Page 2 of 2 The GM07 transmitter will be used on the GMX222, GMX265, GMX272 and GMT900 vehicles. 1. Frequency The carrier centre frequency is 315MHz. The frequency tolerance is +/-75kHz. 2. Protocol The modulation is Amplitude Shift Keying (ASK). It is Manchester encoding with a 50% duty cycle. 3. Temperature There must be full transmitter operation between -40°C and +85°C. The temperature range must not cause frequency, power and bit width to exceed the limits. The transmitter must be able to withstand an excursion to 125°C for up to 1 hour. Full operation must be restored on return to normal operation temperature range. 4. Operation There are three states for the transmitter – off mode, factory mode and normal mode. The transmitter goes into factory mode from off mode with a LF activation or a pressure delta. The transmitter transmits every 30 seconds in factory mode when motion is detected. After 15 transmissions the transmitter goes into normal mode. Motion is detected using a shock sensor. In normal mode there is a pressure transmission every minute during motion.

Liepa Valdis V. Liepa Research Scientist Summary Tests for compliance with FCC Regulations Part 15, Subpart C, and Industry Canada RSS-210, were performed on Schrader Electronics Limited model(s) 15254101. This device is subject to the Rules and Regulations as a Transmitter. In testing completed on March 21, 2006, the device tested in the worst case met the allowed FCC specifications for radiated emissions by 10.7 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 12 VDC battery.

Introduction Schrader Electronics Limited model 15254101 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 Site facility are on file with FCC Laboratory, Columbia, Maryland (FCC Reg. No: 91050) and with Industry Canada, Ottawa, ON (File Ref.

Configuration and Identification of Device Under Test The DUT is a 315 MHz Tire Pressure Monitor Sensor (transmitter), 1 x 0.25 x 3 inches in size. It operates at 315 MHz and the carrier and is ASK modulated. The transmitter consists of an RF MMIC that is x-tal stabilized. The antenna is the tire pressure stem, and is integral to the device. 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): 15254101 FCC ID: MRXGM07AMSS IC: 2546A- GM07AMSS Both a pulsed and CW mode device were provided. The CW mode device was used for testing because of the slow pulse repetition rate of the pulse device; the fundamental emission for the pulsed device was also measured. Note: The DUT transmits periodically, and can also be activated via LF. It ceases to transmit within 5 seconds of activation. See Figure 6.5. 3.1 Modifications Made There were no modifications made to the DUT by this laboratory. 4. Emission Limits The DUT tested falls under the category of an Intentional Radiators and the Digital Devices. For FCC, it is subject to Part 15, Subpart C, (Section 15.231), Subpart B, (Section 15.109), and Subpart A, (Section 15.33). For Industry Canada it is subject to RSS-210, (Sections 6.1 and 6.3). The applicable testing frequencies with corresponding emission limits are given in Tables 4.1 and 4.2 below. As a digital device, the DUT is considered as a Class B device. 4.1 Radiated …
