FCC ID: 2BFZA-DCU150 Label location

FCC ID: 2BFZA-DCU150 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. MPE Calculation Method E (V/m) ＝ d GP**30 Power Density: Pd (W/m²) ＝ 377 2 E E ＝ Electric field (V/m) P ＝ Average RF output power (W) G ＝ EUT Antenna numeric gain (numeric) d ＝ Separation distance between radiator and human body (m) The formula can be changed to Pd ＝ 2 *377 **30 D GP From the EUT RF output power, the minimum mobile separation distance, d=0.005m, as well as the gain of the used antenna, the RF power density can be obtained.
