RF EXPOSURE EVALUATION

1. PRODUCT INFORMATION
Product Description Wireless Bluetooth Earbuds

Model Name BTWB66, GBB-6, GBB6, BTWB67, BTWB-67, BTWB-66

FCC ID 2AO23-BTWB88

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= -0.785dBm=0.83mW

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=(0.83mW /5mm) .[√2.402(GHz)]= 0.26<3.0 for
1-g SAR and ≤ 7.5 for 10-g extremity SAR.

4. CONCLUSION
The SAR evaluation is not required.
