FCC ID: 2A2A5-ALEXSON According to 447498 D01 General RF Exposure Guidance v06 The 1-g and 10-g SAR test exclusion thresholds 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(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where --f(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 eirp = pt x gt = (EXd) 2 /30 where: pt = transmitter output power in watts, gt = numeric gain of the transmitting antenna (unitless), E = electric field strength in V/m, --- 10 ((dBuV/m)/20) /10 6 d = measurement distance in meters (m) ---3m So pt = (EXd) 2 /30 x gt BT EDR: Field strength = 95.46 dBuV/m @3m Ant gain =1.72 dBi, so Ant numeric gain= 1.58 So pt={ [10(95.46/20)/106 x 3]2/30x1.58}x1000 mW = 0.297mW So (0.297mW /5mm)x √ 2.441 = 0.312<3 Then SAR evaluation is not required
