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 +41°F (+5°C) and +113°F (+45°C).

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 +140°F (+60°C). For maximum battery

capacity, use the battery at room temperature.

• Turn off your mobile phone before removing the battery.
