Power Supply
Connect the AC power adapter only to designated power sources as
marked on the product. Make sure the cord is positioned so that it will
not be subjected to damage or stress. To reduce risk of electric
shock, unplug the unit from any power source before attempting to
clean it. The AC power adapter must not be used outdoors or in damp
areas. Never alter the cord or plug. If the plug will not fit into the outlet,
have a proper outlet installed by a qualified electrician.
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.
