Washington Laboratories, Ltd. 7560 Lindbergh Drive Gaithersburg, MD 20879 (301) 417-0220(301) 417-9069 [email protected] D:\Ready_To_Convert\Doc\107141.DOC1 20 June 2000 Andy Leimer Federal Communicatio ns Co mmission 7425 Oakland Mills Road Columbia, MD 21046 RE: OR2AVTRANSTR101 EA96690 Dear Mr. Leimer, Enclosed is an amendment to the above-referenced application. In accordance with the understanding between the FCC, Autovision and Fish & Richardson (representing AutoVision), we have performed radiated emissions measurements of three different vehicles with the subject equipment installed. We have collected data at 22.5 o radials from the three vehicles used for the measurements. These data have been reduced from over 1000 data points to the data set presented in the test report attached hereto. The data show the emissions levels that are within 6 dB of the FCC limit. The frequency range of the transmitter is 88.1 to 89.5 MHz (fixed at the installation of the product in the vehicle), a 1.4 MHz span. Thus, the data presented here were collected for the highest and lowest frequencies in the band. Please review the enclosed report and accompanying photographs and let me know if you have any questions. Sincerely, Michael F. Violette MF V/j m

All measurements herein were performed according to the 1992 version of ANSI C63.4. The measurement equipment conforms to ANSI C63.2 Specifications for Electromagnetic Noise and field Strength Instrumentation. Calibration checks are made periodically to verify proper performance of the measuring instrumentation. All measurements are performed at Washington Laboratories, Ltd. test center in Gaithersburg, MD. Site description and site attenuation data have been placed on file with the FCC's Sampling and Measurements Branch at the FCC laboratory in Columbia, MD. Washington Laboratories, Ltd. has been accepted by the FCC and approved by NIST NVLAP (NVLAP Lab Code: 200066-0) as an independent FCC test laboratory. All results reported herein relate only to the equipment tested. The measurement uncertainty of the data contained herein is ±2.3 dB. Refer to Appendix A for Statement of Measurement Uncertainty. This report shall not be used to claim product endorsement by NVLAP or any agency of the US Government. 1.1Summary After the implementation of the modification listed in Appendix B, the AutoVision Enterprises, Inc. FM Transmitter complies with the limits for an Intentional Radiator under Part 15.239 of the FCC Rules and Regulations. 2.0Description of Equipment Under Test (EUT) The AutoVision Enterprises, Inc. transmitter (EUT) is an FM transmitter used for transmitting audio from a VCR/TV to a vehicle radio so that the audio may be heard over the automobile speakers. The unit transmits at 87.9MHz to 89.5MHz but is factory set to 87.9MHz. 2.1On-board Oscillators The AutoVision Enterprises, Inc. transmitter contains a 16MHz oscillator: AutoVision Enterprises, Inc. FCC ID: OR2AVTRANSTR101 WLL Project #: 5583X 3.0Test Configuration To complete the test configuration required by the FCC, the transmitter was tested in all three orthogonal planes. All testing was performed at 12VDC. I/O PortsI/O Cables Audio Input LShielded (braid), 2m, Audio In Left Audio Input RShielded (braid), 2m, Audio In Right 3.1Testing Algorithm The transmitter was turned on and constantly transmitting. The system was tested in all three orthogonal planes. The transmitter was tested at the lowest, middle and highest frequency of the selectable range. Worst case emissions are recorded in the data tables. 3.2Conducted Emissions Testing Conducted emissions testing was not performed as the unit is DC powered. 3.3Radiated Emissions Testing The EUT was placed on an 80 cm high 1 x 1.5 meters non-conductive motorized turntable for radiated testing on a 3 meter open field test site. The emissions from the EUT were measured continuously at every azimuth by rotating the turntable. Biconical and log periodic broadband antennas were mounted on an antenna mast to determine the height of maximum emissions. The height of the antenna was varied between 1 and 4 meters. The peripherals were placed on the table in accordance with ANSI C63.4-1992. Cables were varied in position to produce maximum emissi…
