FCC ID:2A86Y-TG-182 RF EXPOSURE EVALUATION METHOD SAR Test Exclusion Thresholds for 100 MHz – 6 GHz and ≤ 50 mm Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. 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 The result is rounded to one decimal place for comparison 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 is applied to determine SAR test exclusion. FCC ID:2A86Y-TG-182 For BT mode -- The max. field strength of fundamental frequency is 93.81 dBuv/m. EIRP[dBm] = E[dBμV/m] - 95.2 = 93.81 - 95.2 = -1.39dBm, conducted power = EIRP - ANT gain = -1.39 - (1.2) = -2.59 dBm. The max. tune-up level is -1.59dBm(0.693mw), MPE=0.693 mw / 5mm * √(2.402GHz) = 0.214 < 7.5 (extremity sar), sar exempt. Conclusion: No SAR is required.
