RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description ANC TRULY WIRELESS STEREO EARBUDS Model Name N10 Plus FCC ID 2ARGT-N10PLUS 2. EVALUATION METHOD According to 447498 D01 General RF Exposure Guidance v06 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 3. CALCULATION BR/EDR: P t = 6.340dBm=4.31mW The value of the Maximum output power P t is referred to the test report of the CFR47 §15.247. The result for RF exposure evaluation SAR=(4.31mW /5mm) .[√2.480GHz)]=1.35<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. BLE: P t = 4.076dBm=2.56mW The value of the Maximum output power P t is referred to the test report of the CFR47 §15.247. The result for RF exposure evaluation SAR=(2.56mW /5mm) .[√2.480GHz)]= 0.80<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. 4. CONCLUSION The SAR evaluation is not required.
