SAR tests are conducted using standard operating positions accepted by the FCC with the device transmitting at its highest certified power level in all tested frequency bands, although the SAR is determined at the highest certified power level, the actual SAR level of the device while operating can be well below the maximum value. Before a new model phone is available for sale to the public, it must be tested and certified to the FCC that it does not exceed the exposure limit established by the FCC, tests for each phone are performed in positions and locations as required by the FCC. For body-worn operation, this device has been tested and meets the FCC RF exposure when used with an accessory designated for this product or when used with an accessory that contains no metal.
To maintain compliance with the FCC RF exposure guideline, hold the transmitter and antenna at least 1.0 centimetres from your face and speak in a normal voice, with the antenna pointed up and away from the face.
