FCC ID:2AOSJ-EKPL2 RF Exposure Evaluation According toKDB 447498 D01 General RF Exposure Guidance v06and part 2.1093， Unless specifically required by thepublished 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 correspondingSAR Test Exclusion Thresholdcondition(s), listed below, is (are) satisfied. For 100 MHz to 6 GHz and test separation distances≤5mm,the1-gand10-gSARtest exclusion thresholds aredetermined by the following: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)]ꞏ[√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 thenearest mW and mm before calculation The result is rounded to one decimal place for comparison Here, So a SAR test is not required Mode Frequen cy (MHz) Max Power (dBm) Target power W/ tolerance (dBm) Max tune up power tolerance (dBm) Max Power (mW) Min.
