1. Constitution of the Tire Pressure Monitoring System for vehicle FCC ID:OUCG8D-365M Tire Pressure Monitoring System is the system that receives the information, from transmitters installed at each tire, about the inflation pressure or temperature of tires detected by the sensor, so that the system can detect the abnormality of tires like fallen inflation pressure. This system consists of transmitter, receiving antenna, and receiver. The transmitter sends information of tire, read by the sensor, in the form of radio wave at constant intervals. The receiver is fixed inside the vehicle. If IG is OFF, it works intermittently to prevent the battery exhaustion. When the receiver detects the synchronous code and IG is ON, it runs continuously to receive the signals completely. If the received code is normal, the system will not inform the user. As shown below, in the case that the transmitter sends information that the tire is in abnormal condition, and that the receiver system has a trouble, the system will inform the user with lighting up Warning bulb. TPMS Warning bulb is lit by the following situations. Bulb disconnection detection outputThe warning light is On for 3 sec. when IG=OFFON Tire air pressure warning output (Warning light is ON) System warning output (Warning light is blinking) Tire Antenna Transmitter 1 Pressure sensor 1 CPU Transmission circuit Transmitter 2 Transmitter 3 Transmitter 4 Transmitter SP Receiver EEPROM CPU R e c e i v i n g c i r c u i t Bulb Figure 2-1 System Architecture

2. Users manual (provisionally) FCC ID:OUCG8D-365M Tire inflation pressure warning light This light illuminates if the inflation pressure of any tire (except for compact spare tire) drops while the ignition key is in the ON position. It normally illuminates when the ignition key is turned to the ON position and goes off a few seconds later. Warning light If the warning light illuminates while driving Avoiding hard braking, hard steering, and high speeds, drive to the nearest gas station or authorize car dealer and adjust the tire inflation pressures.(except for compact spare tire) If the warning light blinking while driving It is thought abnormality of the device, go to the check to the nearest car dealer as soon as possible. Whenever the tires and wheels are replaced with new ones Tire inflation pressure sensors must be fitted on the new wheels and their ID codes must be programmed into the system. Have tire and wheel replacement performed by an authorized car dealer to avoid the risk of damaging the tire inflation pressure sensors. If the tire inflation pressure warning-light does not illuminate when the ignition key is turned to the ON position the system may be faulty. If the tire inflation pressure warning light illuminates while you are driving, avoid hard braking, hard steering, and high speeds. Otherwise, you could make the vehicle unstable and have a serious accident. The tire inflation pressure warning light may not illuminate immediately in the event of a tire blowout or rapid leak..

FCC ID:OUCG8D-365M 5. Features Battery saving The receiver works intermittently to reduce the battery consumption. The microcomupter embedded on the receiver controlls the power supply for the RF circuit. In case of the microcomputer detects the wake-up signal during the power supplied, the microcomputer continue supplying the power until the data frame will be received.
