FCC ID: X7STTUWHSD According to 447498 D01 General RF Exposure Guidance v05 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation          [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance,     !-" #$%  &  ! -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)/106 d = measurement distance in meters (m) ---3m So pt = (EXd)2/30 x gt Field strength = 91.10dBuV/m @3m Ant gain =2dBi, so Ant numeric gain= 1.58 (91.1/20) SoSo pt={ [10[10(91.10)/106 x 3]2/30x1.58 }x1000 mW = 0.244mW pt={ So (0.244 mW /5mm)x 0.914 = 0.047<3 Then SAR evaluation is not required
