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 can 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 Ericsson or 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.
