1.2 Standard Applicable According to §1.1307(b)(1) and KDB 447498 D01 General RF Exposure Guidance v06, system operating under the provisions of this section shall be operating in a manner that the public is not exposed to radio frequency energy level in excess limit for maximum permissible exposure. (a) Limits for Occupational / Controlled Exposure Electric Field Magnetic Field Averaging Times Frequency range Power Density Strength (E) Strength (H) | E |2, | H |2 or (MHz) (S) (mW/cm2) (V/m) (A/m) S (minutes) 0.3-3.0 614 1.63 (100)* 6 3.0-30 1842/f 4.89/f (900/f)* 6 30-300 61.4 0.163 1.0 6 300-1500 / / F/300 6 1500-100000 / / 5 6 (b) Limits for General Population / Uncontrolled Exposure Electric Field Magnetic Field Averaging Times Frequency range Power Density Strength (E) Strength (H) | E |2, | H |2 or (MHz) (S) (mW/cm2) (V/m) (A/m) S (minutes) 0.3-1.34 614 1.63 (100)* 30 1.34-30 824/f 2.19/f (180/f)* 30 30-300 27.5 0.073 0.2 30 300-1500 / / F/1500 30 1500-100000 / / 1 30 Note: f = frequency in MHz: * = Plane-wave equivalents power density 1.3 MPE Calculation Method S = (30*P*G) / (377*R2) S = power density (in appropriate units, e.g., mw/cm2) P = power input to the antenna (in appropriate units, e.g., mw) G = power gain of the antenna in the direction of interest relative to an isotropic radiator, the power gain factor is normally numeric gain. R = distance to the center of radiation of the antenna (in appropriate units, e.g., cm)

1.4 MPE Calculation Result Maximum Tune-Up output power: 18 (dBm) Maximum peak output power at antenna input terminal: 63.1 (mW) Prediction distance: >20(cm) Prediction frequency: 2437 (MHz) Antenna gain: 0(dBi) Directional gain (numeric gain): 1 The worst case is power density at prediction frequency at 20cm: 0.013(mw/cm2) MPE limit for general population exposure at prediction frequency: 1 (mw/cm2) Result: Pass
