FCC ID: FSUGKZHN 1. Applicable Standards FCC Part 2(Section 2.1093) FCC KD B447498 D01 General RF Exposure Guidance v06 2. Exposure Evaluation of Portable or Mobile Devices Human exposure to RF emissions from portable devices (47 CFR §2.1093), as defined by the FCC, must be evaluated with respect to the FCC-adopted limits for SAR. Evaluation of mobile devices, as defined by the FCC, may also be performed with respect to SAR limits, but in such cases it is usually simpler and more cost-effective to evaluate compliance with respect to field strength or power density limits. For certain devices that are designed to be used in both mobile and portable configurations similar to those described in 47 CFR §2.1091(d)(4), such as certain desktop phones and wireless modem modules, compliance for mobile configurations is also satisfied when the same device is evaluated for SAR compliance in portable configurations. SAR Test Exclusion Thresholds for 100 MHz – 6 GHz and ≤ 50 mm 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. EST Technology Co., Ltd Report No. ESTE-R1909097 Page 2 of 3

FCC ID: FSUGKZHN 3. Evaluation Results For 2.4GHz Ant gain=-0dBi ;so Ant numeric gain=1 Field strength = 74.89 dBuV/m @3m So Pt={ [10^(74.89/20)/10^6 x3]^2/(30x1) }x1000 mW = 0.009mW So ( 0.009 mW/5mm)x √2.480 GHz = 0.003 < 3 Note: 1. [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] * [√f(GHz)] < 3.0 2. SAR Test Exclusion Thresholds is 3.0 for separation distance 5mm. Therefore, SAR test is not required. End of Test Report EST Technology Co., Ltd Report No. ESTE-R1909097 Page 3 of 3
