Conducted power see the test report HK2012153927-E. Gantenna gain=-1dBi when the minimum test separation distance is >20 cm, a distance of 20 cm is applied to determine RF Exposure test exclusion. The test exclusion threshold is 0.01113mW/cm² which is< 1.0mW/cm², RF Exposure testing is not required. -------The End-------
