Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: 2501X32127E-RF-00A TR-EM-RF003 Page 54 of 56 Version 4.1 RF EXPOSURE EVALUATION RF Exposure Evaluation Applicable Standard According to FCC §2.1093 and §1.1307(b) (1), 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. Measurement Result For worst case: Frequency (MHz) Tune-up power # (dBm) Tune-up power # (mW) Distance (mm) Calculated value Threshold (1-g SAR) SAR Test Exclusion 248086.315.01.993.0Yes Note: Max tune-up conducted power # and antenna gain # was declared and provided by the applicant Result: Compliant
