CALCULATION RESULTS 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: The maximum conducted power is TX B MODE _2462 MHz. Tune up Average Power Distance Frequency (MHz) Average Power Result Limit (mW) (mm) (dBm) 2462 MHz 13 19.953 5 6.261 7.5 CONCLUSION No SAR evaluation required since transmitter power is below FCC threshold.
