154 Safety Precautions and Conditions of Usethe phone transmitting at its highest certified powerlevel in all tested frequency bands. Although the SARis determined at the highest certified power level, theactual SAR level of the phone while operating can bewell below the maximum value. This is because thephone is designed to operate at multiple power levels soas to use only the power required to reach the network.In general, the closer you are to a wireless base stationantenna, the lower the power output.Before a phone model is available for sale to the public,it must be tested and certified to the FCC that it does notexceed the limit established by the government-adoptedrequirement for safe exposure. The tests are performedin positions and locations (e.g., at the ear and worn onthe body) as required by the FCC for each model. Thehighest SAR value for this model phone when tested foruse at the ear is 0.996 W/kg and when worn on thebody, as described in this user guide, is 0.800 W/kg.Body-worn Operation; This device was tested fortypical body-worn operations with the back of thephone kept 1.5 cm from the body. To maintaincompliance with FCC RF exposure requirements, useaccessories that maintain a 1.5 cm separation distancebetween the user’s body and the back of the phone. Theuse of belt-clips, holsters and similar accessories shouldnot contain metallic components in its assembly.The use of accessories that do not satisfy theserequirements may not comply with FCC RF exposurerequirements, and should be avoided. While there maybe differences between the SAR levels of variousphones and at various positions, they all meet thegovernment requirement for safe exposure.The FCC has granted an Equipment Authorization forthis model phone with all reported SAR levelsevaluated as in compliance with the FCC RF emissionguidelines. SAR information on this model phone is onfile with the FCC and can be found under the DisplayGrant section of http://www.fcc.gov/oet/fccid aftersearching on FCC ID APYHRO00047.Additional information on Specific Absorption Rates(SAR) can be found on the CellularTelecommunications & Internet Association (CTIA)web-site at http://www.phonefacts.net.* In the United States and Canada, the SAR limit formobile phones used by the public is 1.6 watts/kg (W/kg) averaged over one gram of tissue. The standardincorporates a substantial margin of safety to giveadditional protection for the public and to account forany variations in measurements.
