This document details the RF exposure evaluation for a portable device manufactured by Shenzhen CTB Testing Co., Ltd., identified by FCC ID: 2BLRA-NA01. The evaluation ensures compliance with FCC regulations, specifically §15.247(e)(i) and §1.1307(b)(1), which mandate that devices operate in a manner that does not expose the public to excessive radio frequency energy.
The assessment adheres to KDB447498 D01 General RF Exposure Guidance V06, utilizing 1-g and 10-g SAR test exclusion thresholds for frequencies between 100 MHz and 6 GHz at test separation distances of ≤ 50 mm. The calculations consider the maximum power of each channel, including tune-up tolerance, and the minimum test separation distance. The results are compared against established SAR limits to determine if further SAR testing is required.
The evaluation covers various wireless modes, including EDR, BLE (1M and 2M), and 2.4GHz WiFi (ANT1, ANT2, and ANT1+ANT2 configurations). The document provides detailed tables showing conducted power, tune-up power, distance, calculated SAR values, and SAR exclusion thresholds for each mode and channel. The conclusion confirms that the device meets the FCC's SAR limits, ensuring safe operation for the public.
