        Standards   _: FCC Title 47 Part 2.1091, OET Bulletin 65 Supplement C


    The above equipment has been tested and found compliance with the requirement of the relative
    standards by BTL Inc.
    The test data, data evaluation, and equipment configuration contained in our test report (Ref No.
    BTL—FCCP—2—1906C154) were obtained utilizing the test procedures, test instruments, test sites

   2. MPE CALCULATION METHOD

               Calculation Method of RF Safety Distance:

               $   . 16_HBP
                    in 4n‘

             where:
             S = power density
             P = power input to the antenna
             G = power gain of the antenna in the direction of interest relative to an isotropic radiator
             R = distance to the center of radiation of the antenna
