GUTA Trailer Tire Pressure Monitoring System, Trailer TPMS with 10 Sensors, 6 Alert Modes, Signal Booster, Power Saving Display, Long Sensing Distance, for 3 Trailers (T1/T2/T3), for RV, for Trailer

NOTE BEFORE USAGE:1. How to get into programming mode successfully?In the process of programming the TPMS sensor, please press the CODE button of the display until a beep sound, then release, get into the Learning mode. (If release the CODE button before the beep sound, you could not into the Learning mode.)2. Why can't I see the data when the vehicle is stationary?Parking vehicle for a period of time, you may find the monitor does not display any data.1)The monitor goes into the power-saving mode. Press any button or have any vibration, and it will wake up.2)When the vehicle is stationary if you find the sensor data still cannot be read. The repeater could not boost the signal and the monitor could not receive sensors` data (Note: The power of the repeater comes from the automotive vehicle battery). Please restart the vehicle to power on the repeater.3. If there is a puncture accident?A tire pressure monitoring system could not avoid the puncture caused by sharp objects or damaged tires. Because tire pressure monitoring system can only monitor the air pressure and temperature over a period of time, but cannot monitor instantaneous changes. So it is only suitable for avoiding tire abnormalities caused by changes in air pressure or temperature, which occur slowly, not instantaneously. Friendly Remind: Do a comprehensive tire inspection for at least one month and ask your tire technician to replace your faulty tire in time.
