FCC ID: 2A36Z-WTWASV2 Page 1 of 1 Report No.: CTL2308022011-WF RF Exposure Letter 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 BT pt=3.17dBm=2.07mW at 2402MHz So (2.07mW/5mm)x √2.402GHz =0.6432<3 BLE pt=2.43dBm=1.75mWat2402MHz So (1.75mW/5mm)x√2.402GHz =0.5424<3 Then SAR evaluation is not required
