According to KDB 447498 D01 General RF Exposure Guidance 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 1. f(GHz) is the RF channel transmit frequency in GHz. 2. Power and distance are rounded to the nearest mW and mm before calculation. 3. The result is rounded to one decimal place for comparison. 4. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test Exclusion. Measurement Result For worst case: Mode Frequency (MHz) Max tune-up conducted power # (dBm) Max tune-up conducted power # (mW) Distance (mm) Calculated value Threshold (1-g SAR) SAR Test Exclusion BT 2402-2480 4.0 2.51 5 0.8 3.0 Yes Result: Compliant
