4    SAR Evaluation
4.1 RF Exposure Compliance Requirement
4.1.1 Standard Requirement
     According to KDB447498D01 General RF Exposure Guidance v06
     4.3.1. Standalone SAR test exclusion considerations
            Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head
     or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement
     or numerical simulation, is not required when the corresponding SAR Exclusion Threshold condition,
     listed below, is satisfied.
4.1.2 Limits
     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(G Hz) is the RF cha nne l tra ns m it fre que ncy in G Hz
                                                                                                   17
      P owe r a nd dis ta nce a re rounde d to the ne a re s t m W a nd m m be fore ca lcula tion
      The re s ult is rounde d to one de cim a l pla ce for com pa ris on
     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 is applied to determine SAR test exclusion
