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. Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 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. To maintain compliance with FCC’s RF Exposure guidelines, This equipment should be installed and operated with minimum distance between 20cm the radiator your body: Use only the supplied antenna.

FCC ID: 2AWW4-DOT-V14 Maximum Permissible Exposure (MPE) 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) MPE Calculation Method E (V/m) ＝ d GP**30 Power Density: Pd (W/m²) ＝ 377 2 E E ＝ Electric field (V/m) P ＝ Average RF output power (W) G ＝ EUT Antenna numeric gain (numeric) d ＝ Separation distance between radiator and human body (m) The formula can be changed to Pd ＝ 2 *377 **30 D GP From the EUT RF output power, the minimum mobile separation distance, d=0.2m, as well as the gain of the used antenna, the RF power density can be obtained. Measurement Result Operation Frequency: BT: 2402-2480MHz Power density limited: 1mW/ cm 2 Antenna Type: PCB antenna WIFI antenna gain: -0.3dBi; R=20cm mW=10^(dBm/10) antenna gain Numeric=10^(dBi/10)= 10^(-0.3/10)=0.93 Channel Freq.
