Note: PK Output power= conducted power. Conducted power see the test report HK2010093032-E Gantenna gain=0dBi 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 0.0001mW/cm² which is< 1.0mW/cm², RF Exposure testing is not required. -------The End-------
