BOMGE 1 2 power 2 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: -- 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. Warning: changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment

FCC RF Exposure EUT Description: UHF wireless microphone system Model No.: BG-250U,BG-260U,BG-280U,BG-228U,BG-210U,U-260,U-250,U-280,U-210,U-220 FCC ID: 2AZWQ-BG250U Equipment type: Portable Device 1. Test Procedure According to KDB 447498 D01 General RF Exposure Guidance v06 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 The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is≤50 mm and for transmission frequencies between 100 MHz and 6GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. 2. Test Result of RF Exposure Evaluation Wireless Microphone CH/Frequency Conducted Peak Output power（dBm/ mW） 470MHz- 608MHz 8.935/7.825 Turn-up power Mode Conducted Peak power range(dBm) wireless microphone 6.00-9.00 FCC exclusion condition as below: [608MHz, 9dBm/7.943mW) output power] (7.943mW /5mm) *[√0.608(GHz)] =1.239<3.0 for 1-g SAR Conclusion: No SAR is required
