This document presents an RF exposure evaluation report conducted by Shenzhen CTB Testing Co., Ltd. The evaluation adheres to §15.247(e)(i) and §1.1307(b)(1) of FCC regulations, ensuring that the device operates in a manner that does not expose the public to excessive radio frequency energy levels. The assessment also follows the guidelines outlined in KDB447498 D01 General RF Exposure Guidance V06.
The report focuses on determining the 1-g SAR and 10-g SAR test exclusion thresholds for frequencies between 100 MHz and 6 GHz, with test separation distances of ≤ 50 mm. The calculation involves the maximum power of the channel, including tune-up tolerance, and the minimum test separation distance, considering the RF channel transmit frequency in GHz. Power and distance values are rounded to the nearest mW and mm before calculation, and the final result is rounded to one decimal place for comparison.
The evaluation includes specific data for BLE:1M and BLE:2M modes, detailing channel frequencies, conducted power, tune-up power, distance, and calculated SAR values. The results are compared against the SAR exclusion threshold to determine if further SAR testing is required. The conclusion states that the maximum result is below the FCC Limit for 1g SAR.
