No non-compliance noted.

Calculation
              30 × P × G        E2
Given    E=              & S=
                  d             377
         Where E = Field strength in Volts / meter
                P = Power in Watts
                G = Numeric antenna gain
                d = Distance in meters
                S = Power density in milliwatts / square centimeter
Combining equations and re-arranging the terms to express the distance as a function of
the remaining variables yields:
              30 × P × G
         S=
               377 d 2

Changing to units of mW and cm, using:
         P (mW) = P (W) / 1000 and
         d (cm) = d(m) / 100

Yields
              30 × (P / 1000) × G            P×G
         S=                       = 0.0796 ×       Equation 1
               377 × (d / 100)

                                              d2
         Where d = Distance in cm
               P = Power in mW
               G = Numeric antenna gain
               S = Power density in mW / cm2


                                                                                            Page:     7/7

5. MAXIMUM PERMISSIBLE EXPOSURE

Substituting the MPE safe distance using d = 20 cm into Equation 1:
  S = 0.000199 × P × G
Where P = Power in mW
      G = Numeric antenna gain
      S = Power density in mW / cm2
