Additional information
Emergency calls
Mobile phones operate using radio signals, which
cannot guarantee connection under all conditions.
Therefore you should never rely solely upon any
mobile phone for essential communications
(e.g. medical emergencies).
Emergency calls may not be possible on all cellular
networks or when certain network services and/or
mobile phone features are in use. Check with your
local service provider.
Battery use and care
We recommend that you fully charge the battery
before you use your mobile phone for the first time.
The battery should only be charged in temperatures
between +5°C (+41°F) and +45°C (+113°F).
A new battery or one that has not been used for
a long time could have reduced capacity the first
few times it is used.
The talk and standby times depend on the actual
transmission conditions when using the mobile
phone. If the mobile phone is used near a base
station, less power is required and talk and standby
times are prolonged.
• Warning! May explode if disposed of in fire.
• Use only Sony Ericsson branded original batteries
and chargers intended for use with your mobile phone.
Other chargers may not charge sufficiently or may
produce excessive heat. Using other batteries and
chargers could be dangerous.
• Do not expose the battery to liquid.
• Do not let the metal contacts on the battery touch
another metal object. This could short-circuit and
damage the battery.
• Do not disassemble or modify the battery.
• Do not expose the battery to extreme
temperatures, never above +60°C
(+140°F). For maximum battery capacity,
use the battery in room temperature.
• Turn off your mobile phone before
removing the battery.
• Keep out of children’s reach.
• Use the battery for the intended
purpose only.
• Do not allow the battery to be put into
the mouth. Battery electrolytes may be
toxic if swallowed.
Disposing of the battery
Please check local regulations for
disposal of batteries or call your local
Sony Ericsson Customer Care Center
for information.
The battery should never be placed in municipal
waste. Use a battery disposal facility if available.
