China Certification ICT Co., Ltd (Dongguan) Report No.:2503Z38909E-RF-00A Report Template: RF-FCC-BLE-A/0 Page 59 of 61 5. RF EXPOSURE EVALUATION 5.1 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)] • [√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. 5.2 Measurement Result Frequency (MHz) Conducted Output Power Including Tolerance Distance (mm) Calculated value Threshold (1-g) SAR Test Exclusion (dBm) (mW) 2402-2480 -1 0.79 5 0.2 3 Yes Note: The Maximum Conducted Power including Tune-up Tolerance was declared by manufacturer. Result: Compliant. The stand-alone SAR test is not necessary.
