Document DEVICE REPORTGetApplicationAttachment.html?id=8200916Shenzhen CTB Testing Co., Ltd. FCC ID:2AML6KR810 Portable device According to §15.247(e)(i) and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission's guidelines. According to KDB447498 D01 General RF Exposure Guidance V06 The 1-g SAR 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 When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion.
