This document presents the RF exposure compliance assessment for a portable device, adhering to FCC regulations outlined in §15.247(e)(i) and §1.1307(b)(1). The evaluation ensures that the device operates within safe radio frequency energy exposure limits, as per the Commission's guidelines. The assessment follows the procedures detailed in KDB447498 D01 General RF Exposure Guidance V06.
The report focuses on 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 method involves the formula: [(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. Power and distance values are rounded for calculation, and the final result is rounded to one decimal place.
The device's BLE (Bluetooth Low Energy) functionality was tested, and the results indicate compliance with SAR test exclusion thresholds. The maximum calculated result is 0.49918, which is below the FCC limit of 3.0 for 1g SAR, confirming that the device meets the required safety standards.
