Shenzhen CTB Testing Technology Co., Ltd. FCC ID: 2BV5M-GTH5 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.

This is because factors such as motherboard consistency, assembly consistency, and variations in antenna assembly can all lead to deviations in antenna parameters.  Shenzhen Tuopin IoTIf  you have any questions, please contact us promptly.!  Phone:0755 ‐ 21073904 Postal  code:516300  R&DLonghua District, ShenzhenHua Yun Road1NumberJin Bolong IndustrygardenDistrict ABuilding410 ‐ 411 THANK YOU May you have a peace ful heart in this bustling and noisy wo rld. —Tuo Pin IoT
