Product Name：Personal Audio System Model Number: CFD-S70BT FCC ID: AK8CFDS70BT RADIO FRREQUENCY EXPOSURE COMPLIANCE RESULT : Test Standard : FCC KDB Publication 447498 D01 V06 Clause 4.3.1, The 1-g 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 • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below 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 according to 5) in section 4.1 is applied to determine SAR test exclusion. According to the actual measurement, max. power of channel, including tune-up tolerance =1.497mW min. test separation distance= 5mm √f(GHz)=1.57 The test result is 0.470058≤3.0 for 1-g SAR≤ 7.5 for 10-g SAR, hence the EUT is excluded from SAR evaluation according to FCC KDB Publication 447498 D01: General RF Exposure Guidance V06.
