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 +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. Additional information 71 This is the Internet version of the user's guide. © Print only for private use.
