             The device described above is tested by ACCURATE TECHNOLOGY CO. LTD to determine
             the maximum emission levels emanating from the device. The maximum emission levels are
             compared to the FCC Part 15 Subpart C Section 15.227 limits. The measurement results are
             contained in this test report and ACCURATE TECHNOLOGY CO. LTD is assumed full
             responsibility for the accuracy and completeness of these measurements. Also, this report shows
             that the Equipment Under Test (EUT) is to be technically compliant with the FCC requirements.

                  3.3.Configuration of EUT on Measurement
                     The following equipment are installed on Radiated Emission Measurement to meet the
                     commission requirements and operating regulations in a manner which tends to maximize
                     its emission characteristics in normal application.

                  3.4.Operating Condition of EUT
                        3.4.1.Setup the EUT and simulator as shown as Section 3.1.

                        3.4.2.Turn on the power of all equipment.

                        3.4.3. Let the EUT work in TX modes(on) measure it.


                  3.5.Test Procedure
                     The EUT and its simulators are placed on a turntable, which is 0.8 meter high above
                     ground. The turntable can rotate 360 degrees to determine the position of the maximum
                     emission level. EUT is set 3.0 meters away from the receiving antenna, which is mounted
                     on an antenna tower. The antenna can be moved up and down between 1.0 meter and 4
                     meters to find out the maximum emission level. Broadband antenna (calibrated bilog
                     antenna) is used as receiving antenna. Both horizontal and vertical polarizations of the
                     antenna are set on measurement. In order to find the maximum emission levels, all of the
                     interface cables must be manipulated according to FCC Part 15 Subpart C on radiated
                     emission measurement.

                     The bandwidth of test receiver (R&S ESI26) is set at 120KHz in 30-1000MHz.
                     The frequency range from 30MHz to 1000MHz is checked.

                      The final measurement in band 9-90kHz, 110-490kHz and above 1000MHz is performed
                      with Average detector. Except those frequency bands mention above, the final
                      measurement for frequencies below 1000MHz is performed with Quasi Peak detector.

     The spectral diagrams in appendix 1 display the measurement of un-weighted peak values.
         The field strength is calculated by adding the antenna factor, high pass filter loss(if used) and cable loss, and
subtracting the amplifier gain(if any)from the measured reading. The basic equation calculation is as follows:
            Result = Reading + Corrected Factor
       Where Corrected Factor = Antenna Factor + Cable Loss + High Pass Filter Loss – Amplifier Gain
