Report Number: 68.930.18.0015.01A RF exposure Estimation Introduction Product Type: Ultrasonic Pocket Doppler Model: SD1 (FCC ID: SMQSD1MEDAN) is a Ultrasonic Pocket Doppler, which contain 2.4GHz Transmitter Module. 1. Limit and Guidelines on Exposure to Electromagnetic Fields According to§15.247(e)(i) 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 Mobile Portable RF Exposure, no SAR required if power is lower than the flowing threshold: 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 calculation25 • 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. 2. Calculation method [(max. power of` channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 EIRP + tune up tolerance = -1.34dBm= 0.7mW Distance = 5 mm f = 2.402 GHz [0.7/5] * SQRT(2.402) =0.22 0.22 ≤ 3.0 Therefore, excluded from SAR testing.
