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 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.

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.

MINIDISC SYSTEM LIMITATIONS

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.

Open the rechargeable battery com-

partment cover.

Insert the rechargeable battery.

Insert the side with the arrow first.

Close the rechargeable battery com-

partment cover.

Plug the AC adaptor into the AC

socket, and then insert the plug on the

AC adaptor lead into the DC IN 5V

socket.

Press the /:OFF button twice to begin

charging.

“ ” will appear, and the battery will

begin charging.

Battery charging will be complete in 2.5

hours. When the charging is com-

plete, “ ” will go out.

POWER SOURCE

Notes:

After charging has been completed, 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 AC adaptor is removed from the

main unit or from the AC socket whilst

charging, “ ” will not disappear for

about 1 minute. This is normal.

Do not force open the rechargeable

battery cover too wide.

Do not fit the separately available bat-

tery case when charging the internal

battery.

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

adaptor, a separately available battery case (AD-M70BC), and a separately available car

adaptor (AD-CA20X).

MD-MS701W/MS702

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 run completely

out, “BATT EMPTY” (main unit) and “Lo

BATT” (remote control unit) will appear.

Then, the power will be disconnected

automatically.

Notes:

When the AC adaptor included with this

unit or a separately 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 batteries are used at the same

time, the rechargeable battery is used first,

and then the alkaline batteries. 

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 alka-

line batteries.

CONVENIENT OPERATION OF THE UNIT

RECORDING USING A SEPARATELY 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).

*Meaning of values

• Temperature reference = Value to be predicted to be measured by the microcomputer at reference temperature (+23.6oC)

• Temperature correction = Value to convert to measurement value at reference temperature (+23.6¯C) *Determining the temperature correction value

• Temperature detection characteristics formula Ambient temperature (oC) = (-2.876 x TEMP input AD value) + 463 Hence, TEMP input AD value = (463 - Ambient temperature)/2.876

• The reference temperature (+23.6oC) is taken as a reference. (it is taken as '0'). Whenever the input AD value changes by '1', temperature is determined. For temperature correction, the input AD value is +/- inverted.
