Product Description: ACTIVE NOISE CANCELLING WIRELESS STEREO HEADPHONES
Model No.: TT-BH047
FCC ID: 2AFDGTT-BH047
According to the KDB 447498 D01 v06 section 4.3.1, for 100 MHz to 6 GHz and test separation
distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the
following:
[(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 calculation17
- The result is rounded to one decimal place for comparison
Calculation Result:
Tx frequency range: 2402-2480MHz
Min. test separation distance: 5mm
Maximum Conducted Output Power: 3.416dBm
Tune-Up output power: 4dBm
RF channel transmit frequency: 2402MHz
Result: 0.8
Limit: 3.0
The exclusion thresholds is 0.8 < 3, so the transmitter complies with the RF exposure
requirements and the SAR is not required.
