Welcome !
Thank you for purchasing the Sony MiniDisc
Player. This unit lets you enjoy a variety of
features using the following controller
accessories:
Optional accessories
Rotary commander RM-X4S
Card remote commander RM-X91
In addition to the MD playback and radio
operations, you can expand your system by
connecting optional CD/MD units*
1
.
When you operate this unit or a connected
optional CD unit with the CD TEXT function,
the CD TEXT information will appear in the
display when you play a CD TEXT disc*
2
.
*
1
You can connect MD changers, CD changers, MD
players, or CD players.
*
2
A CD TEXT disc is an audio CD that includes
information such as the disc name, artist name
and track names.
This information is recorded on the disc.
Precautions
• If your car was parked in direct sunlight
resulting in a considerable rise in
temperature inside the car, allow the unit to
cool off before operating it.
• If no power is being supplied to the unit,
check the connections first. If everything is in
order, check the fuse.
•If your car is equipped with a power
antenna, it will extend automatically while
the unit is operating.
•Do not use the Custom file feature while
driving, or perform any other function which
could divert your attention from the road.
If you have any questions or problems
concerning your unit that are not covered in
this manual, please consult your nearest Sony
dealer.
Moisture Condensation
On a rainy day or in a very damp area,
moisture may condense on the lenses inside
the unit. Should this occur, the unit will not
operate properly. In such a case, remove the
disc and wait for about an hour until the
moisture has evaporated.
To maintain high quality sound
If you have drink holders near your audio
equipment, be careful not to splash juice or
other soft drinks onto the unit and MD. Sugary
residues on the unit or MD may contaminate
the lenses inside the unit, reduce the sound
quality, or prevent sound reproduction
altogether.

Notes on MDs
Since the disc itself is housed in a cartridge,
free from accidental contact with your fingers
and dust, MDs can withstand a certain degree
of the rough handling. However, dirt or dust
on the surface of the cartridge or a warped
cartridge may cause a malfunction. Observe
the following for best results.
Never touch the surface of the disc itself by
deliberately opening the shutter on the
cartridge.
When you eject the MD, the shutter may be
open. In such a case, close the shutter
immediately.
Do not expose the MD to direct sunlight or
heat sources such as hot air-ducts. Do not leave
it in a car parked in direct sunlight where there
can a considerable rise in temperature.
Make sure the MD is not left on the dashboard
or rear tray of a car, etc. where the temperature
can also be excessive.
Notes on attaching labels
Be sure to attach labels on cartridges correctly,
as failing to do so may cause the MD to
become stuck in the unit.
•Attach the label in a suitable position.
•Remove old labels before putting new ones
on.
•Replace labels that are beginning to peel
away from the MD.
Cleaning
Wipe the surface of the cartridge from time to
time with a soft dry cloth.
