FCC ID: 2BK3WLS1476155FA According to KDB 447498 D01 General RF Exposure Guidance v06, section 4.3.1 At 100 MHz to 6 GHz and for test separation distances ≤ 50 mm, the SAR test exclusion threshold is determined according to the following [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] x [√f(GHz)] ≤ 3.0 1. SAR test exclusion threshold Frequency: 433.92 MHz (min. separation distances = 5 mm) SAR test exclusion thresholds (5 mm) = 3 x 5 / (√ 0.43392) = 22.77 mW Max. Tune-up Tolerance (mW) SAR Test Exclusion Thresholds (5mm) (mW) 1 22.77 Calculation Value: 1 (mW) / 5 (mm) x √ 0.43392 = 0.132 So, Calculation value ≤ 3.0 Remark: -Based on field strength 57.43 dBuV/m at 3m transmit power(eirp) of the device was calculated as 0.0002 mW using free space formula. -Max. conducted power 0.0002 mW is closet 1 mW, so 1 mW was calculated. -When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. 2. Conclusion: No SAR is required.
