On the rechargeable battery

•When the battery life of a fully charged rechargeable battery becomes about half the normal life, the battery needs to be replaced with a new one. Consult your nearest Sony dealer. (You must not replace the battery by yourself.)

•CAUTION: The battery used in this device may present a fire or chemical burn hazard if mistreated. Do not disassemble, heat above 100 ºC (212 ºF) or incinerate. Use of another battery may present a risk of fire or explosion.

•Dispose of used battery according to the regulation of recycling or waste.

•Keep away from children.

•Do not disassemble and do not dispose of the battery in fire.

On charging

•The charging time will vary according to the condition under which the battery is used.

•Because of the battery characteristics, the capacity of the rechargeable battery may be smaller than normal when it is used for the first time or after a long period of disuse. In this case, charge and discharge the battery several times. The normal battery life will be restored.

On the speaker cradle

Do not place coins or other metallic objects on the cradle. If the terminal on the cradle accidentally comes into contact with a metallic object, it may short-circuit and begin to heat up.

On the headphones

•If the supplied headphones cause any skin trouble, immediately stop using them and consult a doctor.

•Sound will leak from the supplied headphones if you turn up the volume too high. Keep the volume at a moderate level so that you do not disturb other people around you and you can hear when you are being called. Keep this in mind especially in noisy places where one tends to turn up the volume.

On adjusting the volume

Do not turn up the volume while listening to a section with very low level inputs or no audio signals. If you do, the speakers may be damaged when a peak level section is played.

Road safety

Do not use headphones 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 headsets at high volume while walking, especially at pedestrian crossings. You should exercise extreme caution or discontinue use in potentially hazardous situations.

Preventing hearing damage

Avoid using headphones 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.

Consideration for others

Keep the volume at a moderate level. This will allow you to hear outside sounds and to be considerate to the people around you.
