This document presents an RF exposure evaluation report for a portable device with FCC ID: 2BO2M-ZJ024. The evaluation was conducted by Shenzhen CTB Testing Co., Ltd. to ensure compliance with FCC regulations regarding radio frequency energy exposure. Specifically, the device was assessed according to §15.247(e)(i) and §1.1307(b)(1), which mandate that systems operate in a manner that does not expose the public to excessive radio frequency energy levels.
The report utilizes the guidelines outlined in KDB447498 D01 General RF Exposure Guidance V06 to determine SAR test exclusion thresholds for frequencies between 100 MHz and 6 GHz at test separation distances of ≤ 50 mm. The calculation considers the maximum power of the channel, including tune-up tolerance, and the minimum test separation distance. The formula used is [(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.
The results of the evaluation indicate that the device meets the SAR test exclusion criteria, with the maximum result being 0.78490, which is below the FCC limit of 3.0 for 1g SAR. Therefore, the device is deemed compliant with RF exposure regulations.
