RF EXPOSURE EVALUATION

1. PRODUCT INFORMATION

Product Description Wireless Speaker

Model Name BTSP41

FCC ID 2AO23-BTSP41

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

Pt= 6.118dBm=4.09mW

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=(4.09mW /5mm) .[√2.448(GHz)]= 1.28<3.0
for 1-g SAR and ≤ 7.5 for 10-g extremity SAR.

4. CONCLUSION

The SAR evaluation is not required.
