FCC ID : 2BGKD-BM500SRM Page 1 of 1 Maximum Permissible Exposure RF Exposure Limit According to KDB 447498D01 v06: The 1g and 10g 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)] ꞏ[√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 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 is applied to determine SAR test exclusion. Device category : Portable device Transmitting mode : Single transmitting Max. transmitting frequency : 2 480 MHz Min. test separation distance : 5 mm Max. Antenna Gain : 1.6 dBi Max. Average power : 1.49 dBm Max. power with turn-up tolerance : 2 dBm 1.59 mW Maximum Permissible Exposure For this device: 1.0 mW[maximum average output power]/5 mm[minimum separation distance] x √2.48 GHz = 0.6 Note. The calculation result was rounded to one decimal place for comparison. Test Result : This is less than 3.0 for 1-g SAR. SAR evaluation for general population exposure conditions by measurement or numerical simulation is not required.
