PRODUCT INFORMATION

| Model Name | TAAKYB100042338 |
| FCC ID | 2AOKB-Y2640 |
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
CALCULATION
BR
Pt=-6.749dBm=0.21mW
The value of the Maximum output power Pt is referred to in the test report of
the CFR47 §15.247.
The result for RF exposure evaluation SAR=(0.21mW /5mm).[√2.402GHz)]=0.07<3.0
for 1-g SAR and ≤ 7.5 for 10-g extremity SAR.
CONCLUSION
The SAR evaluation is not required.
