1：Parking mode a: The sensor measures pressure ,temperature and voltage every 4 seconds. b: The sensor transmits pressure and temperature every 5 minutes if the tire's pressure is normal. It transmits one time. c: The sensor transmits pressure and temperature as soon as the tire's pressure is abnormal. It transmits six times continue. d: Once the car's speed reaches over 15km/h,the sensor transmits signal at once. 2：moving mode a: The sensor measures pressure ,temperature and voltage every 4 seconds. b: The sensor transmits pressure and temperature every 4 minutes if the tire's pressure is normal. It transmits one time. c: The sensor transmits pressure and temperature as soon as the tire's pressure is abnormal. It transmits six times continue. 3：Wake up The sensor can be waked up by handheld. The sensor will transmit signal when it was waked up. 4: Technical Characteristics Car Sensor Technical Parameters Description NO.
