SGS-CSTC Standards Technical Services Co., Ltd. Shanghai Branch Report No.: SHEM190100008102 Page: 6 of 8 4 Test Standards and Limits 4.1 FCC Radiofrequency radiation exposure limits 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)/(min test separation distance)]*[√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 • The result is rounded to one decimal place for comparison • 3.0 and 7.5 are referred to as the numeric thresholds 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. For 2.4G band device, the limit of worse case is Pmax≤3*Dmin)/ f =3*5/ 2.480 =9.525mW

SGS-CSTC Standards Technical Services Co., Ltd. Shanghai Branch Report No.: SHEM190100008102 Page: 7 of 8 4.2 IC Radiofrequency radiation exposure limits According to RSS-102 section 2.5.1, SAR evaluation is required if the separation distance between the user and/or bystander and the antenna and/or radiating element of the device is less than or equal to 20 cm, except when the device operates at or below the applicable output power level (adjusted for tune- up tolerance) for the specified separation distance MHz 5 10 15 20 25 30 35 40 45 50 mm ≤300 71 101 132 162 193 223 254 284 315 345 450 52 70 88 106 123 141 159 177 195 213 835 17 30 42 55 67 80 92 105 117 130 1900 7 10 18 34 60 99 153 225 316 431 mW 2450 4 7 15 30 52 83 123 173 235 309 3500 2 6 16 32 55 86 124 170 225 290 5800 1 6 15 27 41 56 71 85 97 106 Output power level shall be the higher of the maximum conducted or equivalent isotropically radiated power (e.i.r.p.) source-based, time-averaged output power. For controlled use devices where the 8 W/kg for 1 gram of tissue applies, the exemption limits for routine evaluation are multiplied by a factor of 5. For limb-worn devices where the 10 gram value applies, the exemption limits for routine evaluation in Table 1 are multiplied by a factor of 2.5. If the operating frequency of the device is between two frequencies located in Table 1, linear interpolation shall be applied for the applicable separation distance. For test separation distance less than 5 mm, the exemption limits for a separation distance of 5 mm can be applied to determine if a routine evaluation is required. The practical use condition for this device is as a body accessories. So the applicable limit is 10-g extremity SAR For 2.4G band device, the limit is Pmax≤4mW

Shanghai Branch Report No.: SHEM190100008102 Page: 8 of 8 5 Measurement and Calculation 5.1 Maximum transmit power The Power Data is based on the RF Test Report SHEM190100008101. Test Data: Output Power Reading Power Test Frequency (dBm) (mW) Test Mode (MHz) 1M Rate 2M Rate 1M Rate 2M Rate 2402 2.00 1.96 1.58 1.57 BLE 2440 1.88 1.81 1.54 1.52 2480 0.68 0.60 1.17 1.15 5.2 RF Exposure Calculation The Max Conducted Peak Output Power is 1.58mW. The best case gain of the antenna is 2.2dBi. 2.2dBi logarithmic terms convert to numeric result is nearly 1.66 For FCC Max Output Power = 2.62 mW<9.525mW For IC Max Output Power = 2.62 mW＜4mW So the SAR report is not required. --End of the Report--
