FCC ID: OGGK3QFX126815 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 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, g t = 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 For BT mode Field strength = 90.52dBuV/m @3m Ant gain =0dBi, so Ant numeric gain= 1 So pt={ [10 (90.52/20) /10 6 x 3] 2 /30x1}x1000 mW =0.338mW So (0.338mW /5mm)x √2.480 = 0.106< 3 For BLE mode Field strength = 91.43dBuV/m @3m Ant gain =0dBi, so Ant numeric gain= 1 So pt={ [10 (91.43/20) /10 6 x 3] 2 /30x1}x1000 mW =0.417mW So (0.417mW /5mm)x √2.440 = 0.130<3 Then SAR evaluation is not required
