SAFETY PRECAUTION FOR SERVICE MANUAL
(MD-MT80W/90W ONLY)
Precaution to be taken when replacing and servicing the
Laser Pickup.
Laser Diode Properties
● Material: GaAlAs
● Wavelength: 785 nm
● Pulse time:
Read mode: 0.8 mW Continuous
Write mode:
max 10 mW 0.5S
min cycle 1.5S
Repetition
THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER
POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER
COMPONENT IS CAPABLE OF EMITTING RADIATION
EXCEEDING THE LIMIT FOR CLASS 1. THEREFORE IT IS
IMPORTANT THAT THE FOLLOWING PRECAUTIONS ARE
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.
English:
This product is classified as a CLASS 1 LASER PRODUCT.
German:
Dieses Produkt ist ein Laserprodukt der Klasse 1.
French:
Ce Produit est Classifié comme étant un PRODUCTO
LASER DE CLASSE 1.
Precaution to be taken when replacing and servicing the laser pickup.
The following precautions must be observed during servicing to protect your eyes against exposure to the laser.
Warning of possible eye damage when repairing:
If the AC adaptor or batteries are connected when the top housing (disc cover) of the unit is removed, and the PLAY key is
pressed, the laser will light up during focus access (2-3 seconds). (Fig. 2-1) During the operation, the laser will leak from the
opening between the magnetic head and the mechanical chassis (Fig. 2-2). In order to protect your eyes, you must not look
at the laser during repair. Before repairing be sure to disconnect the AC adaptor and remove the batteries.

"AA" size alkaline battery.
● 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 completely charged.
● The battery indicator will not correctly display the
remaining capacity for approximately 10 seconds after
the power has been turned on.
● When the AC adaptor 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

MiniDisc System Limitations
The unit may have the following symptoms while recording or editing. The unit is not out of order.
SYMPTOM
LIMITATIONS
"DISC FULL" or "TOC FULL" appears
even though the MiniDisc still has recording time left.
More than 255 tracks (maximum) cannot be recorded regardless of
the recording time. If the MiniDisc is recorded or edited repeatedly or
if it has scratches (recording skips scratched parts), you may not be
able to record the maximum tracks above.
The remaining recording time does not
increase even though you erased
tracks.
The unit does not count non-recorded portions that last 12 or fewer
seconds to display the remaining recording time. The time may not
increase even if you erase short tracks.
The total of the recorded time and the
remaining time does not match the maximum recordable time.
One cluster (approximately 2 seconds) is the minimum unit for recording. For example, a 3-second track uses 2 clusters (approximately 4 seconds). Therefore, the actual recordable time may be
shorter than the displayed time.
Combine function does not work.
A MiniDisc on which recording and editing are repeated may not allow the combine function.
Sound skips in fast reverse/forward.
One track is divided and recorded in separate places on a repeatedly
recorded or edited MiniDisc. Sound may skip.
A track number is created in the middle
of a track.
A track number may be created if there are scratches or dust on the
MiniDisc.
Troubleshooting
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 authorised SHARP dealer or service centre.
PROBLEM
The unit does not turn on.
CAUSE
● Is the AC adaptor disconnected?
● Is the battery exhausted?

● Are you trying to play a MiniDisc with data on it instead of a MiniDisc containing music?
When the operation buttons are
pressed, the unit does not respond.
● Is the unit in the hold mode?
Some sounds are skipped.
● Is the battery exhausted?
The MiniDisc cannot be ejected.
● Has the track number or character information been written on the disc yet?
● Is the battery exhausted?
● Is the remote control unit plug or the headphones plug inserted firmly?
● Is the unit being subjected to excessive vibration?
● Is the unit in the recording or editing mode?
Recording and editing are impossible.
● 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 occur whilst recording or editing?
● Is the unit in the hold mode?
● Is an optical signal being output from the stereo system? Read the operation
manual for the stereo system.

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 “

maintaining the safety of the set. Be sure to replace these
parts with specified ones for maintaining the safety and
performance of the set.
