                                                Maximum Permissible Exposure

Test Specific Details
                            The objective of this test session is to perform final qualification testing of the EUT with respect to the
               Objective:
                            specification listed above.
         Test Engineer: David Bare

General Test Configuration
Calculation uses the free space transmission formula:
                            S = (PG)/(4 πd2)
Where: S is power density (W/m2), P is output power (W), G is antenna gain relative to isotropic, d is separation distance from the
transmitting antenna (m).

Summary of Results

                 Device complies with Power Density requirements at 20cm
                                                                                      No
                                                             separation:
                                  If not, required separation distance (in cm):      27.3
