Page 1 of 2 RF Exposure Evaluation Report 1 RF EXPOSURE Product Name Bluetooth Speaker Model No. BT2107, BT2288 FCC ID 2AYL8-BT2107 1.1 LIMITS 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 17 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 Page 2 of 2 1.2 EUT RF EXPOSURE EVALUATION Operational Mode: EDR （8-DPSK worst case） Channel Maximum Peak Conducted Output Power (dBm) Tune up tolerance (dB) Maximum tune-up Power(dB m) Maximum tune-up Power(mW ) Calculated value Exclusion threshold 2402MHz 3.35 ±1 4.35 2.72 0.84 3 2441MHz 3.07 ±1 4.07 2.55 0.80 3 2480MHz 2.16 ±1 3.16 2.07 0.65 3 Conclusion: the calculated value ≤3.0, SAR is exempted.
