FCC ID:2BD5T-T10 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 numericalsimulation, 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≤5 mm, the 1-g and 10-g SAR test exclusion thresholds are determined 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 the nearest mW andmm before calculation The result is rounded to one decimal place for comparison Here, BT Mode Freque ncy (MHz) Max Power (dBm) Target power W/ tolerance (dBm) Max tune up power tolerance (dBm) Max Power (mW) Min.
