This document details the Radio Frequency (RF) exposure evaluation for a portable device with FCC ID 2ASAU-GTS8. The evaluation ensures compliance with §15.247(e)(i) and §1.1307(b)(1) of FCC regulations, which mandate that devices operate in a manner that does not expose the public to excessive RF energy levels. The assessment follows the guidelines outlined in KDB447498 D01 General RF Exposure Guidance V06.
The report focuses on determining whether Specific Absorption Rate (SAR) testing is required based on established thresholds for 1-g and 10-g SAR at test separation distances of ≤ 50 mm. These thresholds are calculated using a formula that considers the maximum power of the channel, including tune-up tolerance, the minimum test separation distance, and the RF channel transmit frequency. The document includes tables showing the conducted power, tune-up power, and calculated SAR values for BLE:1M and BLE:2M modes. The conclusion states that the maximum calculated result is below the FCC limit for 1g SAR, indicating compliance.
