RF EXPOSURE EVALUATION

1. PRODUCT INFORMATION
Product Description Bluetooth Earphone

Model Name BT959, BT959B, BT959W, BT958B, BT958W, BL959B, BL959W

FCC ID 2ACP4LBT959

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= -3.997dBm=0.40mW

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=(0.40mW /5mm) .[√2.480(GHz)]= 0.13<3.0
for 1-g SAR and ≤ 7.5 for 10-g extremity SAR.

4. CONCLUSION
The SAR evaluation is not required.
