FCC ID: 2A5I9-C400PRO RF Exposure Evaluation According to KDB 447498 D01 General RF Exposure Guidance v06 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 ≤ 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)] · [√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, Remark：1. BT Antenna gain is 1.5dBi, WIFI Antenna gain is 4.8 dBi (WIFI 5.1G); 5.42dBi (WIFI 5.8G) 2. WiFi2.4g, WiFi5g donot transmit at the same time BT and wifi can transmit at the same time 3. In the case of simultaneous launches for wifi and BT: The Max Calc. Thresholds : BT:0.2959, WiFi: 0.6707 BT and Wifi : 0.2959+0.6707 =0.9666≤ 1 So a SAR test is not required Operating Mode Frequency Measured Power Tune up tolerance Max.
