FCC ID: U2BRL039T8S RF Exposure Evaluation According to KDB 447498 and part 2.1093，Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition(s), listed below, is (are) satisfied. For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(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 Here, Max Power (dBm) Maximum tune-up (dbm) Max tune-up (mW) Frequency (MHz) Min. distance(mm) Calc. thresholds limit 7.61 8 6.31 2477.6 5 1.99 3.0 Contains FCC ID: 2AOT2SH-BLEM01, The maximum BLE output power is 0.00073W. 0.73X√2.480 /5 =0.23 The maximum simultaneously transmission is 1.99+0.23=2.22<3.0 S o, it compliance.
