RF Exposure Test Requirement: FCC 47CFR 15.247(i) Test Date: 2020-12-10 Mode of Operation: Tx mode Test Method: 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. Test Results: The EUT complied with the requirement(s) of this section. EUT meets the requirements of these sections as proven through MPE calculation The MPE calculation for EUT @ 20cm Based on the highest Tolerance Power =1.294 mW Pd = PG/ 4pi*R 2 = (1.294x 1)/12.566* (20) 2 = (1.294)/12.566x 400= 1.294/5026.4 = 0.000257mW/cm 2 where: *Pd = power density in mW/cm2 * G = Antenna numeric gain (1); Log G = g/10 ( g = 0dBi ). *Tolerance Range(-0.5, 0.5)dB * P = Conducted RF power to antenna (1.294mW). * R = Minimum allowable distance.(20 cm) *The power density Pd = 0.000257mW/cm 2 is less than 1 mW/cm 2 (listed MPE limit) *The SAR evaluation is not needed ( this is a desk top device, R> 20 cm ) * The EUT( antenna ) must be 0.2 meters away from the General Population.
