See KDB 447498 D01 General RF Exposure Guidance v05, section 4.3.1. 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, 16 where ·f(GHz) is the RF channel transmit frequency in GHz ·Power and distance are rounded to the nearest mW and mm before calculation17 ·The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. Dongguan Nore Testing Center Co., Ltd.

Fox example: 3.08 /5*√2.440=0.962 ≤ 3.0 According to KDB447498 D01 V05, threshold at which no SAR required is ≤3.0 for 1-g SAR, separation distance is 5mm, and no SAR measurement is required. The SAR measurement is not necessary.
