Power and distance are rounded to the nearest mW and mm before calculation. 3. The result is rounded to one decimal place for comparison. 4. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test Exclusion. Measurement Result For worst case: Frequency (MHz) Maximum Tune-up power Calculated Distance (mm) Calculated Value Threshold (1-g SAR) SAR Test Exclusion (dBm) (mW) 2402-2480 5.0 3.16 5 1.0 3.0 Yes Result: No Standalone SAR test is required
