The sensor transmits periodically measurements of pressure and temperature using an integrated RF transmitter to a compatible receiver embedded in the vehicle to provide continuous information of the individual pressure of each wheel to the driver. The wheel unit sensor invorporates a pressure alarm function, which transmits an alarm message when the sensor detects under-inflation of at least 15% over a maximum period of one minute. Number of tested samples: 2 Serial number: Sample ID F008D03F Sample ID F008CdE2 EUT operation mode: The equipment under test was operated during the measurement under the following conditions: - Tx mode at frequency 315 MHz, Fast send mode (Alarm mode) - Tx mode at frequency 315 MHz, Normal Operation mode - EUT configuration: (The CDF filled by the applicant can be viewed at the test laboratory.)

No. 1.1, 05.11.2008 5.2 Field strength of the fundamental wave For test instruments and accessories used see section 6 Part CPR 2. 5.2.1 Description of the test location Test location: OATS1 Test distance: 3 metres 5.2.2 Photo documentation of the test set-up 5.2.1 Applicable standard According to FCC Part 15C, Section 15.231(e): The field strength of emissions from intentional radiators shall not exceed the effective field strength limits. 5.2.2 Description of Measurement The radiated power of the fundamental wave from the EUT is measured in the frequency range of 30 to 1000 MHz using a tuned receiver and appropriate broadband linearly polarized antennas. Measurements between 30 MHz and 1000 MHz are made with 120 kHz/6 dB bandwidth and quasi-peak detection. Table top equipment is placed on a 1.0 X 1.5 metres non-conducting table 80 centimetres above the ground plane. Floor standing equipment is placed directly on the turntable/ground plane. The set up of the EUT will be in accordance to ANSI C63.4. The Interface cables that are closer than 40 centimetres to the ground plane are bundled in the centre in a serpentine fashion so they are at least 40 centimetres from the ground plane. Cables to simulators/testers (if used in this test) are routed through the centre of the table and to a screen room located outside the test area. The antenna was positioned 3, 10 or 30 metres horizontally from the EUT. To locate maximum emissions from the test sample the antenna is varied in height from 1 to 4 metres, measurement scans are made in horizontal and vertical antenna polarization’s and the EUT is rotated 360 degrees. The resolution bandwidth during the measurement is as follows: FCC ID: YMY030152 mikes-testingpartners gmbh File No. T34706-00-00HU, page 12 of 28 Ohmstrasse 2-4 x 94342 STRASSKIRCHEN x GERMANY Tel.:+49(0)9424-94810 x Fax: +49(0)9424-9481240 Rev. No. 1.1, 05.11.2008 5.3 Spurious emissions (magnetic field) 9 kHz – 30 MHz For test instruments and accessories used see section 6 Part SER 1. 5.3.1 Description of the test location Test location: OATS1 Test distance: 3 metres 5.3.2 Photo documentation of the test set-up 5.3.3 Applicable standard According to FCC Part 15C, Section 15.209: The emissions from intentional radiators shall not exceed the effective field strength limits. 5.3.4 Description of Measurement The magnetic field strength from the EUT will be measured on an open area test site in the frequency range of 9 kHz to 30 MHz using a tuned receiver and a shielded loop antenna. The set up of the Equipment under test will be in accordance to ANSI C63.4. The antenna was positioned 3, 10 or 30 meters horizontally from the EUT. Measurements have been made in all three orthogonal axes and the shielded loop antenna was rotated to locate the maximum of the emissions. In the case where larger measuring distances are required the results will extrapolated based on the values measured on the closer distances according to Section 15.31(f)(2)(2). The final measurement will be performed with an EMI Receiver set to Quasi Peak detector except for the frequency bands 9 kHz to 90 kHz and 110 to 490 kHz where an average detector will be used according to Section 15.209(d)(2).
