RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description TRUE WIRELESS NOISE CANCELING HEADPHONE Model Name ALLY PLUS FCC ID 2ATS9-1297 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 BLE: Pt=3.356dBm=2.17mW The value of the Maximum output power Pt is referred to the test report of the CFR47 §15.247. The result for RF exposure evaluation SAR=(2.17mW /5mm) .[√2.44(GHz)]= 0.68<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. BR/EDR: Pt=4.186dBm=2.62mW The value of the Maximum output power Pt is referred to the test report of the CFR47 §15.247. The result for RF exposure evaluation SAR=(2.62mW /5mm) .[√2.48(GHz)]= 0.80<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. 4. CONCLUSION The SAR evaluation is not required.
