This document presents the RF exposure evaluation for a wireless headphones product. The evaluation is conducted in accordance with KDB447498D04 General RF Exposure Guidance v01. The document outlines the product name, FCC ID (2AFTU-DD037), and the test standard used for the evaluation.
The evaluation includes formulas for calculating the power threshold (Pth) based on the equivalent isotropically radiated power (ERP) at 20 cm distance. These formulas are provided for different frequency ranges. The document also includes a table of example power thresholds for various frequencies and distances, serving as an illustration.
The document concludes with the RF exposure evaluation results, stating that the maximum output power is 0.253dBm@2480MHz, and the ERP is 0.833dBm. The calculated power is less than the required threshold, therefore SAR evaluation is not required.
