                          RF EXPOSURE EVALUATION

1. PRODUCT INFORMATION


   Product Description      TRULY WIRE-FREE EARBUDS


      Model Name            IAEBT209


         FCC ID             2AHI6NIAEBT209


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

 According to the follow transmitter output power(Pt)formula:
 Pt=(E x d)2/(30 x gt)
 Pt=transmitter output power in watts
 gt=numeric gain of the transmitting antenna (unitess)
 E=electric field strength in V/m
 d=measurement distance in meters (m)

 Pt=--6.769dBm=0.21mW

 The result for RF exposure evaluation
 SAR=(0.21mW /5mm) .[√2.48(GHz)]= 0.066<3.0 for 1-g SAR

4. CONCLUSION

 The SAR evaluation is not required.
