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(GHz) is the RF channel transmit frequency in GHz
        Power and distance are rounded to the nearest mW and mm before calculation17
        The result is rounded to one decimal place for comparison
     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
