193Health and Safety Information192Health and SafetyInformationExposure to Radio-FrequencyEnergy (SAR Information)This phone meets European Union (EU)requirements concerning exposure to radiowaves.Your mobile phone is a radio transmitter andreceiver. It is designed and manufactured, so asnot to exceed the limits for exposure to radio-frequency (RF) energy, as recommended by theEU Council. These limits are part ofcomprehensive guidelines and establishpermitted levels of RF energy for the generalpopulation. The guidelines were developed byindependent scientific organisations through theperiodic and thorough evaluation of scientificstudies. The limits include a substantial safetymargin designed to ensure the safety of allpersons, regardless of age and health.The exposure standard for mobile phonesemploys a unit of measurement known as SAR(Specific Absorption Rate). The SAR limitrecommended by the EU Council is 2.0W/kg.** The SAR limit for mobile phones used by the public is 2.0watts/kilogram (W/kg) averaged over ten grams of body tissue. Thelimit incorporates a substantial margin of safety to give additionalprotection for the public and to account for any variations inmeasurements. The SAR values may vary depending on nationalreporting requirements and the network band.SAR tests are conducted using standardoperating positions with the phone transmittingat its highest certified power level in all testedfrequency bands. Although the SAR isdetermined at the highest certified power level,the actual SAR level of the phone whileoperating can be well below the maximum value.This is because the phone is designed to operateat multiple power levels so as to use only thepower required to reach the network. In general,the closer you are to a base station, the lowerthe power output of the phone.Precautions When Using Batteries• Never use any charger or battery that isdamaged in any way.• Use the battery only for its intended purpose.• If you use the phone near the network’s basestation, it uses less power; talk and standbytime are greatly affected by the signal strengthon the cellular network and the parameters setby the network operator.• Battery charging time depends on theremaining battery charge, the type of batteryand the charger used. The battery can becharged and discharged hundreds of times, butit will gradually wear out. When the operationtime (talk time and standby time) is noticeablyshorter than normal, it is time to buy a newbattery.• If left unused, a fully charged battery willdischarge itself over time.
