Date of Issue: October 18, 2011 Prepared For: Schrader Electronics Test Report No.: 20111018-01 2 Configuration and Identification of the Equipment Under Test 2.1 Description and Declarations The EUT is a wireless tire pressure and temperature sensor. The equipment under test (EUT) is approximately 6 x 3 x 2 cm (without stem) in dimension, and is depicted in Figure 1. It is powered by a 3 VDC Lithium cell battery. In use, this device is permanently affixed as the valve-stem in the tire of a motor vehicle. Table 2 outlines provider declared Figure 1: Photographs of the EUT. EUT specifications. Table 2: EUT Declarations. General Declarations Equipment Type: TPMS Country of Origin: UK Nominal Supply: 3 VDC Oper. Temp Range: −40o C to +85o C Frequency Range: 433.9 MHz Antenna Dimension: 46 mm Antenna Type: Tire Stem (monopole) Antenna Gain: -5 dBi (declared) Number of Channels: One (1) Channel Spacing: Not Applicable Alignment Range: ±0.1 MHz Type of Modulation: ASK United States FCC ID Number: MRXGMG2R4AM Classification: DSC Canada Remote Control De- IC Number: 2546A-GMG2R4AM Classification: vice, Vehicular Device 2.1.1 EUT Configuration The EUT is configured for testing as depicted in Figure 2. 2.1.2 Modes of Operation The EUT is capable of three key modes of operation. Upon manually activated LF interrogation (through the use of special LF tool at a vehicle dealership), the EUT responds with a singe transmission containing a number of frames used to configure the device with the vehicle. When the EUT is placed in the vehicle tire and the vehicle drives, it can, in the worst case, periodically transmit where the duration of each transmission is always less than 1 second and the silent period between transmissions is at least 30 times the duration of the transmission, and never less than 10 seconds. In the case of an emergency condition, the EUT will transmit tire pressure and temperature information throughout the duration of the condition.

Normal samples were actuated for worst case on time, worst case emission bandwidth, and CW mode. Please see the description of operation exhibit supplied with this filing detailing the operating modes of this device. 2.1.4 Test Samples Three samples in total were provided. Two normal samples capable of normal, test, and CW mode activation. One sample un-potted for testing and photographs. 2.1.5 Functional Exerciser Not Applicable. 2.1.6 Modifications Made There were no modifications made to the EUT by this laboratory. 2.1.7 Production Intent The EUT appears to be a production ready sample. 2.1.8 Declared Exemptions and Additional Product Notes The EUT is permanently installed in a transportation vehicle. As such, digital emissions are exempt from US and Canadian digital emissions regulations (per FCC 15.103(a) and IC correspondence on ICES-003). The EUT also employs some modes of operation that alert the vehicle user of sudden changes in tire pressure. Such alert modes fall under FCC 15.231(a)(4), and may operate during the pendency of the alarm condition. A detailed list of all operating modes is included in the Description of Operation exhibit included in this application.

Date of Issue: October 18, 2011 Prepared For: Schrader Electronics Test Report No.: 20111018-01 3 Emissions 3.1 General Test Procedures 3.1.1 Radiated Test Setup and Procedures Radiated electromagnetic emissions from the EUT are first evaluated in our shielded fully anechoic chamber. Spec- trum and modulation characteristics of all emissions are recorded, and emissions above 1 GHz are fully characterized. The anechoic chamber contains a set-up similar to that of our outdoor 3-meter site, with a turntable and antenna mast. Instrumentation, including spectrum analyzers and other test equipment as detailed in Section 1.2 are em- ployed. After indoor pre-scans, emission measurements up to 1 GHz are made on our outdoor 3-meter Open Area Test Site (OATS). If the EUT connects to auxiliary equipment and is table or floor standing, the configurations prescribed in ANSI C63.4 / CISPR 22 are followed. Alternatively, a layout closest to normal use (as declared by the provider) is employed if the resulting emissions appear to be worst-case in such a configuration. See Figure 3. Long Interface Cables EUT Power Long Interface Cables (to AUX) AUX Power (to EUT) Equipment Under Test Auxiliary (EUT) Short Interface Cables Equipment (AUX) Radiated Emissions Table Figure 3: Radiated Emissions Diagram of the EUT. All intentionally radiating elements are placed on the test table lying flat, on their side, and on their end (3-axes) and the resulting worst case emissions are recorded. For both horizontal and vertical polarizations, the test antenna is raised and lowered from 1 to 4 m in height until a maximum emission level is detected. The EUT is then rotated through 360o in azimuth until the highest emission is detected. The test antenna is then raised and lowered one last time from 1 to 4 m and the worst case value is recorded. If the EUT exhibits spurious emissions due to internal receiver circuitry, such emissions are measured with an appropriate carrier signal applied. For devices with intentional emissions below 30 MHz, a shielded loop antenna is used as the test antenna. It is placed at a 1 meter receive height and appropriate low frequency magnetic field extrapolation to the regulatory limit distance is employed. Emissions between 30 MHz and 1 GHz are measured using tuned dipoles and/or calibrated broadband antennas. Emissions above 1 GHz are characterized using standard gain horn antennas. Care is taken to ensure that test receiver resolution and video bandwidths meet the regulatory requirements, and that the emission bandwidth of the EUT is not reduced. Photographs of the test setup employed are depicted in Figure 4. Willow Run Test Labs, LLC, 8501 Beck Rd., Bldg 2227, Belleville, MI 48111 Page 7 of 14

Date of Issue: October 18, 2011 Prepared For: Schrader Electronics Test Report No.: 20111018-01 3.1.2 Conducted Test Setup and Procedures Battery Power Conducted Spurious The EUT is not subject to power line conducted emissions measurements when it is powered solely by its internal battery. 3.1.3 Power Supply Variation Tests at extreme supply voltages are made if required by the the procedures specified in the test standard, and results of this testing are detailed in this report. DC Extreme Voltages If the EUT is designed for operation from a lead-acid battery power source, the extreme test voltages are evaluated between 90% and 130% of the nominal battery voltage declared by the manufacturer. For float charge applications using gel-cell type batteries, extreme test voltages are evaluated between 85% and 115% of the nominal battery voltage declared. For all battery operated equipment, worst case intentional and spurious emissions are re-checked employing a new (fully charged) battery. 3.1.4 Thermal Variation Tests at extreme temperatures are made if required by the procedures specified in the test standard, and results of this testing are detailed in this report. The provider has declared that the EUT is designed for operation over the temperature range −40o C to +85o C. Before any temperature measurements are made, the equipment is allowed to reach a thermal balance in the test chamber, temperature and humidity are recorded, and thermal balance is verified via a thermocouple based probe.

Date of Issue: October 18, 2011 Prepared For: Schrader Electronics Test Report No.: 20111018-01 3.2.2 Fundamental Emission Bandwidth Emission bandwidth (EBW) of the EUT is measured with the device placed in the test mode(s) with the shortest available frame length and minimum frame spacing. Radiated emissions are recorded following the test procedures listed in Section 1.1. The 20 dB EBW is measured as the max-held peak-detected signal when the IF bandwidth is greater than or equal to 1% of the receiver span. For complex modulations other than ASK and FSK, the 99% emission bandwidth per IC test procedures has a different result, and is also separately reported.The results of EBW testing are summarized in Table 4. Plots showing measurements employed to obtain the emission bandwidth reported are provided in Figure 6. Table 4: Intentional Emission Bandwidth.
