       Description of the EUT:                   50126-R is a Outlet Wireless Remote operation on 433.92MHz.


2.     Limit and Guidelines on Exposure to Electromagnetic Fields
       According to§15.231(c)(e) 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


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


       According to ANSI C63.10-2013 (9.5 Equations to calculate EIRP),




       Field strength (EMeas)                                                 87.43 (dBuV/m) f=433.92MHz
       Measurement Distance (dMeas)                                           3m
       Equivalent Isotropically Radiated                                      -7.73dBm=0.17mW
       Power(EIRP):


       Conducted Power + tune up tolerance 0.17mW
       Distance = 5 mm
       f = 433.92 GHz
       [0.17/5] * SQRT(0.43392) =
       0.022 ≤ 3.0
       Therefore, excluded from SAR testing.
