3.   SAR Test Exclusion
     As RF exposure evaluation of portable device, SAR test is not required when the evaluation results. According to

     KDB 447498 4.3.1, unless excluded by specific FCC test procedures, portable devices shall include SAR data for

     equipment approval. SAR test necessity will be based on the exclusion result.


     The test exclusion refers KDB 447498 as below:

     ≤50 mm:
     [(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



     >50 mm and <200 mm:
     a) [Power allowed at numeric threshold for 50 mm in step 1) + (test separation distance - 50 mm)·( f(MHz)/150)]

         mW, at 100 MHz to 1500 MHz

     b) [Power allowed at numeric threshold for 50 mm in step 1) + (test separation distance - 50 mm)·10] mW at > 1500

         MHz and ≤ 6 GHz

3.3 Evaluation Results

    The evaluation of SAR test reduction according to KDB447498

    SAR test is not required when the results showed “EXEMPT”.


                                                    SAR test reduction

    Exclusion Considerations: SAR is not required


    Note: 1. Calculated Value include string "mW",that is meam through compare output power with threshold, if the
              output power more than threshold value the SAR test should be perform. Otherwise,the SAR test could be
              exempt. (> 50 mm)
          2. Calculated Value only inculde number format, that is mean through compare output power with threshold,
             if the Calculated value more than 3, the SAR test should be perform. Otherwise, the SAR test could be
             exempt. (<50 mm)
          3. When an antenna qualifies for the standalone SAR test exclusion of KDB 447498 section 4.3.1 and also
             transmits simultaneously with other antennas, the standalone SAR value must be estimated according to
             KDB 447498 section "4.3.2. Simultaneous transmission SAR test exclusion considerations b) ".
          4. We used highest frequency and power, that result should be evaluated the worst case.
          5. Power and distance are rounded to the nearest mW and mm before calculation.
          6. The result is rounded to one decimal place for comparison.
          7. We use a minimum distance of 5 mm for bluetooth function.
