FCC ID: 2AYJK-BLITZ2 RF EXPOSURE EVALUATION METHOD According to KDB 447498 D01 General RF Exposure Guidance v06, 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 According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) Radiation as specified in §1.1307(b) EUT Specification EUT Wireless Game Controller Frequency band (Operating) WLAN: 2.412GHz ~ 2.462GHz WLAN: 5.150GHz ~ 5.250GHz WLAN: 5.725GHz ~ 5.850GHz Others BT:2402-2480MHz SLE: 2402-2480MHz 2404-2478MHz 2405-2477MHz Device category Portable (<20cm separation) Mobile (>20cm separation) Others Exposure classification Occupational/Controlled exposure (S = 5mW/cm2) General Population/Uncontrolled exposure (S=1mW/cm 2 ) Antenna diversity Single antenna Multiple antennas Tx diversity Rx diversity Tx/Rx diversity Max. output power BT LE: -8.124 dBm SLE: -1.239dBm Antenna gain (Max) 1.8dBi Evaluation applied MPE Evaluation SAR Evaluation FCC ID: 2AYJK-BLITZ2 RF EXPOSURE EVALUATION METHOD SAR Test Exclusion Thresholds for 100 MHz – 6 GHz and ≤ 50 mm Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. 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 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 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.

Simultaneous Transmission SAR Evaluation The [Σ of (the highest estimated SAR BT LE + estimated SAR SLE ) /1.60] = (0.0474 + 0.237 ) = 0.18 < 1.0 Conclusion: No SAR is required.
