1. General Information
   1.1. Product Description:
       The Johnson Controls Interiors HomeLink® HL3 Universal Garage Door Opener is a low-
       power transceiver OEM device that is installed into an overhead console of the
       automobile. The installation is provided by trained technicians during the course of the
       manufacture of the automobile. It is powered by the 12-Volt system of the automobile.

       This Universal Garage Door Opener has the capability to

           1. Learn the frequency and bit code format of the user’s existing garage door remote
             control devices and
           2.Reproduce and transmit the frequency and bit code format to remotely operate the
             user’s garage door.

       The unit is designed for the periodic operation of a control signal, which typically activates
       a garage door opener receiver.

       The unit is supplied to the automobile manufacturer without harness. For testing
       purposes a typical assembly and 2-conductor cable harness were used to power to the
       unit.

       The unit is only operational when the user depresses the control button. It becomes
       inactive after release of the control button.

       The three-button HomeLink® unit replaces up to three hand-held transmitters. In addition
       to the typical operation of the garage door, the unit will learn the radio frequency codes of
       other transmitter types to activate entry door locks, estate gates, security systems, and
       home or office lighting.

       The antenna system is an integral part of the unit. It cannot be altered nor replaced by
       the user. Service of this system is only available from the Automobile Manufacturer’s
       Dealerships and Johnson Controls Interiors, LLC.

        the new settings in the Acura MDX automobile. This report has been submitted in
        addition to the (separate) report for the Acura TL.

    1.3. Test Methodology
        Radiated Emissions testing was done according to ANSI C63.4-2000. The power source
        for this product is a 12V automotive vehicle battery, thus conducted emissions
        measurements are not required.

        Most measurements were performed according to methodology outlined in
        communication with the FCC submitted as miscellaneous exhibit “vehicle_level.pdf”. In all
        cases the guidelines provided by ANSI C63.4-2000 were followed where possible.
        Exceptions are noted if present. Measurements were taken at 10m on the JCI OATS.

        For remaining tests a 2-conductor cable harness was used to supply power to the unit for
        tabletop measurements. Tabletop measurements were taken at 3m on the JCI OATS.

    1.4. Test Facility
        The Open Area Test Site where these measurements were taken, is located on the
        grounds of Johnson Controls Automotive Interiors System’s Edgar D. Prince Technical
        Campus, in the city of Holland, county of Ottawa, state of Michigan, United States of
        America. The site is a fully enclosed 10m weather-protected OATS. All structure
        materials above the conducting ground-plane are non-metallic and consist of: wood,
        laminated lumber, fiberglass, glue, plastic, or fiberglass reinforced plastic. The site
        contains a 15-foot diameter turntable capable of supporting large cars and light trucks
        under test. Tabletop testing was conducted on a smaller 3m turntable described in the
        site recertification report. It has been fully described in a report filled with the FCC and
        Industry Canada. The report filled with the FCC is, dated October 19, 1999, was
        accepted by the FCC in a letter dated December, 20 1999. The report filled with Industry
        Canada, dated January 31, 2000, was accepted via a letter dated February 29, 2000.
        The site was re-certified with the FCC on December 27, 2002 and with the IC on January
        27, 2003.

7. Radiated Emissions Data
   7.1. Summary of Results
                    •   Measurements of the transmit output field strength were taken with the
                        DUT trained to 288, 310, and 418 MHz at 30, 50 and 80% duty cycles. A
                        worst-case average corrected emission of 69.76 dBuV/m occurred
                        with the DUT trained to 310 MHz, 50% duty cycle. The worst-case
                        emission remained slightly below the FCC limit (69.8 dBuV/m) for this
                        type of device.
                    •   Measurements were taken at 340, 365, and 390 MHz in order to
                        evaluate the effect of the changes made in those regions to the limits. A
                        worst-case average emission of 66.6 dBuV/m was measured at 390 MHz
                        presenting a margin of 2.2dB to the FCC limit.
                    •   The worst-case harmonic measurement of 54 dBuV/m was found at
                        836 MHz, the second harmonic of 288 MHz at 30% duty cycle. A margin
                        of 0.3 dB to the prescribed FCC limit was noted.
                    •   This module exhibits pulsed operation characteristics.
                    •   Measurements were taken of the 20dB occupied bandwidth. The
                        transmitter had a maximum occupied bandwidth of 489 kHz when the
                        DUT is trained to 418 MHz, 80% duty cycle.
                    •   This device has no measurable Class B emissions.
                    •   The output power of the DUT varied by no more than 0.2dB when the
                        input voltage was varied from 6 to 18 Volts. The device does not operate
                        when the input voltage is below 8V.

