OPERATION MANUAL

RECORDING USING THE OPTICAL DIGITAL CABLE

This is the method used for recording digi-

tal signals from CDs exactly as they are

stored on the original. Compared to record-

ings made from analog inputs, digital re-

cordings have extremely high-quality

sound.

1

Connect the external equipment.

2

Start recording.

Synchro recording:

Before starting a synchro recording,

perform the following steps on the

equipment connected to this unit.

(1) First, put it in the playback mode.

(2) Next, put it in the pause mode.

(3) Finally, position it at the beginning

of the track you want to record.

(1) Insert a recordable MiniDisc, and

then press the REC button.

(2) Press the ENTER/SYNC button.

(3) Start the playback on the equipment

connected to this unit.

Manual recording:

(1) Insert a recordable MiniDisc, and

then press the REC button.

● When recording from digital inputs,it

is not necessary to adjust the record-

ing level.

Notes:

● This unit incorporates a sampling rate

converter.

When this unit is connected to digital

equipment such as a DSS tuners or a

DAT tape recorder that use a different

sampling frequency (32 kHz or 48 kHz),

recordings can still be made. (The sam-

pling 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.

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 re-

corded 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).

cian.

If something seems to be wrong with this product, check the following before calling your

authorized SHARP dealer or service center.

■ 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 out-

let.

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.

outlet immediately and contact an autho-

rized SHARP service center.

PROBLEM CAUSE

The unit does not turn

on.

● 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 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 unit being subjected to excessive vibration?

TROUBLESHOOTING

■ 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.

If the hold function is active while the power

is turned off, the power cannot be turned

on by mistake and the battery will not be

accidentally drained.

CONVENIENT OPERATION OF THE UNIT

< How to read the battery indicator >

● When the battery is completely dis-

charged, the battery indicator will flash.

Recharge the battery or replace the al-

kaline batteries with new ones.

● When the battery has run completely out,

“BATT EMPTY” will appear. Then, the

power will be disconnected automatically.

Notes:

● When using the unit with alkaline bat-

teries or a rechargeable battery, the bat-

tery indicator will not correctly display

the remaining capacity for approximately

10 seconds after the power has been

turned on.

● When an AC adaptor or a car adaptor is

used, the battery indicator will not be

shown.

● The number of bars shown in the bat-

tery indicator may increase or decrease,

depending on the operation being per-

formed. This is normal.

■ To prevent the unit from being

operated by mistake

To avoid accidental operation of the unit,

use the hold function.

Move the HOLD switch to the safety posi-

tion (direction indicated by the arrow).

● When the unit is in the hold mode, press-

ing the buttons will have no affect.

● To cancel the hold mode, move the

HOLD switch away from the safety po-

sition (the opposite direction of the ar-

row).

PROTECTED

When the number of tracks used reaches

the limit, regardless of the remaining re-

cording time, further recording will be

impossible.

(Maximum number of tracks: 255)

If a MiniDisc has been recorded or ed-

ited repeatedly or if a MiniDisc has

scratches on it, it may not be possible to

record the maximum number of tracks on

it.

If there are scratches on a disc, the unit

will automatically avoid recording in those

areas. The recording time will be reduced.

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 record-

ing and editing operations were per-

formed, 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 re-

cording may be less than the remaining time

displayed.

If there are scratches on discs, those sec-

tions will be automatically avoided (no record-

ing will be placed in those sections). There-

fore, the recording time will be reduced.

For MiniDiscs on which repeated record-

ing and editing were performed, some

sounds may be skipped while cueing and

reviewing.

If there are scratches or dust on a

MiniDisc, the track numbers following that

track will be increased by one.

MINIDISC SYSTEM LIMITATIONS

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.

Even if the maximum recording

time of a MiniDisc has not been

reached, “DISC FULL” or “TOC

FULL” may be displayed.

Even if the number of tracks and

the recording time have not

reached the limit, “DISC FULL”

may be displayed.

Even if several short tracks are

erased, the remaining recording

time may not show an increase.

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 op-

erations, some sounds may be

skipped.

A track number can be created in

the middle of a track.

DISASSEMBLY

Cares before disassembling

When assembling the machine after disassembling or repair, observe the following requirements so as to ensure safety and performance.

1. Remove the batteries from the machine, and take out the mini-disc.

2. When assembling after repair, be sure to restore the initial location of wires. Since the screws are small, incorrect fixing may result in malfunction.

3. When repairing, pay utmost attention to static electricity of IC.

NOTES ON SCHEMA TIC 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
