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 calculation17 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 7 Shenzhen Huaxia Testing Technology Co., Ltd Report No.: CQASZ20191101112E-02 4.1.3 EUT RF Exposure Measurement Data Test channel Lowest(2402MHz) Middle(2441MHz) Highest(2480MHz) Test channel Lowest(2402MHz) Middle(2441MHz) Highest(2480MHz) Test channel Lowest(2402MHz) Middle(2441MHz) Highest(2480MHz) GFSK mode Peak Output Power Tune up tolerance (dBm) (dBm) -2.690 -2.5±1 -1.920 -2.0±1 -1.100 -1.5±1 /4DQPSK mode Peak Output Power Tune up tolerance (dBm) (dBm) -0.070 0±1 0.840 1.0±1 1.600 1.5±1 8DPSK mode Peak Output Power Tune up tolerance (dBm) (dBm) 0.390 1.280 2.200 0±1 1.0±1 2.0±1 Maximum tune-up Power (dBm) (mW) -1.5 0.708 -1 0.794 -0.5 0.891 Maximum tune-up Power (dBm) (mW) 1 1.259 2 1.585 2.5 1.778 Maximum tune-up Power (dBm) (mW) 1 1.259 2 1.585 3 1.995 Worst case: 8DPSK Channel Maximum Peak Conducted Output Power (dBm) Tune up tolerance (dBm) Maximum tuneup Power (dBm) (mW) Lowest (2402MHz) 0.390 0±1 1 1.259 Middle (2441MHz) 1.280 1.0±1 2 1.585 Highest (2480MHz) 2.200 2.0±1 3 1.995 Conclusion: the calculated value 3.0, SAR is exempted.
