                            RF exposure Estimation for SD6 (Probe)


1.   Introduction
     EUT is an Ultrasonic TableTop Doppler, which contain Bluetooth function inside.


2.   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 D01 Mobile Portable RF Exposure v05r02, 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.


3.   Calculation method


     FCC ID: SMQSD6PEDAN
     [(max. power of` channel, including tune-up tolerance, mW)/(min. test separation distance,
     mm)] ·[√f(GHz)] ≤ 3.0


     Conducted Power + tune up tolerance = 0.96mW (-0.18dBm)
     Distance = 5 mm
     f = 2.441 GHz

       [0.96/5] * SQRT(2.441) =0.30
       0.30 ≤ 3.0
       Therefore, excluded from SAR testing.
