Bay Area Compliance Laboratories Corp. (Kunshan) Report No.: RKSA260611001-00A Page 13 of 47 FCC §1.1307(b) & §2.1093 - RF EXPOSURE Applicable Standard According to§2.1093and §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. Calculated Data: Mode Frequency Range (MHz) Max Tune-up Conducted Power Calculated Distance (mm) Calculated Value Threshold (1-g SAR) SAR Test Exclusion (dBm) (mW) BLE 2402-2480 -0.1 0.98 5 0.3 3.0 Yes Note: 1. The above tune up power were declared by the manufacturer. Result: The device meets the exemption requirement.
