Reference 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 2. Result 1) According to the output power measurement, and the tune-up statement by manufacturer, the calculated value can obtained. Test Frequency (MHz) Minimum Separation Distance (mm) Max. Output Power (dBm) Output Power with tune up (dBm) Output Power (mW) calculated value exclusion thresholds Bluetooth 2480.00 5.00 8.408.507.082.23 3 BLE 2480.00 5.00 2.122.201.660.52 3 2) .Conclusion: No SAR is required.
