FCC ID: IYFDIDJ1001 RF Exposure evaluation According to 447498 D01 General RF Exposure Guidance v05 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances İ50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] g[Ĝf(GHz)] İ3.0 for 1-g SAR and İ7.5 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 Worse case is as below: [2474.872MHz 15.98dBm(39.63mW) output power] (39.63mW /30mm) g[Ĝ2.474872(GHz)]= 2.078 <7.5 for 10-g SAR Then SAR evaluation is not required for the evaluation distance, please refer to the photo below. 30mm 52mm (worse case )
