FCC ID: 2AMH2—BHO28A RF EXPOSURE EVALUATION METHOD SAR Test Exclusion Thresholds for 100 MHz ~ 6 GHz and < 50 mm Approximate SAR Test Exclusion Power Thresholds xt Selected Frequencies and Test Separation Distances are illustrated in the following Table. e s 10 is 20 2s mm 150 so m us 153 194 300 27 ss a uo 137 450 22 as a7 so u> a3s i6 3 40 se 2 Em G 5 a7 C 7o 1500 12 x 37 m SATest Exclusion 1900 u 22 33 5t Threshold(raW) 2450 10 19 Eo as 3600 s 16 2 5 20 5200 7 in 20 26 a 5400 6 i6 19 26 » seoo 6 12 19 as a _| The 1—g and 10— SAR test exclusion thrasholds for 100 MHz to 6 GHz at test separation distances < 50 mm are determined by: [{max. power of channel, including tune—up tolerance, mW)/(min. test separation distance, mm}] + [/f(GHe)] < 3.0 for 1—g SAR and < 7.5 for 10—4 extremity SAR.where 1(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is < 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion
