Chilingxiang, Qishantou, Santun, Houjie, Dongguan, Guangdong, China Tel: 86-769-83081888-808 Report Number: ESTE-R2408263 Date of Test: Aug. 16, 2024 ~Aug. 27, 2024 Date of Report: Aug. 30, 2024 Page 2 of 3 Report No. ESTE-R2408263 1. Applicable Standards FCC Part 2(Section 2.1093) FCC KDB 447498 D04 Interim General RF Exposure Guidance v01 2. Exposure Evaluation of Portable or Mobile Devices Human exposure to RF emissions from portable devices (47 CFR §2.1093), as defined by the FCC, must be evaluated with respect to the FCC-adopted limits for SAR. Evaluation of mobile devices, as defined by the FCC, may also be performed with respect to SAR limits, but in such cases it is usually simpler and more cost-effective to evaluate compliance with respect to field strength or power density limits. For certain devices that are designed to be used in both mobile and portable configurations similar to those described in 47 CFR §2.1091(d)(4), such as certain desktop phones and wireless modem modules, compliance for mobile configurations is also satisfied when the same device is evaluated for SAR compliance in portable configurations. The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 300 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. Page 3 of 3 Report No. ESTE-R2408263 3. Evaluation Results Mode Frequency (MHz) Peak output Power （dBm） Antenna Gain (dBi) effective radiated power （dBm） Target power (dBm) Max. Target power (mW) SAR Test Exemption Limit (mW) BLE 1M 2402 1.06 -1.78 -2.87 1±1 1.585 2.72 2440 1.08 -1.78 -2.85 1±1 1.585 2.72 2480 1.83 -1.78 -2.1 1±1 1.585 2.72 Note: 1. Limited=3060*(0.5/20)^x, x=-log(60/(3060*√f)). 2. We choose f=2.48GHz (Highest frequency operate at bluetooth) to calculate MPE limit as higher frequency will have lower MPE limits. 3. SAR Test Exclusion Thresholds is 2.72mW for separation distance 5mm. Therefore, SAR test is not required. End of Test Report
