Bay Area Compliance Laboratories Corp. (Kunshan) Report No.: RKSB260624001-00A Page 13 of 43 FCC§15.247 (i), §1.1310 &§2.1093 – RF EXPOSURE Applicable Standard According to§15.247(i) and §1.1310, 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 KDB447498 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 • f(GHz) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation • The result is rounded to one decimal place for comparison • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm according to 5) in section 4.1 is applied to determine SAR test exclusion. Measurement Result 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 1.55 1.43 5.0 0.4 3.0 Yes Note: 1. For the above tune up power were declared by the manufacturer. 2. The tune-up output power was declared by the manufacturer, which is Maximum Test Output Conducted Power+1dB.
