Sensor Matching Procedure

To match the sensors:

Press and hold the "menu key" for 3 seconds to access the "U/S" mode.
Press the "menu key" multiple times to reach the "LID" interface, displaying IDs for all four tires.
Select the tire you want to match by pressing the "menu key" (default order: FL > FR > RR > RL).
Once a tire is chosen, the new ID will appear in the receiver after activating the sensor's ID (the internal sensor activates by charging/venting, external sensor requires reinstallation). Repeat for the remaining sensors.
After matching all sensors, press the "menu key" to save and exit.

Product Overview

This solar TPMS is an upgraded version of a standard tire pressure monitoring system, providing real-time monitoring of tire pressure and temperature while eliminating the need for frequent recharging. It addresses common issues with standard TPMS, such as occupying the cigarette lighter socket and requiring complicated setups.

The solar TPMS consists of a solar-powered display screen and four sensors. Its robust power generation allows for continuous operation, even in low-light conditions like rain or snow for over 15 days. The system features a USB charging interface, ensuring reliable performance over a long lifespan.
