FCC Statement: 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 to an outlet on a circuit different from that to which the receiver is connected. 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: Modifications to this product will void the user’s authority to operate this equipment.

RF Exposure evaluation Product Description: Bluetooth Adapter Model Number: BT-BOX-01 FCC ID: 2AEJ7001 According to 447498 D01 General RF Exposure Guidance v05 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 According to the follow transmitter output power（P t ）formula： P t =（E x d） 2 /（30 x g t ） P t =transmitter output power in watts g t =numeric gain of the transmitting antenna (unitess) E=electric field strength in V/m d=measurement distance in meters (m) According to the above test data,Emax=98.80dBuv/m=0.087V/m,d=3m,g t =1 P t =（E x d） 2 /（30 x g t ）=(0.087x3) 2 /(30x1)=0.0023W=2.3mW The result is rounded to one decimal place for comparison Worse case is as below: [2480MHz -2.3mW output power] (2.3mW /50mm) .[√2.480(GHz)]= 0.07<3.0 for 1-g SAR Then SAR evaluation is not required NOTE: The transmitter output power formula you can refer to Part15F (K). For the maximum power, you can refer FCC test report.
