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).
POWER SOURCE
OPERATION MANUAL
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.
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 8 seconds long may not be
included in the total.
For MiniDiscs on which repeated
recording and editing operations were
performed, 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 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.
For MiniDiscs on which repeated
recording and editing were performed,
some sounds may be skipped whilst
cueing and reviewing.
If there are scratches or dust on a
MiniDisc, the track numbers following
that track will be increased by one.
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
operations, some sounds may be
skipped.
A track number can be created in
the middle of a track.
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
MD-MS701H/MS702H
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.

Playback
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, 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 battery
being used, the number of bars will increase when the unit switches to the alkaline batteries.
Notes:
When the battery is completely discharged, 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.
CONVENIENT OPERATION OF THE UNIT
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).
In the following cases digital recording is
impossible, even if you are using digital
cables.
There are cases where digital
recording may be impossible.

2. Temperature reference setting method
[1] Measurement, calculation and setting procedure
(1) Set the TEST mode.
• Set TEST 1, 0 = '01', and turn on power (or set PLAY ON in standby state).
(2) Start the EEPROM mode 'Temp' menu.
• In the TEST mode STOP state, press the keys as follows: BASS, SKIP-DOWN x 2 times, PLAY, SKIP-DOWN x 4 times,
and PLAY in this order.
• 'TM$$%%' is displayed. ($$= Temperature code, %% = Temperature reference)
(3) Once press SKIP-UP, and determine the displayed microcomputer TEMP input AD value.
• 'TPin##' is displayed. (## = TEMP input AD value)
(4) At the ambient temperature, determine the temperature corrected value from the temperature measurement value
correction table.
(5) Determine the temperature reference, using the following formula.
• Temperature reference = Microcomputer TEMP input AD value + Temperature corrected value
• An example: Environmental temperature is 22°C and set voltage is 1.25V.

*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.

NOTES ON SCHEMATIC DIAGRAM
(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 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.
• 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.
