Courtney Valdis V. Liepa Research Scientist Summary Tests for compliance with FCC Regulations Part 15, Subpart B, and Industry Canada RSS-210, were performed on Lear Corporation model FR04U204. This device is subject to the Rules and Regulations as a Receiver. As a Digital Device it is exempt, but such measurements were made to assess the receiver's overall emissions. In testing completed on 30-Jun-03, the device tested in the worst case met the allowed FCC (Class B) specifications for radiated emissions by 19.9 dB (see p. 6). The conducted emissions tests do not apply, since the device is powered from a 12 VDC system. 2 1. Introduction Lear Corporation model FR04U204 was tested for compliance with FCC Regulations, Part 15, adopted under Docket 87-389, April 18, 1989, and with Industry Canada RSS-210, Issue 5, November, 2001. The tests were performed at the University of Michigan Radiation Laboratory Willow Run Test Range following the procedures described in ANSI C63.4-1992 "Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz". The Site description and attenuation characteristics of the Open Site facility are on file with FCC Laboratory, Columbia, Maryland (FCC Reg. No: 91050) and with Industry Canada, Ottawa, ON (File Ref. No: IC 2057). 2. Test Procedure and Equipment Used The pertinent test equipment commonly used in our facility for measurements is listed in Table 2.1 below.

Configuration and Identification of Device Under Test The DUT is a 315 MHz superheterodyne receiver, designed for onboard automobile security/convenience applications, and as such, it is powered from an automotive 12 VDC source. It is housed in a plastic case approximately 6 by 8 by 1.5 inches. Antenna is internal. For testing, a generic and load box was provided by the manufacturer. In the receiver digital section, the decoding, signal processing, etc. are performed by a microprocessor timed by an 4.0 MHz oscillator. The DUT was designed and manufactured by Lear Corporation,5200 Auto Club Drive,Dearborn, MI 48126. It is identified as: Lear Corporation Receiver Model: FR04U204 S/N or P/N: NATT035 FCC ID: KOBFR04U204 IC: 3521A-FR04U204 3.1 Modifications Made There were no modifications made to the DUT by this laboratory. 4. Emission Limits The DUT tested falls under Part 15, Subpart B, "Unintentional Radiators". The pertinent test frequencies, with corresponding emission limits, are given in Tables 4.1 and 4.2 below. 4.1 Radiated Emission Limits Table 4.1. Radiated Emission Limits (Ref: 15.33, 15.35, and 15.109). Freq. (MHz) E lim (3m) μV/m E lim dB(μV/m) 30-88 100 40.0 88-216 150 43.5 216-960 200 46.0 960-2000 500 54.0 Note: Quasi-Peak readings apply to 1000 MHz (120 kHz BW) Average readings apply above 1000 MHz (1 MHz BW) 4.2 Conducted Emission Limits Table 4.2. Conducted Emission Limits (Ref: 15.107). Freq. (MHz) μV dB(μV) 0.450 - 1.705 250 48.0 1.705 - 30.0 250 48.0 Note: Quasi-Peak readings apply here 4 4.3 Antenna Power Conduction Limits Ref: 15.111(a). Pmax = 2 nW; for frequency range see Table 4.1. 5. Emission Tests and Results NOTE: Even though the FCC and/or Industry Canada specify that both the radiated and conductive emissions be measured using the Quasi-Peak and/or average detection schemes, we normally use peak detection since especially the Quasi-Peak is cumbersome to use with our instrumentation. In case the measurement fails to meet the limits, or the measurement is…
