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 -6.92 ±1 -5.92 0.26 0.08 3 2441MHz -6.43 ±1 -5.43 0.29 0.09 3 2480MHz -5.85 ±1 -4.85 0.33 0.10 3 Conclusion: the calculated value ≤3.0, SAR is exempted.
