Report No.: 2504A00276E-RF Rev:A/4.0(2024/11/01) Page 5 of 6 TR-4-E-R051 RF EXPOSURE Applicable Standard According to FCC §2.1093, systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. According to KDB 447498 D01 General RF Exposure Guidance v06 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(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, where 1. f(GHz) is the RF channel transmit frequency in GHz. 2. Power and distance are rounded to the nearest mW and mm before calculation. 3. The result is rounded to one decimal place for comparison. 4. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test Exclusion. Test result For worst case: Frequency (MHz) Tune-Up Conducted Output Power # (dBm) Tune-Up Conducted Output Power # (mW) Distance (mm) Calculated Value Threshold (1-g SAR) SAR Test Exclusion 2402-2480 5.00 3.16 5 1.0 3 Yes Note: The tune-up conducted power is declared by the applicant. Result: No SAR test is required. Shenzhen Accurate Technology Co., Ltd. Report No.: 2504A00276E-RF Rev:A/4.0(2024/11/01) Page 6 of 6 TR-4-E-R051 EXHIBIT A-EUT PH…
