Shenzhen Huaxia Testing Technology Co., Ltd Report No.: CQASZ20191001055E-03 4 SAR Evaluation 4.1 RF Exposure Compliance Requirement 4.1.1 Standard Requirement According to KDB447498D01 General RF Exposure Guidance v06 4.3.1. Standalone SAR test exclusion considerations 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 Exclusion Threshold condition, listed below, is satisfied. 4.1.2 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, 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 calculation17 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 Page:6 of 8

Shenzhen Huaxia Testing Technology Co., Ltd Report No.: CQASZ20191001055E-03 4.1.3 EUT RF Exposure 1) For BLE Measurement Data GFSK mode Tune up tolerance Maximum tune-up Power Test channel Peak Output Power (dBm) (dBm) (dBm) (mW) Lowest(2402MHz) 1.58 1.0±1 2.0 1.585 Middle(2440MHz) 0.91 0±1 1.0 1.259 Highest(2480MHz) 1.31 0.5±1 1.5 1.413 Worst case: GFSK Maximum Peak Maximum tune- Tune up Conducted up Power Calculated Exclusion Channel tolerance Output Power value threshold (dBm) (dBm) (mW) (dBm) Lowest 1.58 1.0±1 2.0 1.585 0.491 (2402MHz) Middle 3.0 (2440MHz) 0.91 0±1 1.0 1.259 0.393 Highest (2480MHz) 1.31 0.5±1 1.5 1.413 0.445 Conclusion: the calculated value ≤3.0, SAR is exempted. Remark: The Max Conducted Peak Output Power data refer to report Report No.: CQASZ20191001055E-01 Page:7 of 8

Shenzhen Huaxia Testing Technology Co., Ltd Report No.: CQASZ20191001055E-03 2) For 2.4G eirp = pt x gt = (E x d)2/30 where: pt = transmitter output power in watts, gt = numeric gain of the transmitting antenna (unitless), E = electric field strength in V/m, ---10((dBμV/m)/20)/106 , d = measurement distance in meters (m)---3m, So pt = (E x d)2/30 / gt The worst case (refer to report CQASZ20191001055E-02) is below: Antenna polarization: Horizontal Frequency (MHz) Level (dBuV/m) Polarization 2467 100.21 Peak 2467 96.92 Average Antenna polarization: Vertical Frequency (MHz) Level (dBuV/m) Polarization 2467 99.65 Peak 2467 95.97 Average For 2467MHz wireless: Field strength = 100.21dBμV/m @3m Ant. gain 0dBi; so Ant numeric gain=1.0 So pt={[10(100.21/20)/106x3]2/30 /1.0}x1000mW =3.149mW So (3.149mW/5mm)x √2.467GHz = 0.989, 0.989<3.0 for 1-g SAR So the SAR report is not required.
