BEFORE RETURNING THE AUDIO PRODUCT
(Fire & Shock Hazard)
Before returning the audio product to the user, perform the following
safety checks.
1. Inspect all lead dress to make certain that leads are not pinched or
that hardware is not lodged between the chassis and other metal
parts in the audio product.
2.Inspectall protectivedevicessuch asinsulatingmaterials, cabinet,
terminal board, adjustment and compartment covers or shields,
mechanical insulators etc.
3. To be sure that no shock hazard exists, check for leakage current
in the following manner.
* Plug the AC line cord directly into a 120 volt AC outlet.
*Using twoclip leads,connect a1.5k ohm,10 wattresistorparalleled
by a 0.15µF capacitor in series with all exposed metal cabinet parts
and a known earth ground, such as conduit or electrical ground
connected to earth ground.
* Use a VTVM or VOM with 1000 ohm per volt, or higher, sensitivity
to measure the AC voltage drop across the resistor (See diagram).
* Connect the resistor connection to all exposed metal parts having a
return path to the chassis (antenna, metal cabinet, screw heads,
knobs and control shafts, escutcheon, etc.) and measure the AC
voltage drop across the resistor.
All check must be repeated with the AC line cord plug connection
reversed.
Any reading of 0.3 volt RMS (this corresponds to 0.2 milliamp. AC.)
or more is excessive and indicates a potential shock hazard which
must be corrected before returning the audio product to the owner.

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 ex-
cessive 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, and open the disc
holder. The condensation should evaporate in approxi-
mately 1 hour. The unit will then function properly.
If a problem occurs
If this product is subjected to strong external inter-
ference (mechanical shock, excessive static electricity,
abnormal supply voltage due to lightning, etc.) or if it
is operated incorrectly, it may malfunction or the display
may not function correctly. If such a problem occurs,
do the following:
Unplug the AC power cord from the AC outlet.
Wait about 20 - 30 seconds and then plug the AC power
lead back into the AC outlet.
Press the reset button on the back of the unit.
1
2
3
When the reset button is pressed, all of the settings in
memory will be erased.
If strange sounds, smells or smoke come out of the unit
or if a foreign object falls into the unit, turn off the power,
unplug the AC power cord from the AC outlet, immedi-
ately. Contact your nearest authorized Sharp servicer.
If a power failure occurs during recording
If the AC power plug is disconnected from the AC outlet
or a power failure occurs during recording (before the
TOC information has been recorded on the disc), the
audio portion being recorded at that time will be erased.
When a recording is being added to a MiniDisc which
already has a recording on it, if the TOC is not updated
before the power failure, the added recording will be
erased.
If a power failure occurs or the AC power cord is dis-
connected for about 10 minutes, when power is restored,
TOC will be written on the disc.

SYMPTOM POSSIBLE CAUSE REMEDY
(Continued)
If a problem occurs
If this unit functions abnormally during operation, first check the following items. If the unit continues to function abnormally,
or if an abnormality appears other than listed below, turn off the player's power and disconnect the AC power plug, then
consult your SHARP dealer or service personnel.
General
SYMPTOM POSSIBLE CAUSE REMEDY
The clock is wrong. Did a power failure occur? Try setting it again.
When a button is pressed, the unit
does not respond. Turn the power off and on again, and
then retry the operation.
Radios make unusual noise or the pic-
ture on the TV screen is distorted. When a radio or TV which uses an
indoor antenna is placed near the
unit, the picture on the TV screen may
be distorted or the radio may not func-
tion properly.
It is recommended that you use an
outdoor antenna.
Audio
A recording cannot be made. Is the MiniDisc protected against ac-
cidental erasure? Slide the accidental erase prevention
tab back to its original position.
Did you try to make recording on a
playback-only MiniDisc? Replace it with a recordable disc.
Can you see the “TOC FULL” mess-
age in the display? Put in another recordable disc with
recording space on it.
Even though a disc has been loaded,
“no disc” or “Error” is displayed. Is the disc scratched?
Is the unit located near excessive vi-
brations?
Replace the disc.
Place the unit on a firm, level surface
free from vibration.
Playback stops in the middle of a
track, or playback is not performed
properly.
Is the unit located near excessive vi-
brations? Place the unit on a firm, level surface
free from vibration.
Playback sounds are skipped. Has condensation formed inside the
unit? Remove the disc and leave the power
turned on. The unit should function
properly in about 1 hour.
Remote control
SYMPTOM POSSIBLE CAUSE REMEDY
The remote control does not function
or does not operate properly. The batteries (polarity) are not inserted
properly. Insert properly.
The batteries inside the remote control
are dead. Replace the batteries.
The remote control is operated from
an incorrect distance or angle. Operate it within a range of 8" (0.2 m)
to 20' (6 m) and within an angle of 15
o
to either side of center.
No disc has been loaded. Load a disc.
The power cannot be turned on from
the remote control. Is the AC power cord plugged in? Connect the AC power cord.
(Continued)
When an error message is displayed, proceed as follows:
Error messages Meaning Remedy
BLANK MD Nothing is recorded.
(Neither music nor a disc name have been
recorded on this MD.)
Replace the disc with a recorded disc.
Can't COPY You tried to record from a disc which you are
not allowed to copy. Replace it with another disc which you can
copy from (regular CD).
Can't EDIT A track cannot be edited. Change the stop position of the track and then
try editing it.
Can't REC Recording cannot be performed correctly due to
vibration. Move the unit away from the source of vibration.
DEFECT Since this disc has scratches on it, the
recording operation was skipped. Replace the disc with another recordable disc.

DISASSEMBLY
Caution on Disassembly
Follow the below-mentioned notes when disassembling
the unit and reassembling it, to keep it safe and ensure
excellent performance:
1. Take the minidisc out of the unit.
2. When disassembling the machine, be sure to withdraw
the power plug from the socket in advance.
3. When disassemble the parts, remove the nylon band or
wire holder as necessary.
Toassemble afterrepair, be sure to arrangethe wiresas
they were.
If a screw of different length is fitted to the MD mecha-
nism (the screw of the part to be fitted to the MD
mechanism chassis), it may contact the optical pickup,
resulting in malfunction.
