      EUT SETUP

      The equipment under test (EUT) listed was setup in a manner that represented its normal use.
      Any special conditions required for the EUT to operate normally are identified in the comments
      that accompany Tables 1 for fundamental field strength emissions, Tables 2 & 3 for radiated
      emissions.

      During radiated emissions testing, the EUT was mounted on a nonconductive, rotating table 1
      meter above the conductive grid. The nonconductive table dimensions were 1 meter by 1.5
      meters. This configuration is typical for radiated emissions testing of table top devices.


      TEST INSTRUMENTATION AND ANALYZER SETTINGS

      The test instrumentation and equipment listed in Table A were used to collect both the radiated
     and conducted emissions data for the ActiMates Arthur, ActiMates DW.                For radiated
     measurements below 30 MHz, the mag loop antenna was used. For radiated measurements
     between 30 MHz — 300 MHz, the biconical antenna was used. For frequencies from 300 to 1000
     MHz, the log periodic antenna was used. For antenna locations please refer to Tables 1—3 or the
     test data sheets contained in Appendix B.

     The HP spectrum analyzer was used for all measurements. Table B shows the analyzer
     bandwidth settings that were used in designated frequency bands. During radiated testing, the
     measurements were made with 0 dB of attenuation, a reference level of 97 dBuV, and a vertical
     scale of 10 dB per division.

      SPECTRUM ANALYZER DETECTOR FUNCTIONS

      The notes that accompany the measurements contained in Tables 1, 2 and 3 indicate the type of
     detector function used to obtain the given readings. Unless otherwise noted, all readings were
     made in the "Peak" mode. Whenever a "Quasi—Peak" or "Average" reading is listed as one of the
     six highest readings, this is indicated as a "Q" or an "A" in Table 1, Table 2 or Table 3. The
     following paragraphs describe in more detail the detector functions and when they were used to
     obtain the emissions data for the ActiMates Arthur, ActiMates DW.

     Peak

     In this mode, the Spectrum Analyzer or test engineer recorded all emissions at their peak value
     as the frequency band selected was scanned. By combining this function with another feature of
     the analyzer called "peak hold," the analyzer had the ability to measure transients or low duty
     cycle transient emission peak levels. In this mode the analyzer made a slow scan across the
     frequency band selected and measured the peak emission value found at each frequency across
     the band.

     Quasi—Peak

     When the true peak values exceeded or were within 2 dB of the specification limit, quasi—peak
     measurements were taken using the HP 85650A Quasi—Peak Adapter for the HP 8568B Spectrum
     Analyzer. The detailed procedure for making quasi peak measurements contained in the HP
     Quasi—Peak Adapter manual were followed.

     Average


     When the frequencies exceed 1 GHz, average measurements may be made using the spectrum
     analyzer. To make these measurements, the test engineer reduces the video bandwidth on the
     analyzer until the modulation of the signal is filtered out. At this point the analyzer is set into the
     linear mode and the scan time is reduced.




                                                                                                Page 12 of 25

      TEST METHODS

      The radiated emissions data of the ActiMates Arthur, ActiMates DWwas taken with the HP
      Spectrum Analyzer. Incorporating the applicable correction factors for distance, antenna, cable
      loss and amplifier gain, the data was reduced as shown in the "Sample Calculations". The
      corrected data was then compared to the FCC Part 15, Subpart C emissions limits to determine
      compliance.

      Preliminary and final measurements were taken in order to better ensure that all emissions from
      the EUT were found and maximized.

      Radiated Emissions Testing

     During the preliminary radiated scan, the EUT was powered up and operating in its defined FCC
     test mode facing the antenna. The frequency range of 9 kHz — 30 MHz was scanned with the
     mag loop antenna. The frequency range of 30 MHz — 88 MHz was then scanned with the
     biconical antenna located about 1.5 meter above the ground plane in the vertical configuration.
     During this scan, the turntable was rotated and all peaks which were at or near the limit were
     recorded. The frequency range of 100 — 300 MHz was scanned with the biconical antenna in the
     same manner, and the peaks recorded. Lastly, a scan of the FM band from 88 — 110 MHz was
     made, using a reduced resolution bandwidth and a reduced frequency span. The biconical
     antenna was changed to the horizontal polarity and the above steps were repeated. After
     changing to the log periodic antenna in the horizontal configuration, the frequency range of 300 —
     1000 MHz was scanned. The log periodic antenna was changed to the vertical polarity and the
     frequency range of 300 — 1000 MHz was again scanned. Care was taken to ensure that no
     frequencies were missed within the FM and TV bands. An analysis was performed to determine
     if the signais that were at or near the limit were caused by an ambient transmission. If unable to
     determine by analysis, the equipment was powered down to make the final determination if the
     EUT was the source of the emission.

     For the final radiated scan, the equipment was again positioned facing the antenna. A thorough
     scan of all frequencies was manually made using a small frequency span, rotating the turntable as
     needed. Comparison with the previously recorded measurements was then made.

     Using the peak readings from both scans as a guide, the test engineer then maximized the
     readings with respect to the table rotation and antenna height. Maximizing of the EUT was
     achieved by monitoring the spectrum analyzer on a closed circuit television monitor while the
     EUT was being moved and rearranged on the EUT table for maximum emissions. Photographs
     showing the final worst case configuration of the EUT are contained in Appendix A.

         FCC Part 15.31(e) — Frequency Stability Measurements

         In accordance with Part 15.31(e), since the unit was battery operated, a fresh battery was
        inserted.

        Frequency Range of Transmitter: 49.860 MHz

        In accordance with Part 15.235(a), the field strength of the emissions within the 49.82—49.90
        MHz band did not exceed 10,000 microvolts/meter at 3 meters. The emission limit in was based
        on the measurement instrumentation employing an average detector. The provisions in 15.35 for
        limiting peak emissions apply.


        FCC Part 15.235— Occupied Bandwidth Measurements

        In accordance with Part 15.235(b), the field strength of the emissions between the band edges
        and up to 10 kHz above and below the band edges were attenuated 26 dB below the level of the
        unmodulated carrier. The field strength of the emissions removed by more than 10 kHz from the
        band edges did not exceed the general radiated emission limits in 15.209. Please refer to the
        occupied bandwidth plots for test results.

        SAMPLE CALCULATIONS

       The basic spectrum analyzer reading was converted using correction factors as shown in the six
       highest emissions readings in Tables 1, 2 and 3. For radiated emissions in dBuV/m, the
       spectrum analyzer reading in dBuV was corrected by using the following formula:

                       Meter reading (dBuV)
                       + Antenna Factor (dB)
                       + Cable Loss (dB)
                       — Distance Correction (dB)
                       — Pre—amplifier Gain (dB)

                       = Corrected Reading(dBuV/m)

       This reading was then compared to the applicable specification limit to determine compliance.

       Freq MHz is the frequency in MHz of the obtained reading.
       Rdng dBuV is the reading obtained on the spectrum analyzer in dBuV.
       Amp. is short for the preamplifier factor or gain in dB.
       Magne is the mag loop antenna factor in dB.
       Site is the biconical antenna factor in dB.
       Log B is the log periodic antenna factor in dB.
       Cable is the cable loss in dB of the coaxial cable on the OATS.
       Dist is the distance factor (in dB). It is used when testing at a different test distance than the one
       stated in the spec.
       Corr dBuV/m is the corrected reading which is now in dBuV/m (field strength).
       Spec is the specification limit (dB) stated in the agency‘s regulations.
       Margin is the closeness to the specified limit in dB; + is over and — is under the limit.
       Polar is the Polarity of the antenna with respect to earth.
