RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description Stereo Wireless Headphones Test Model BMI-985BT-ASST Series Model DELCWBH, DG-985BT-ASST, DG-985BT-XXX, VTY-985BT-ASST FCC ID 2AANZ985BT 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 =2.202dBm=1.66mW 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=(1.66mW /5mm) .[√2.480GHz)]=0.52<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. 4. CONCLUSION The SAR evaluation is not required.
