http://www.tpmseuroshop.com/documents/declaration_conformities Schrader Electronics Ltd Unit 11 Technology Park Belfast Road Antrim, Northern Ireland, BT41 1QS TPMS (Tire Pressure Monitoring Sensor) Model PF4 User Manual Schrader Sensor Overview The Schrader Electronics TPMS (Tire Pressure Monitoring) Sensor is designed to be used in a direct measurement TPM System. 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 http://www.tpmseuroshop.com/documents/declaration_conformities Schrader Electronics Ltd Unit 11 Technology Park Belfast Road Antrim, Northern Ireland, BT41 1QS FCC ID: MRXFP4 IC: 2546A-FP4 This device complies with Part 15 of the FCC Rules Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation.
