RF Exposure Info

China Certification ICT Co., Ltd (Dongguan) Report No.: CR230952546-00B Page 57 of 61 5. RF EXPOSURE EVALUATION 5.1 FCC SAR test exclusion 5.1.1 Applicable Standard According to§15.247(i) and §1.1310, systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. According to KDB447498 D01 General RF Exposure Guidance v06: 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)] ꞏ [√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 • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below 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 according to 5) in section 4.1 is applied to determine SAR test exclusion. 5.1.2 Measurement Result The max conducted power including tune-up tolerance is 3.0dBm (2.00 mW). [(max. power of channel, mW)/(min. test separation distance, mm)][√f(GHz)] =2.0/5*(√2.480) = 0.6< 3.0 Result: Compliant. The stand-alone SAR evaluation is not necessary.
