Precaution to be taken when replacing and servicing the Laser Pickup.
The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class I Requirements.
However, the following precautions must be observed during servicing to protect your eyes against exposure to the laser beam.
(1) When the cabinet has been removed, the power is turned on without a compact disc, and the Pickup is on a position
outer than the lead-in position, the Laser will light for several seconds to detect a disc. Do not look into the Pickup Lens.
(2) The Laser Power Output of the Pickup inside the unit and replacement service parts have already been adjusted prior
to shipping.
(3) No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup.
(4) Under no circumstances look directly into the Pickup Lens at any time.
(5) CAUTION - Use of controls or adjustments, or performance of procedures other than those specified herein may result
in hazardous radiation exposure.

AC adaptor other than those specified.
● The charging time will vary, depending
on the condition of the battery.
● When the battery is charged for the first
time or is charged after not being used
for a long period, the operating time may
be shorter than normal.The battery life
will recover with normal use i.e. charg-
ing and discharging.
● T o av oid shortening the service life of the
battery only recharge the battery after it
has been completely discharged.
RECORDING USING THE OPTICAL DIGITAL CABLE
This is the method used for recording digi-
tal signals from CDs or MDs exactly as they
are stored on the original. Compared to re-
cordings made from analogue inputs, digi-
tal recordings have extremely high-quality
sound.
■ Synchro recording
1
Connect the external equipment.
2
Insert a recordable MiniDisc, and then
press the REC button.
3
Put the equipment connected to this unit
into the playback stand-by mode.
4
Press the ENTER/SYNC button.
5
Start the playback on the equipment
connected to this unit.
■ Manual recording
1
Place the unit in the recording stand-by
mode. (Perform steps 1 - 3 in the “Syn-
chro recording” section.)
2
Press the button, and then start
playback on the equipment connected
to this unit.
● When recording from digital inputs, it is
not necessary to adjust the recording
level.
Notes:
● This unit incorporates a sampling rate
converter.
When this unit is connected to digital
equipment such as CS/BS tuners or DAT
tape recorders that use a different sam-
pling frequency (32 kHz or 48 kHz), re-
cordings 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).

CONVENIENT OPERATION OF THE UNIT
< How to read the battery indicator >
● When the battery is completely discharged,
the battery indicator will flash. Recharge the
battery or replace the alkaline battery with
a new one.
● When the battery has run completely out,
“BATT EMPTY” will appear. Then, the
power will be disconnected automatically.
Notes:
● If you use the battery which you stopped
charging halfway, “
” may appear . It
does not mean that the battery is com-
pletely charged.
● When using the unit with an alkaline bat-
tery or a rechargeable battery, the battery
indicator will not correctly display the remain-
ing capacity for approximately 10 seconds
after the power has been turned on.
● 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 performed.
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).
Battery indicator
Since the battery level is very low, you
cannot start recording or editing.

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.
Many potential “problems” can be resolved by the owner without calling a service techni-
cian.
If something seems to be wrong with this product, check the following before calling your
authorised SHARP dealer or service centre.
■ 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
socket.
2. Remove the battery.
3. Leave the unit completely unpowered for
approximately 30 seconds.
4. Plug the AC adaptor back into the AC
socket and retry the operation.
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 immediately and contact an
authorised SHARP service centre.
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 earphones 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 battery exhausted?
● Is the unit being subjected to excessive vibration?
● Has the track number or character information been
written on the disc yet?
● Is the unit in the recording or editing mode?
● Is the MiniDisc protected against accidental erasure?
● Is the unit connected properly to the other equipment?
● Is the AC adaptor unplugged or did a power failure oc-
cur whilst recording or editing?
● Is the unit in the hold mode?
● Is an optical signal being output from the external equip-
ment?
Read the operation manual for the external equipment.
No sound is heard from
the earphones.
When the operation but-
tons are pressed, the
unit does not respond.
Some sounds are
skipped.
The MiniDisc cannot be
ejected.
Recording and editing
are impossible.

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 whilst 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.

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
• 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.
