This document presents an RF exposure evaluation for the MD-TWS-039 device, conducted to ensure compliance with FCC regulations. The evaluation adheres to §1.1307(b)(1), §1.1310, and §2.1093 of the FCC guidelines, as well as KDB447498 v06, which outlines procedures for mobile and portable devices. The primary objective is to determine whether the device meets the SAR test exclusion thresholds, thereby ensuring public safety regarding radio frequency energy exposure.
The evaluation considers the maximum conducted output power, tune-up tolerance, and minimum test separation distance. The results indicate that the device satisfies the SAR test exclusion conditions, as the calculated values are below the specified thresholds for both 1-g and 10-g SAR limits. Specifically, the evaluation covers GFSK, π/4DQPSK, and 8-DPSK modulation schemes, with detailed manufacturing tolerances provided for each channel. The antenna distance is considered in the evaluation, and the final results confirm compliance with the FCC's RF exposure limits.
