FCC ID : 2AKLL-CREATORMAX RF EXPOSURE EVALUATION METHOD 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 3D Printer Frequency band WLAN: 2.412GHz ~ 2.462GHz (Operating) WLAN: 5.150GHz ~ 5.250GHz WLAN: 5.725GHz ~ 5.850GHz Others Device category Portable (<20cm separation) Mobile (>20cm separation) Others Exposure classification Occupational/Controlled exposure (S = 5mW/cm2) General Population/Uncontrolled exposure (S=1mW/cm2) Antenna diversity Single antenna Multiple antennas Tx diversity Rx diversity Tx/Rx diversity Max. output power 15.dBm (0.032W) Antenna gain (Max) 0 dBi Evaluation applied MPE Evaluation SAR Evaluation Limits for Maximum Permissible Exposure(MPE) Frequency Electric Field Magnetic Field Power Average Range(MHz) Strength(V/m) Strength(A/m) Density(mW/cm2) Time (A) Limits for Occupational/Control Exposures 300-1500 -- -- F/300 6 1500-100000 -- -- 5 6 (B) Limits for General Population/Uncontrol Exposures 300-1500 -- -- F/1500 6 1500-100000 -- -- 1 30 transmission formula: Pd=(Pout*G)\(4*pi*R2) Where Pd= Power density in mW/cm2 Pout=output power to antenna in mW G= gain of antenna in linear scale Pi=3.1415 R= distance between observation point and center of the radiator in cm Pd the limit of MPE, 1mW/cm2. If we know the maximum gain of the antenna and

FCC ID : 2AKLL—CREATORMAX totel power input to the antenna, through the caloulation, we will know the distance where the MPE limit is reached. SAR Test Exclusion Thresholds for 100 MHz — 6 GHz and S 50 mm Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table.

When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion.
