No. 3.0, 2014-01-30 2 S U M M A R Y GENERAL REMARKS: All radiated tests have been performed on samples which are in original state. For activating the EuT a “Pressure Vessel” was used to power up the Wheel Unit Sensor in the different operation modes. The EuT has an incorporated antenna and is powered by a primary battery. For testing the manufacturer declares following transmitting intervals: Each wheel electronic has its own code (ID) that is transmitted with the datagram at each transmission event. The RF transfer occurs in the 315MHz or 433.92 MHz range. The samples are in standstill mode. For activating the EUT it has to be put into the pressure box where it is possible to change the pressure. - Storage mode (mode 0): In storage mode no RF transmission takes place. - Normal mode (mode 1) @ standstill and rotating: In normal mode, the wheel electronics measure the tire pressure and the approximate temperature of the air in the tire every three seconds but if the measured values are stable, RF transmitting processes only every 54 seconds. - The alarm mode can be activated by the use of a pressure box. The pressure has to be set to 2 bar for 5 minutes. Now the sensor switches into normal mode. - Alarm mode (mode 2) @ pressure loss: When a pressure loss > 0.2 bar on the last sent pressure value is detected, the wheel electronics switch immediately to alarm mode. In this situation, the wheel electronics measure and send every 1 seconds a RF datagram for 255 seconds. After this time it falls back to the normal mode. The alarm mode can be activated by the use of a pressure box. The pressure in the box has to be set to 2 bar. Now the sensor switches for about 4 minutes into alarm mode. Then a rapid pressure drop of at least 0.2 bar must be generated again so that the alarm mode will continue. Pulse duration for normal and alarm mode = 10.1 ms (+/-0.2 ms) FCC ID: OYGTSSRE4PC CSA Group Bayern GmbH File No. T37830-00-04HU, page 5 of 33 Ohmstrasse 1-4  94342 STRASSKIRCHEN  GERMANY Tel.:+49(0)9424-94810  Fax: +49(0)9424-9481440 Rev.

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 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).
