Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -Reorient or relocate the receiving antenna. -Increase the separation between the equipment and receiver. -Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -Consult the dealer or an experienced radio/TV technician for help. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

FCC ID : 2ADACJ51-C8 RF EXPOSURE EVALUATION 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) Limits for Maximum Permissible Exposure (MPE) Frequency Range(MHz) Electric Field Strength(V/m) Magnetic Field Strength(A/m) Power Density(mW/cm 2 ) Average 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 11.1 Friis transmission formula: Pd= (Pout*G)\ (4*pi*R 2 ) Where Pd= Power density in mW/cm 2 Pout=output power to antenna in mW G= Numeric gain of the antenna relative to isotropic antenna Pi=3.1416 R= distance between observation point and center of the radiator in cm Pd the limit of MPE, 1mW/cm 2 ,If we know the maximum gain of the nd total power input to the antenna, through the calculation, we will know the distance where the MPE limit is reached. RF Exposure Information: The radiated output power of this device meets the limits of FCC radio frequency exposure limits.This device should be operated with a minimum separation distance of 20cm (8 inches) between the equipment and a person's body. 11.2 Measurement Result BLE Antenna gain: 0 dBi Measured power (dBm) Tune-up power (dBm) Max tune-up power (dBm) Antenna Gain Numeric Evaluation result (mW/cm2 ) Power density Limits (mW/cm2 ) 4.43 3 to 5 5 1 0.0006 1 BT Antenna gain: 0 dBi Measured power (dBm) Tune-up power (dBm) Max tune-up power (dBm) Antenna Gain Numeric Evaluation result (mW/cm2 ) Power density Limits (mW/cm2 ) 8.5 7 to 9 9 1 0.0016 1 Wifi 2.4G Antenna gain: 0 dBi Directional gain: 3 dBi Measured power (dBm) Tune-up power (dBm) Max tune-up power (dBm) Antenna Gain Numeric Evaluation result (mW/cm2 ) Power density Limits (mW/cm2 ) 13.68 12 to 14 14 2.0 0.0100 1 CONCLUSION of simultaneous transmitter Both of the WIFI and BT can transmit simultaneously, the formula of calculated the MPE is: CPD1/LPD1+CPD2/LPD2+......etc. < 1 CPD = Calculation power density LPD = Limit of power density Therefore the worst-case situation is 0.0016 /1.00+0.0100 /1.00 = 0.0116, which is less than “1”, This confirmed that the device comply with FCC 1.1310 MPE limit.
