RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description ANC Truly Wireless Stereo Earbuds Model Name N10 Pro FCC ID 2ARGT-N10PRO 2. EVALUATION METHOD 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 ≤ 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 =5.789dBm=3.79mW 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=(3.79mW /5mm) .[√2.402GHz)]=1.17<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. BLE: P t = 1.051dBm=1.27mW 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=(1.27mW /5mm) .[√2.402GHz)]= 0.39<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. 4. CONCLUSION The SAR evaluation is not required.
