MPE ESTIMATION FCC ID: 2BON5-433-A19 1. Limit for Portable Equipment Exposure Frequency 1-g SAR 100MHz-6GHz 3.0 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 2. Estimation Result Frequency Reading result(dBμV/m) PK Output Power (dBm) Output Power(mW) Test Separation Distance (mm) Measurement Result 1-g SAR ASK 433.92 MHz 72.31 -22.89 0.005 5 0.0007 3.0 Note: PK Output Power (dBm)= Reading result(dBμV/m)-95.2 Reading result see the test report UNIA26031822ER-61.
