Shenzhen Huaxia Testing Technology Co., Ltd Report No.: CQASZ20180500101E-03 5 SAR Evaluation 5.1 RF Exposure Compliance Requirement 5.1.1 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. 5.1.2 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 17 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 5.1.3 EUT RF Exposure For BT: Measurement Data GFSK mode Test channel Peak Output Power (dBm) Lowest 2.420 Middle 2.180 Highest 0.460 π/4DQPSK mode Test channel Peak Output Power (dBm) Lowest 2.290 Middle 2.080 Highest 0.410 8DPSK mode Test channel Peak Output Power (dBm) Lowest 2.320 Middle 2.140 Highest 0.490 Remark: The Conducted Peak Output Power data refer to report Report No.: CQASZ20180500101E-01 Page:5 of 6

CQ‘A Shenzhen Huaxia Testing Technology Co., Ltd LE E ;E ;“ Report No.: CQASZ20180500101E—03 For BLE: Measurement Data GFSK mode Test channel Peak Output Power (dBm) Lowest —5.6 Middle —5.81 Highest —5.41 Remark: The Conducted Peak Output Power data refer to report Report No.: CQASZ20180500101E—02 BDR, EDR and BLE can not simultaneous transmitting at same time. The worst case data: GFSK_lowest channel The Max Conducted Peak Output Power is 2.42dBm in lowest channel(2.402GHz); The best case gain of the antenna is —0.73dBi. EIRP= 2.42dBm — 0.73dBm= 1.69dBm 1.69Bm logarithmic terms convert to numeric result is nearly 1.48mW According to the formula. calculate the EIRP test result: [{max. power of channel, including tune—up tolerance, mW)/{min. test separation distance, mm)] — [Nf(GHz)] General RF Exposure = (1.48mW /5 mm ) x v2.402GHz =0.46 ® SAR requirement: S= 3.0 @; 0 <@. So the SAR report is not required. Page:6 of 6