                    •   The device was found to be incapable of operating in restricted bands.
                    •   The device deactivated immediately after the activation button is
                        depressed; less than 5 sec.
                    •   The device uses coarse and fine pulses to tune the transmit antenna. At
                        418 MHz, 30% duty cycle the field strength of the pulses average 4908
                        uV/m over 100 msec. This represents a margin on 9.6 dB to the FCC
                        limit.

                   While in the prescribed orientation, the vertical antenna positioner sweeps in elevation from 1
                   to 4m in height until the operator finds the peak. The 3m turntable is then rotated through 360
                   degrees until a peak is found. The table is stopped at the peak location and the peak in
                   elevation re-verified. Procedure is repeated for applicable orientations/measurement antenna
                   polarizations.

                   For vehicle level measurements, the EUT is fixed in the “flat” position as installed in the
                   vehicle. The antenna positioner is then swept from 1 to 4m at 10m from the center of the
                   vehicle level turntable until the elevation peak is found. The vehicle is then rotated through
                   360 degrees until the azimuth peak is found. The turntable is stopped at the maximum
                   elevation and the peak elevation re-verified.

       7.4.4. Emission Spectrum
              Measurements were taken inside a semi-anechoic chamber to investigate the
              possibility of other spurious emissions from the DUT. Screen captures presented
              below in sections 7.4.4.1-3 show the spurious emissions observed with the DUT
              trained to 288, 310, and 418MHz with a 30% Duty cycle.

              Emissions were noted and measured on the JCI OATS, all measurements were
              found to be near or below the ambient noise level and well below the FCC limits
              for spurious emissions. A summary is presented below in section 7.4.4.4

              Measurement settings:
                    Resolution BW 120kHz
                    Video Bandwidth: 300kHz
                    Detector: Peak

          7.4.6. Verification of Non-Operation in Restricted Bands
                  An exercise was undergone to verify that the device was not able to learn and
                  thereby transmit in a restricted band. During this exercise it was found that the
                  device firmware prevents the device from learning any frequency within 1MHz of
                  any restricted band listed in 47 CFR 15.205.

                                       7.4.8. Tuning Pulse Measurements
                                           This device uses pulses to tune the antenna prior to transmission. Measurements of
                                           these tuning pulses over 100msec windows show that these pulses are below the
                                           FCC limits for operation in this band. A summary of measurements is presented in
                                           section 7.4.8.7. Tuning pulse measurements were taken at 288, 310, and 418 MHz
                                           at a duty cycle of 30%.

   7.5. Formulas and Sample Calculations
       7.5.1. Adjustment to account for duty cycle
         The spectrum analyzers used for making the measurements in this report automatically
         corrects for cable correction and antenna factors using values stored in memory taken
         from the most recent calibration (in the case of antenna factors) and periodic cable loss
         measurements.

         Formula 1:  FS(dBuV/m) = M(dBuV) + AF(dB/m) + CF(dB)
         The presented field strength is computed by the spectrum analyzer by taking the
         measured level and adding to it the antenna factor and cable loss corrections. The
         measurement presented in gathered using the spectrum analyzer’s peak-hold
         capability.

         Formula 2: Average Level(dBuV/m) = Peak Level (dBuV/m) + duty cycle factor(dB).
         The peak measurement is adjusted to an average level by a duty cycle described
         below.

         The duty cycle factor to apply is determined for the duty cycles of 30%, 50%, and 80%
         as follows:
                For 30% (0.30):         duty cycle factor(dB) = 20*Log(0.3) = -10.46
                For 50% (0.50):         duty cycle factor(dB) = 20*Log(0.5) = -6.02
                For 80% (0.80):         duty cycle factor(dB) = 20*Log(0.8) = -1.94

         Example calculation:
          With the EUT programmed with a 30% duty cycle a measurement of 74 dBuV/m is
         taken (about 5000 uV/m), the adjusted level would be:
                              74 + (-10.46) = 63.54 dBuV/m (example)

       7.5.2.   Calculation of FCC limits from 15.231.

       The prescribed limit in the range of 260 MHz to 470 MHz is stated as a linear
       interpolation between 3750 uV/m and 12500 uV/m. The equation used to calculate the
       limit using this criteria is:

                FCC limit = 41.67 * f – 7083.33
                (Where ‘f’ is the measurement frequency in MHz.)

       The limit is dBuV/m is then:

               dB limit = 20 * log10( FCC limit uV/m) = 20*log10( 41.67*f – 7083.33)
               ( log10 is used to indicated the use of a base 10 logarithm)

       This results in the following limits for the fundamentals:

     288MHz                  20*log10(4917.6) = 73.8 dBuV/m
     310MHz                  20*log10(5834.4) = 75.3 dBuV/m
     390MHz                  20*log10(9168.0) = 79.2 dBuV/m
     418MHz                  20*log10(10334.7) = 80.3 dBuV/
 NOTE: An adjustment of 10.45dB is used to adapt limits for 10m measurements.
