Precautions
On batteries
•
Do not carry the dry batteries with coins or other metallic objects.
It can generate heat if the positive and negative terminals of the
batteries are accidentally contacted by a metallic object.
• When you are not going to use your Walkman for a long time,
remove the batteries to prevent damage from battery leakage
and corrosion.
On handling
• 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 leave it in a car with its
windows closed.
•We do not recommend the use of tape longer than 90 minutes.
They are very thin and tend to be stretched easily. This may
cause malfunction of the unit or sound deterioration.
• 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 up for a few minutes before you start
using again.
• Keep personal credit cards using magnetic coding or spring-
wound watches, etc., away from the unit to prevent possible
damage from the magnet used in the speaker.
On headphones/earphones
Road safety
Do not use headphones/earphones while driving, cycling, or
operating any motorized vehicle. It may create a traffic hazard
and is illegal in some areas. It can also be potentially dangerous
to play your headphones/earphones at high volume while
walking, especially at pedestrian crossings.
You should exercise extreme caution or discontinue use in
potentially hazardous situations.
Preventing hearing damage
Do not use headphones/earphones at high volume. Hearing
experts advise against continuous, loud and extended play. If you
experience a ringing in your ears, reduce volume or discontinue
use.
Caring for others
Keep the volume to a moderate level. This will allow you to hear
outside sounds and to be considerate to the people around you.
On maintenance
• Clean the tape head and tape path, using a cotton swab and
commercially available cleaning solvent after every 10 hours of
use.
•To clean the exterior, use a soft cloth slightly moistened in
water. Do not use alcohol, benzine or thinner.
• Clean the headphones/earphones and microphone plugs
periodically.
Troubleshooting
No sound comes out from the speakers.
•Set SPEAKER to ON.
Cannot playback.
•Press OFF to turn off the radio.
The playback speed is too fast/slow.
The playback sound is distorted.
•Set REC TIME at the same position as when the tape
was recorded.
•Replace both batteries with new ones.
Cannot press z REC down.
•If the tab of the tape is broken off, cover the tab hole
with adhesive tape.
The volume cannot be turned up.
•Set AVLS to NORM.
The display and operation are not normal.
•Remove the batteries for 2 minutes or more, and then
insert them again. If this does not solve the problem,
remove the batteries and leave the unit without
batteries for 10 minutes or more, and then insert them
again. In either case, preset the stations again, since the
preset stations are erased from the memory.
