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.
