the preset stations may not be recalled correctly
when you use the unit for the first time, or
when you have left the unit without batteries
for a long time. In these cases, remove the
batteries, and wait until the display disappears.
Then insert batteries and turn the unit on again.
The preset stations will be canceled. Reset these

Poor tape playback quality.
•Clean the headphones/earphones plug.
•Dirty head. Clean the head and tape path with
a cotton swab slightly moistened with cleaning
fluid or alcohol.
The cassette holder cannot be opened.
•Open the buckle and then the rubber cap. Then
you can open the cassette holder. Once the
cassette holder is open, remember to close the
rubber cap to prevent intrusion of water.
Precautions
• Do not drop the unit or give a shock to the unit, or it
may cause a malfunction.
• Do not leave the unit in a location near heat sources,
or in a place subject to direct sunlight, excessive dust
or sand, moisture, rain, mechanical shock, or in a car
with its windows closed.
• Do not wind the headphones/earphones cord around
the unit. The buttons may be kept pressed, causing
unnecessary battery usage.
• The LCD display may become hard to see or slow
down when using the unit at high temperatures
(above 40°C/104°F) or at low temperatures (below
0°C/32°F). At room temperature, the display will
return to its normal operating condition.
• If the unit has not been used for a long time, set it in
the playback mode to warm it up for a few minutes
before inserting a cassette.
• Do not use cassettes longer than 90 minutes except for
long continuous playback.
• For cleaning the case, use a soft cloth slightly
moistened with mild detergent solution. Do not use
alcohol, benzine or thinner.
On water resistance
• Before opening or closing the cassette holder, be sure
to wipe off water, dust or sand on the exterior of the
Walkman. (The Walkman is not water-resistant with
the cassette holder open.)
• Since water in the headphones/earphones jack may
cause rust, cover it with the attached rubber cap when
the headphones/earphones are not in use.
• Since the Walkman is airtight, you may not be able to
open the cassette holder because of sudden change in
air pressure inside the Walkman which happens after
being transported on a plane or moving from a warm
place to a cold place. To open the cassette holder, see
“Troubleshooting”.
• The supplied headphones/earphones are not meant
to be immersed in water or come in continuous
contact with water. If they are accidentally dropped
into water or get wet, dry them with a soft cloth.
Never use an electric hair dryer.
• If the Walkman or the headphones/earphones are
immersed in salt water, be sure to wash them in non-
running fresh water. Never wash them under running
water, and never use soap or detergent.
• Any sand or dust on the rubber packing will prevent
the cassette holder from closing tightly, and water
may leak in. Brush off the dust once in a while.
• We recommend the packing to be changed every year.
Replacement packing is available at an authorized
Sony Service Facility.
If you have any questions or problem concerning your
Walkman, please consult your nearest Sony dealer.
