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 nd distance are rounded to the nearest mW and mm before calculation 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 Shenzhen Huaxia Testing Technology Co., Ltd Report No.: CQASZ20191201321E-02 Page:6 of 6 4.1.3 EUT RF Exposure Measurement Data GFSK mode Test channel Peak Output Power (dBm) Tune up tolerance (dBm) Maximum tune-up Power (dBm) (mW) Lowest(2402MHz) -6.160 -6.5±1 -5.5 0.282 Middle(2441MHz) -6.790 -6.5±1 -5.5 0.282 Highest(2480MHz) -6.380 -6.5±1 -5.5 0.282 π/4DQPSK mode Test channel Peak Output Power (dBm) Tune up tolerance (dBm) Maximum tune-up Power (dBm) (mW) Lowest(2402MHz) -6.230 -6.5±1 -5.5 0.282 Middle(2441MHz) -6.850 -6.5±1 -5.5 0.282 Highest(2480MHz) -6.420 -6.5±1 -5.5 0.282 8DPS…
