Re: Certification for Schrader Transmitter FCC ID: MRXFS5MAF4 IC: 2546A-FS5MAF4 REQUEST FOR CONFIDENTIALITY Pursuant to FCC 47 CRF 0.457(d) and 0.459 and IC RSP-100, Section 10, Schrader requests that a part of the subject application be held confidential. Schrader has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship.

Description of operation: The TPM sensor / transmitter is a self-contained unit in which there are no electrical connections into or out of the device. The unit monitors and transmits tire cavity pressure and Temperature using an RF signal to a receiver unit. Each TPM sensor contains a unique ID code in its transmission data that a receiver can use to identify tire position or illuminate a warning lamp that identifies that one or more tires has a pressure out of range event.

Brunett Research Scientist Summary Tests for compliance with FCC Regulations, CFR 47, Part 15 and with Industry Canada RSS-210/Gen, were performed on a Schrader, FCC ID: MRXFS5MAF4, IC: 2546A-FS5MAF4. This device under test (DUT) is subject to the rules and regulations as a Transmitter. In testing completed on March 31, 2010, the DUT tested met the allowed specifications for radiated emissions by 4.7 dB. Conducted emissions are not subject to regulation as the DUT is powered by a 3 VDC battery.

Introduction This Schrader transmitter 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 7, June 2007. 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 Site facility are on file with FCC Laboratory, Columbia, Maryland (FCC Reg. No: 91050) and with Industry Canada, Ottawa, ON (File Ref. No: IC 2057A-1). 2. Equipment Used The test equipment commonly used in our facility is listed in Table 2.1. Except where indicated as a pre- test, monitoring, or support device; all equipment listed below is a part of the University of Michigan Radiation Laboratory (UMRL) quality system. This quality system has been established to ensure all equipment has a clearly identifiable classification, calibration expiry date, and that all calibrations are traceable to national standards.
