FCC ID: 2A8M4S08 RF Exposure evaluation 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 Worse case is as below: For BLE: [2440MHz: -4.77dBm(0.333 mW) output power] (0.333 mW /5mm) ·[√2.440 (GHz)]= 0.104 <3.0 for 1-g SAR For 13.56MHz: EIRP = dBuV/m - 95.2 where: Field strength =69.08 dBuV/m @3m EIRP= 69.08 – 95.2=-26.12dBm(0.002mW) So (0.002mW/5mm) x √0.013 GHz =0.000002 <3 For BLE+13.56MHz: 0.104/3 + 0.000002/3=0.034667<1 Then SAR evaluation is not required
