Shenzhen Huaxia Testing Technology Co., Ltd Report No.: CQASZ20180700073E-02 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 4.1.3 EUT RF Exposure Page:5 of 6

Shenzhen Huaxia Testing Technology Co., Ltd Report No.: CQASZ20180700073E-02 For BT: Measurement Data GFSK mode Test channel Peak Output Power (dBm) Lowest -0.210 Middle -0.560 Highest -1.060 π/4DQPSK mode Test channel Peak Output Power (dBm) Lowest -0.350 Middle -0.630 Highest -1.150 8DPSK mode Test channel Peak Output Power (dBm) Lowest -0.370 Middle -0.630 Highest -1.060 The Max Conducted Peak Output Power is -0.210dBm in lowest channel(2.402GHz); The best case gain of the antenna is 0dBi. EIRP= -0.210dBm + 0dBi = -0.210dBm -0.210dBm logarithmic terms convert to numeric result is nearly 0.953mW According to the formula. calculate the EIRP test result: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] General RF Exposure = (0.953mW / 5 mm ) x √2.402GHz = 0.295 ① SAR requirement: S= 3.0 ②; ① < ②. So the SAR report is not required. Remark: The Max Conducted Peak Output Power data refer to report Report No.: CQASZ20180700073E-01 Page:6 of 6
