This document presents the RF exposure evaluation for a portable device, conducted in accordance with FCC regulations §15.247(e)(i) and §1.1307(b)(1). The evaluation ensures that the device operates within the Commission's guidelines for radio frequency energy exposure. The assessment follows the procedures outlined in KDB447498 D01 General RF Exposure Guidance V06.
The 1-g SAR and 10-g SAR test exclusion thresholds are determined for test separation distances ≤ 50 mm, based on the formula provided. The formula considers the maximum power of the channel, including tune-up tolerance, and the RF channel transmit frequency in GHz. Power and distance values are rounded to the nearest mW and mm before calculation, and the result is rounded to one decimal place for comparison.
The evaluation includes a table summarizing the channel frequency, conducted power, tune-up power, and calculated SAR exclusion threshold. The results indicate whether SAR testing is required based on the calculated values. The conclusion states that the maximum result is below the FCC limit for 1g SAR, indicating compliance with RF exposure regulations.
