HYQ13BBYTire Pressure Monitor System Receiver

8. Manual requirement Our product HYQ13BBY, a receiver for a Tire Pressure Monitoring System for car, will be already installed in cars (as original equipment) when placed into the U.S. market. We must hereby request that the following statements per CFR 47, Part 15 must be added to the car’s manual. This is a requirement from the Federal Communications Commission in Washington, D.C.: Per CFR 47, Part 15, Paragraph 15.21 the following statement must be added to the car’s manuals: The title "CAUTION TO USER:" or "FCC WARNING:" or "NOTE:" or relevant title, and " Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.” Per CFR 47, Part 15, Paragraph 15.19(a)(3) the following statement must be added to the car’s manual: “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.” 9. User Manual Tire Pressure Monitor System is used for monitoring and indicating about information of air pressure in vehicle’s tires. Transmitter sends to receiver the data that are information of air pressure in vehicle’s tire. The data also include temperature and battery voltage and identity code of transmitter. The receiver and the ECU judge the data. If the data of air pressure and others are not normal condition and then the receiver send signal to a warning lamp through control ECU. The warning lamp warns drivers.
