[(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 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 test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm, and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm according to 4.1 f) is applied to determine SAR test exclusion. 1.3 Calculation Method Tx frequency range: 433.92MHz Min. test separation distance: 5mm Max. Field Strength:76.45dBuV/m Max Power: -18.85 RF channel transmit frequency: 433.92MHz Result: 0.0017 Limit: 3.0 So the transmitter complies with the RF exposure requirements and the SAR is not required. Remark: EIRP (dBm) = E (dBuV/m) - 95.3
