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 battery indicator may increase or decrease,
depending on the operation being performed. This is normal.
● When the battery is completely discharged, the battery indicator will flash.
Recharge the battery or replace the alkaline batteries with new ones.
● When the battery has run completely out,
“BATT EMPTY” will appear. Then, the
power will be disconnected automatically.
Since the battery level is very low, you
cannot start recording or editing.

PROBLEM
Many potential “problems” can be resolved by the owner without calling a service technician.
If something seems to be wrong with this product, check the following before calling your
authorized SHARP dealer or service center.
MD-MT15/15C/15H/15W/161E/18H
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 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 while cueing and
reviewing.
If there are scratches or dust on a
MiniDisc, the track numbers following that
track will be increased by one.
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.
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.
Even if the number of tracks and
the recording time have not
reached the limit, “DISC FULL”
may be displayed.
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: 255)
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.
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.

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.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
