ume level: VOL 20)

Continuous recording:

Approx. 7 hours (fully charged, anal-

ogue input, volume level: VOL 0)

How to determine the remaining

battery time:

As the battery charge is reduced, the bars

in the indicator will go out one by one.

When the battery is almost completely ex-

hausted, the whole battery indicator will

flash.

At this point you should recharge the bat-

tery.

When the battery has run completely out,

“BATT EMPTY” will be displayed, and the

power will be disconnected automatically.

When the AC adaptor is used, the bat-

tery indicator will light up in the fully

charged condition.

Note:

If the battery indicator is flashing, it will be

impossible to start recording or editing.

Notes about the

rechargeable battery

A rechargeable lithium-ion battery is

the only kind that can be used.

Even if the battery supplied with the

unit is not used, you should charge it at

least once every three months because

of the special quality of this battery.

The rechargeable battery can be

charged approximately 300 times.

Do not use any battery other than that

specified. Use of other batteries may

cause malfunctions.

When the operating time is reduced to

about half the normal amount of time,

even after a full charge is performed,

replace the battery with a new one.

When charging or when using the re-

chargeable battery, use it within an am-

bient temperature range of 5 C to

35°

MD-MS200W/MD-MS200/MD-MS200H

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

prevented by the SCMS (Serial Copy

Management 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

product may not function properly.

If this happens, remove the disc. The

condensation should evaporate in ap-

proximately 1 hour. The unit will then

function properly.

If trouble occurs

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 socket and contact an authorised

Sharp service centre.

Note:

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 trouble occurs, proceed as follows:

1. Unplug the AC adaptor from the AC

socket.

2. Remove the rechargeable battery.

3. Leave the unit completely unpowered

for approximately 30 seconds.

4. Reconnect the AC adaptor to the AC

socket and retry the operation.

Playback Digital cable

Analogue recording is

possible.

MINIDISC SYSTEM LIMITATIONS

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)

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 whilst

cueing and reviewing.

A track number can 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.

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.
