RADIO FREQUENCY EXPOSURE
  Limit
    According to section 4.3.1 of KDB 447498 D01 General RF Exposure Guidance v06, SAR evaluation is
    required if the separation distance between the user and/or bystander and the antenna and/or radiating
    element of the device is less than or equal to 20 cm, except when the device operates at or below the
    applicable output power level (adjusted for tune-up tolerance) for the specified separation distance
    defined in Appendix A.

    The antenna gain of the EUT for BT is 0.0dBi (Max). the Maximum Eirp is used for Routine Evaluation
    Exemption according to section 4.3.1 of KDB 447498 D01.
    So, the SAR evaluation is not required.
