Liepa Report approved by: _____________________ Valdis V. Liepa Test Report Prepared by: Joseph D. Brunett Research Scientist Summary Tests for compliance with FCC Regulations Part 15, Subpart C, and Industry Canada RSS-210/GEN, were performed on Schrader Electronics Limited model(s) MRXDCA315TX1. This device is subject to the Rules and Regulations as a Transmitter. In testing completed on May 17, 2006, the device tested in the worst case met the allowed FCC specifications for radiated emissions by 6.0 dB (see p. 6). Besides harmonics, there were no other significant spurious emissions found; emissions from digital circuitry were negligible. The conducted emission tests do not apply, since the device is powered from a 3 VDC battery.

Introduction Schrader Electronics Limited model MRXDCA315TX1 was tested for compliance with FCC Regulations, Part 15, adopted under Docket 87-389, April 18, 1989 as subsequently amended, and with Industry Canada RSS-210/Gen, Issue 6, September 2005. The tests were performed at the University of Michigan Radiation Laboratory Willow Run Test Range following the procedures described in ANSI C63.4-2003 "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 Area Tes Site are on file with FCC Laboratory, Columbia, Maryland (FCC Reg. No: 91050) and with Industry Canada, Ottawa, ON (File Ref. No: IC 2057). 2. 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 (DUT) 3.1 Design and Identification of the Device The DUT is a 2 x 0.75 x 2.5 inches in size (including valve stem), potted tire pressure transmitter. The 315 MHz carrier is generated by an RFIC stabilized using a 9.84375MHz crystal. The device transmits FSK data with 82 kHz modulation. The DUT was designed and manufactured by Schrader Electronics Limited, 11, Technology Park, Belfast Road,, Antrim BT41 1QS, Northern Ireland. It is identified as: Schrader Electronics TPMS Transmitter Model(s): MRXDCA315TX1 FCC ID: MRXDCA315TX1 IC: 2546A-DCATX1 3.2 Models There is only one model of the DUT. Two versions were provided; one capable of CW transmission and one standard module that could be LF actuated. The CW version was used to measure harmonic emissions, all other tests were performed on the pulsed module. 3.3 Modes of Operation The DUT periodically transmits tire pressure data. The device is also capable of being automatically actuated (via LF interrogation) either by in-vehicle LF initiators or by trained personnel during servicing. Per FCC correspondence, service modes fall under FCC part 15.231(a)(5). Figure 6.1 demonstrates compliance with both 15.231(a)(2) and (5). A list of all operating modes is included in the Description of Operation exhibit. 3.4 EMI/EMC Relevant Modifications There were no modifications made to the DUT by this laboratory. 4. Regulatory Limits The DUT tested falls under the …
