FCC ID: 2BFCM-X1PRO RF exposure evaluation §2.1093 Radiofrequency radiation exposure evaluation: Portable Devices. 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 level in excess of the commission’s guidance. The 1-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, where f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation When the minimum test separation distance is < 5 mm, a distance of 5 mm according is applied to determine SAR test exclusion. The result is rounded to one decimal place for comparison GFSK Modulation Frequency (MHz) Max.
