           F.C.C., Part 15, Subpart C, Section 15.249(a)

  4.2        Test Procedure
          The E.U.T operation mode and test set-up are as described in Section 2 of this
          report.
          The E.U.T was tested in the chamber, and placed on a remote-controlled turntable.
          The E.U.T was placed on a non-metallic table, 1.5 meters above the ground. The
          configuration tested is shown in Figure 2.
          The E.U.T was evaluated in the operation frequency of 915.0MHz.
          The readings were maximized by adjusting the turntable azimuth between 0-360°,
          and the antenna polarization

  5.1    Test Specification
    FCC, Part 15, Subpart C, Section 249(a)

  5.2    Test Procedure
    The E.U.T. operation mode and test set-up are as described in Section 2 of this report.

      The E.U.T was placed in the chamber and placed on a remote-controlled turntable.
      The E.U.T was placed on a non-metallic table, 1.5 meters above the ground. The
      configuration tested is shown in Figure 1.
      The frequency range 1000.0MHz-10,000MHz was scanned. RBW was set to
      1000 kHz. The readings were maximized by adjusting the turntable azimuth between
      0-360°, and the antenna polarization.
      The evaluation distance was 3 meters.

  5.6          Field Strength Calculation
               The field strength is calculated directly by the EMI Receiver software, and a
               "Correction Factors" data disk, using the following equation:

                                  FS = RA + AF + CF



                                       FS:      Field Strength [dBv/m]
                                       RA:      Receiver Amplitude [dBv]
                                       AF:      Receiving Antenna Correction Factor [dB/m]
                                       CF:      Cable Attenuation Factor [dB]

               Example: FS = 30.7 dBV (RA) + 14.0 dB (AF) + 0.9 dB (CF) = 45.6 dBV

                                  No external pre-amplifiers are used.

                                  6.   Radiated Emission
  6.1        Test Specification
        Part 15, Subpart C, Section 15.249(d)

  6.2        Test Procedure
        The E.U.T. operation mode and test set-up are as described in Section 2 of this
        report.
        For measurements between 0.009MHz -30.0MHz:
        The E.U.T was tested inside the shielded room and placed on a non-metallic table,
        1.5 meters above the ground. The frequency range 0.009MHz-30.0MHz was
        scanned. The readings were maximized by the turntable azimuth between 0-360°,
        and the antenna polarization.
        For 30.0MHz-1000.0MHz range:
        A preliminary measurement to characterize the E.U.T was performed inside the
        shielded room at a distance of 3 meters, using peak detection mode and broadband
        antennas. The preliminary measurements produced a list of the highest emissions.
        The E.U.T was then transferred to the open site, and placed on a remote-controlled
        turntable. The E.U.T was placed on a non-metallic table, 0.8 meters above the
        ground. The configuration tested is shown in Figure 1.
        The frequency range 0.009 MHz-1000 MHz was scanned.
        RBW was set to 100 kHz.
        The readings were maximized by adjusting the antenna height between 1-4 meters,
        the turntable azimuth between 0-360°, and the antenna polarization.

        For 1000.0MHz-10,000.0MHz range:
        The E.U.T was placed in the chamber and placed on a remote-controlled turntable.
        The E.U.T was placed on a non-metallic table, 1.5 meters above the ground. The
        configuration tested is shown in Figure 1.
        The frequency range 1000.0MHz-10,000MHz was scanned. RBW was set to
        1000 kHz. The readings were maximized by adjusting the turntable azimuth between
        0-360°, and the antenna polarization.

        For all final evaluations the distance was 3 meters.

  6.3        Test Limits
        Emissions radiated outside of the specified frequency bands, except for harmonics,
        shall be attenuated by at least 50 dB below the level of the fundamental or to the
        general radiated emission limits in §15.209, whichever is the lesser attenuation.

  6.4       Test Results
        JUDGEMENT:              Passed
        The margin between the emission level and the specification limit was 4.5 dB in the
        worst case at the frequency of 64.8 MHz, vertical polarization.
        The EUT met the requirements of the F.C.C. Part 15, Subpart C, Section 15.249
        specification.
