This document presents the Radio Frequency (RF) exposure evaluation for a device with FCC ID: 055T312324, conducted by Shenzhen Tongzhou Testing Co., Ltd. The evaluation adheres to section B.4 of the 447498 D04 Interim General RF Exposure Guidance v01, which outlines SAR-based thresholds derived from frequency, power, and separation distance of the RF source. The report details the formulas used to determine these thresholds, considering factors such as maximum time-averaged power or ERP.
The evaluation includes conducted power results for various test modes (DH5, 2DH5, 3DH5) across different frequencies (2402 MHz, 2441 MHz, 2480 MHz) using Antenna 1. Manufacturing tolerances for GFSK, π/4-DQPSK, and 8-DPSK are also specified. The maximum ERP and conducted power, including tune-up, are calculated, and the exemption limit is determined. The report concludes that the SAR evaluation is not required, as the device complies with the routine evaluation exemption criteria outlined in the guidance.
