When the minimum test separation distance is <5 mm, a distance of 5 mm according to 5) in section 4.1 is applied to determine SAR test exclusion. Measurement Result The max conducted power including tune-up tolerance is -1 dBm (0.79 mW). [(max. power of channel, mW)/(min. test separation distance, mm)][√f(GHz)] =0.79/5*(√2.480) = 0.3< 3.0 Result: Compliant.
