Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: 2401V84724E-RF-00 TR-EM-RF041 Page 11 of 40 Version 3.0 FCC§1.1307 (b) (1) & §2.1093- RF EXPOSURE 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 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. Result Mode Frequency (MHz) Maximum E- Field (dBuV/m@3 m) Maximum EIRP(dBm) Maximum EIRP (mW) Distance (mm) Calculated value Threshold (1-g SAR) SAR Test Exclusion GFSK 2402-2480 99.65 4.45 2.79 5 0.9 3 Yes Note: EIRP = E-Field – 95.2 @3m Result: Compliant.
