DEKRA Testing and Certification, S.A.U. Parque Tecnológico de Andalucía, c/ Severo Ochoa nº 2 · 29590 Campanillas · Málaga · España C.I.F. A29 507 456 FCC SAR test exclusion considerations As stated by the FCC (47 CFR §2.1093), human exposure to RF emissions from portable devices, which are defined as transmitting devices to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user, must be evaluated with respect to the FCC-adopted limits for SAR. According to FCC OET KDB 447498 D01 General RF Exposure Guidance: Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition is satisfied. - For distances ≤ 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. Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table: MHz 5 10 15 20 25 30 35 40 45 50 mm 150 39 77 116 155 194 232 271 310 349 387 300 27 55 82 110 137 164 192 219 246 274 450 22 45 67 89 112 134 157 179 201 224 835 16 33 49 66 82 98 115 131 148 164 SAR Test 900 16 32 47 63 79 95 111 126 142 158 1500 12 24 37 49 61 73 86 98 110 122 Exclusion 1900 11 22 33 44 54 65 76 87 98 109 Threshold 2450 10 19 29 38 48 57 67 77 86 96 (mW) 3600 8 16 24 32 40 47 55 63 71 79 5200 7 13 20 26 33 39 46 53 59 66 5400 6 13 19 26 32 39 45 52 58 65 5800 6 12 19 25 31 37 44 50 56 62 Table 3: SAR Test Exclusion Thresholds for 100 MHz – 6 GHz and ≤ 50 mm Report No: (NIE) 57186RAN.002A1 Page 8 of 23 2019-08-29

Multiple frequencies assessment When multiple sources are introduced into an environment, it becomes necessary to address the sources interdependently, since each source will contribute some percentage of the maximum exposure toward the total exposure. The sum of the ratios of the exposure from each source to the corresponding maximum exposure for the frequency of each source must be evaluated. The exposure complies with the maximum permissible exposure if the sum of the ratios is less than unity: n Exp i  <1 i 1 Limit i Where Expi is the measured/calculated exposure value of each source; Limiti is the applicable limit of each source. The device under evaluation is able to transmit simultaneously using SRD 5 MHz and Bluetooth LE / Proprietary 2.4 GHz, therefore the worst case multiple frequencies calculation will be as follow: 0.042 0.125 + = 0.026 + 0.128 = 0.154 < 1 Limit 1.6 0.978 Report No: (NIE) 57186RAN.002A1 Page 13 of 23 2019-08-29

Using FCC KDB 447498 D01 General RF Exposure Guidance (see page 11 of this document), the estimated 1-g SAR value is 0.042 W/kg. According to “RSS-102, Table 3: SAR Limits for Devices Used by the General Public”, the 1-g SAR limit for localized limbs is 1.6 W/kg. Report No: (NIE) 57186RAN.002A1 Page 17 of 23 2019-08-29

A29 507 456 2. 5MHz SRD Nerve Stimulation evaluation According to RSS-102 Issue 5, Nerve Stimulation exposure limits shall be evaluated for transmission into the frequency range from 0.003 to 10 MHz. Supplementary Procedure SPR-002, Issue 1, for Radio Standards Specification RSS-102 sets out the general test methods to be followed when carrying out an assessment to the nerve stimulation exposure requirements of RSS-102 Issue 5. Measurements have been performed installing the device at the edge of an 80 cm tall and non-metallic constructed table, placing the measurement probe at a compliance distance of 0 cm between the probe edge and each device side that can be used to install the device, as specified into Supplementary Procedure SPR- 002, “Annex E – E.1.1. Passively Used Table-Top Devices”, using the equipment listed in the “Used Instrumentation” paragraph of this document, and following the measurement method shown in paragraph 6.6.1.1 of “Supplementary Procedure for Assessing Compliance with RSS-102 Nerve Stimulation Exposure Limits SPR-002”: Top Front Left Right Back Bottom Figure 14: Measurement setup The maximum measured values for this transmitting technology are listed in the following tables: Frequency H-Field measurements [A/m] Max Limit % Verdict (MHz) Top Bottom Left Right Front Back [A/m] [A/m] Limit 5.0 0.010 0.000 0.010 0.000 0.125 0.075 0.125 90 0.14 Pass Table 15: H-field measurement values Frequency E-Field measurements [V/m] Max Limit % Verdict (MHz) Top Bottom Left Right Front Back [V/m] [V/m] Limit 5.0 7,19 3,02 2,40 2,94 5,33 9,59 9.59 83.0 11.55 Pass Table 16: E-field measurements values All H-Field and E-Field values are in compliance to values shown into “Table 4: RF Field Strength Limits for Devices Used by the General Public” for the frequency range used by the device.

Multiple frequencies assessment When multiple sources are introduced into an environment, it becomes necessary to address the sources interdependently, since each source will contribute some percentage of the maximum exposure toward the total exposure. The sum of the ratios of the exposure from each source to the corresponding maximum exposure for the frequency of each source must be evaluated. The exposure complies with the maximum permissible exposure if the sum of the ratios is less than unity: n Exp i  <1 i 1 Limit i Where Expi is the measured/calculated exposure value of each source; Limiti is the applicable limit of each source. The device under evaluation is able to transmit simultaneously using SRD 5 MHz and Bluetooth LE / Proprietary 2.4 GHz, therefore the worst case multiple frequencies calculation will be as follow: 0.042 9.59 + = 0.026 + 0.114 = 0.152 < 1 Limit 1.6 83 Report No: (NIE) 57186RAN.002A1 Page 19 of 23 2019-08-29
