FCC ID: 2A3LS-PAK06 RF Exposure evaluation According to 447498 D01 and 47CRF part 2.1093. 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 Here, For BLE Frequency (MHz) Max power (dBm) Max power (mW) Min. distance (mm) Calculation Value Threshold Value 2440 0.90 1.23 5 0.38 3.0 For 433.92MHz 1.
