When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion Page 2 of 2 1.2 EUT RF EXPOSURE EVALUATION Operational Mode: EDR （8-DPSK worst case） Channel Maximum Peak Conducted Output Power (dBm) Tune up tolerance (dB) Maximum tune-up Power(dB m) Maximum tune-up Power(mW ) Calculated value Exclusion threshold 2402MHz 1.57 ±1 2.57 1.81 0.56 3 2441MHz 1.97 ±1 2.97 1.98 0.62 3 2480MHz 2.60 ±1 3.6 2.29 0.71 3 Conclusion: the calculated value ≤3.0, SAR is exempted.
