FCC ID: 2ATU8-T2 RF Exposure Evaluation According to KDB 447498 and part 2.1093，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 Test Exclusion Threshold condition(s), listed below, is (are) satisfied. For 100 MHz to 6 GHz and test separation distances ≤ 50 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)] · [√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 and mm before calculation The result is rounded to one decimal place for comparison Here, EDR-worst mode and channel Mode Channel Max Power (dBm) Tune up tolerance (dBm) Maximum tune-up (dBm) (mW) π/4-DQPSK Highest -0.17 0±1 1 1.259 BLE-worst mode and channel Mode Channel Max Power (dBm) Tune up tolerance (dBm) Maximum tune-up (dBm) (mW) BLE Highest -2.36 -2±1 -1 0.794 Mode Maxtune-up Power (dBm) Max tune-up Power (mW) Frequency (MHz) Min. distance (mm) Calc. thresholds limit π/4-DQPSK 1 1.259 2480 < 5mm 0.3965 3.0 BLE -1 0.794 2440 < 5mm 0.248 3.0 So a SAR test is not required
