Portable device
According to §15.247(e)(i) and §1.1307(b)(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 level in excess of the Commission’s guidelines.
According to KDB447498 D01 General RF Exposure Guidance V06
The 1-g SAR 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
When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to
determine SAR test exclusion.
