According to §15.247(i) and §1.1307b(1), systems operating under the provisions of this section
shall be operated in a manner that ensures that the public is not exposed to radio frequency
energy levels in excess of the Commission’s guidelines. 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.

Fox example: 0.47*√2.402=0.1457 ≤ 3.0
According to KDB447498 D01 V06, threshold at which no SAR required is ≤3.0 for 1-g
SAR, separation distance is 5mm, and no simultaneous SAR measurement is required.
