Federal Communications Commission (FCC) Statement 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. 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: ƽReorient or relocate the receiving antenna. ƽIncrease the separation between the equipment and receiver. ƽConnect the equipment into an outlet on a circuit different from that to which the receiver is connected. ƽConsult the dealer or an experienced radio/TV technician for help. Warning: Changes or modifications made to this device not expressly approved by SHENZHEN MIFANG NETWORK TECHNOLOGY CO., LTD. may void the FCC authorization to operate this device. Note: The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications to this equipment. Such modifications could void the user’s authority to operate the equipment. RFexposurestatement: The transmitter must not be colocated or operated in conjunction with any other antenna or transmitter. This equipment complies with the FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 5mm between the radiator and any part of your body.

RF Exposure evaluation According to 447498 D01 General RF Exposure Guidance v05 The 1‐gand10‐gSARtest 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‐gSARand≤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 For Bluetooth BR/EDR pt=0.64dBm=1.159mW at 2480MHz So (1.159mW/5mm)x√2.480GHz = 0.37<3 Then SAR evaluation is not required
