOC The disc is damagad. Replace the disc.

Lo BATT

The battery has run down. Charge the rechargeable

battery or replace the

alkaline battery (or use

the AC adaptor for power).

No DISC A disc has not been

loaded. Load a disc.

POWER? Improper power is being

supplied. Use one of the specified

power sources.

?DISC There is an error in the

signal from the disc. Replace the disc.

■ Volume setting

Reduce the volume before starting to play. MiniDiscs,

compared to ordinary cassette tapes, have very little

noise. If the volume is adjusted according to your

usual expectations of noise, you may damage your

hearing due to the high volume.

■

Ajuste del volumen

Reduzca el volumen antes de iniciar la reproducción.

Los mínidiscos, en comparación con las cintas de

casete normales, tienen muy poco ruido. Si se ajusta

el volumen de acuerdo con el ruido que puede esper-

arse normalmente, podría dañarse los oídos debido

al alto volumen.

■ Important

●Do not wear your headphones when you are cross-

ing streets or near traffic.

●Do not use your headphones while driving a motor

vehicle, it may create a dangerous traffic hazard

and may be illegal. Remember to obey all of the

safety rules in your area.

●Do not play the unit at a high volume. Hearing

experts advise against extended play at high vol-

ume levels.

●If you experience ringing in your ears, reduce the

volume or discontinue use.

■

Importante

●

No se ponga auriculares cuando atraviese calles ni

cuando esté cerca del tráfico.

●

No emplee los auriculares mientras conduce un

vehículo, porque puede crear situaciones peligro-

sas en el tráfico y puede ser ilegal. Recuerde que

debe respetar las reglas de seguridad de su zona.

●

No reproduzca sonido en el aparato a altos niveles

de volumen. Los expertos dicen que es perjudicial

la reproducción continuada a altos niveles de vol-

umen.

●

Si nota timbres en los oídos, reduzca el volumen o

no utilice el aparato.

DISASSEMBLY

Caution on Disassembly

Follow the below-mentioned notes when disassembling

the unit and reassembling it, to keep it safe and ensure

excellent performance:

1. Take the battery and minidisc out of the unit.

2. When disassembling the machine, be sure to withdraw

the power plug from the socket in advance.

3. When disassemble the parts, remove the nylon band or

wire holder as necessary.

To assemble after repair, be sure to arrange the wires as

they were.

If a screw of different length is fitted to the MD mecha-

nism (the screw of the part to be fitted to the MD

mechanism chassis), it may contact the optical pickup,

resulting in malfunction.

4. When repairing, pay due attention to electrostatic charges

of IC.

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 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 measured

by Digital Multimeter between such a section and the chas-

sis 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.

• The wiring diagram and the PWB drawing may be changed

to refect improvements in the design without prior notice.

They may differ a little the unit you have.
