RF Exposure Requirements

Product Description: Fitness Wristband
Model No.: HW702A, HW702, HW703, HW704, HW705
FCC ID: 2ACN7HW702A

According to the KDB 447498 D01 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,16 where
- f(GHz) is the RF channel transmit frequency in GHz
- Power and distance are rounded to the nearest mW and mm before calculation
- The result is rounded to one decimal place for comparison

Bluetooth(BLE)

Conducted Max. Power Distance Frequency
Result Limit
Power (dBm) (mW) (mm) (GHz)
-0.456 0.90 5 2.480 0.28 3
[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance,
mm)] · [√f(GHz)]: 0.90/5*√2.480=0.28

The exclusion thresholds is less than 3, therefore, the RF exposure evaluation is not required.
