Precautions
On rechargeable battery and
charger
• Remove the charger unit from the wall outlet as soon as
possible after the rechargeable battery has been charged.
Overcharging may damage the rechargeable battery.
• The battery charger and the rechargeable battery may become
warm during charging, but this is not a problem.
• Do not tear off the film on the rechargeable battery.
• Use only the supplied battery charger to charge the supplied
rechargeable battery.
• Be sure not to short-circuit the battery. When you carry it with
you, use the supplied carrying case. If you are not using the
case, do not carry the battery with other metallic objects such as
keys rings in your pocket.
• If the rechargeable battery is new or has not been used for a
long time, it may not be charged completely until you use it
several times.
• The nameplate indicating the operating voltage, power
consumption, etc. is located on the bottom exterior of the
battery charger.
On batteries
• Do not charge a dry battery.
• Do not carry the dry or rechargeable 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 do not use the Walkman for a long time, remove the
battery to avoid any damage caused by battery leakage and
subsequent 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 in a car with its windows
closed.

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.
• Do not use cassettes longer than 90 minutes except for long
continuous playback.

mode to warm up for a few minutes before you start using
again.
