Re: Certification for Schrader Receiver FCC ID: MRXC2A4MA4 IC: 2546A-C2A4MA4 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.

Page 1 of 2 Technical Description of the FF TPMS (Tire Pressure Monitoring System) ECU Brief Description A block diagram of the ECU is shown in figure 1. The ECU (Electronic Control Unit) has the following sections: - RF circuit - CAN tranceiver - Microprocessor - Power Section including Decoupling The system has been developed to monitor a vehicle's tyre pressure s. An electronic unit inside ea ch tyre, (referred to as the T PMS transmitter) mounted to the valve stem, periodically measures act ual tyre pressure. By means of RF communication, this pressure information is transmitted to the ECU (receiver) which is fitted in the car. The ECU filters this RF in the RF section and deco des the pressure informatio n via the microprocessor. The Power Decoupling section is used to protect the ECU against transients etc on the VBat ECU inputs. The CAN section is an interface unit for the CAN bus on the car and out ECU.

Liepa Report Approved by:__________________________ Valdis V. Liepa Test report written by: Joseph D. 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: MRXC2A4MA4, IC: 2546A-C2A4MA4. This device under test (DUT) is subject to the rules and regulations as a Receiver. In testing completed on November 10, 2010, the DUT tested met the allowed specifications for radiated emissions by more than 7.9 dB. Conducted emissions are not subject to regulation as the DUT is powered by a 12 VDC battery.
