The TPM Sensor is intended to interface to a receiver/decoder that has been designed to accept the TPM sensor protocol. The TPM Sensor is designed to monitor a vehicle's tyre pressure whilst driving or stationary. An electronic unit inside each tyre (referred to as the TPM Sensor or TPM transmitter) mounted to the valve stem, periodically measures actual tyre pressure/temperature. This pressure information is transmitted to a receiver/decoder by means of an RF link. The incoming radio frequency signals are decoded, and the data used to inform the driver of the tyre pressure information via the vehicles TPM interface. TPM Sensor main functions are: • Regularly measure the tyre pressure. • Monitor if the wheel is moving. • Periodically transmit tyre pressure using an RF link and a specific protocol. • Notify the system if there are abnormal pressure variations (leak) in the tyre. • Monitor the transponder input for valid LF field

Schrader Electronics Ltd Unit 11 Technology Park Belfast Road Antrim, Northern Ireland, BT41 1QS Dear sir/madam, Model names: AHMPD4 and ATAPC4 Please be aware that the Antenna in both the above Models is named as being an Integral Antenna, in fact these are trace Antenna’s. The photographs are listed as being confidential in the application as the circuit board or internal components are not accessible to users. These parts are Tyre Pressure Monitoring sensors and are mounted on the inside of a tyre rim. They are also coated in epoxy and would be damaged if the epoxy was removed. I hope that these clarifications are sufficient. Regard and thanks Zoe Gourley Product Compliance Administrator http://www.tpmseuroshop.com/documents/declaration_conformities

The duty cycle test was performed on a sample of EUT programmed to operate at the highest duty cycle possible. Environmental conditions During the measurement the environmental conditions were within the listed ranges: Normal Temperature: +15 to +35 ° C Humidity: 20-75 % 1.2 Modifications No modifications were required in order to pass the test specifications. 1.3 Date of Test The tests were carried out on one sample of the EUT on 26 th and 27 th of Nov 2019 and 23 rd Jan 2020. 1.4 Electromagnetic Emissions Testing The guidelines of CISPR 16-4 were used for all uncertainty calculations, estimates and expressions thereof for EMC testing. A copy of Compliance Engineering Ireland Ltd.’s policy for EMC Measurement Uncertainty is available on request. RF Requirements: Spurious emissions in accordance with FCC CFR 15.107, 15.109 and 15.209. Tests were carried out to the requirements of CISPR 16-4 and ANSI C63.4-2014 and C63.10-2013. 1.4.1 Measurement Uncertainty The measurement uncertainty (with a 95% confidence level) for the conducted emissions test was ±3.5 dB. The measurement uncertainty (with a 95% confidence level) for the radiated emissions test was ±5.3 dB (from 30 to 100 MHz), ±4.7 dB (from 100 to 300 MHz), ±3.9 dB (from 300 to 1000 MHz) and ±3.8 dB (from 1 GHz to 40 GHz). 1.5 Special Test Software Tests were performed manually and no special test software was used Report Ref: 19E8413-1b Page 6 of 21 2.0 Emissions Measurements 2.1 Conducted Emissions Measurements Test not performed as EUT is powered from battery. 2.2 Radiated Emissions Measurements Radiated Power measurements were made at the Compliance Engineering Ireland Ltd anechoic chamber located in Dunshaughlin, Co.
