1. Important statement 1.1 Welcome to use Carxpert tire pressure monitoring system. The installation proposal of this product is operated by professionals and equipment. Please read this manual carefully before installing this product to ensure correct installation and use. 1.2 This product is suitable for radial tires and aluminum alloy rim with a standard pressure of ≤3.0 bar, not for steel rim.
1.8 Specifications and technical parameters may be changed due to upgrades and other reasons, resulting in inconsistence with the instruction manual. Please prevail in kind and manufacturers reserve the right to explain. 2. Working principle The tire pressure monitoring system, referred to as TPMS, works by monitoring the internal pressure and temperature of the tire through a sensor mounted on the tire, and transmitting the collected data information to the display installed in the cab by using radio frequency technology.
4. Installation instruction 4.1 Display installation Long press the "-" key for 3 seconds to turn on/off, use anti-slip mat to securely place on the dashboard for easy observation and sunlight. The monitor is turned on in advance. The tire data will be displayed in turn when the sensor is installed.

4.2 Sensor installation(take D sensor as a sample) Each sensor is labeled with a corresponding position, such as left front wheel A, right front wheel B, right rear wheel C, and left rear wheel D, which must be accurately installed on the corresponding hub. After installation, attach a warning label near the rim of the sensor.

The installation angle of the sensor electronic module must be parallel to the rim, which is more conducive to ensuring continuous work and accuracy.
b. After the sensor installation is complete, check the tires for air leaks and spray the valve nozzle with foam water to confirm. If the air leaks, please adjust the valve angle or clean the rim hole. Tips: If there is no data displayed after installation, please inflate or deflate the corresponding tire or drive a certain distance at a speed of more than 30 kilometers per hour for normal display.

Tips: After the display goes to sleep or is turned off, the solar panel will continue to work. When the temperature inside the car exceeds 55 °C, the display will automatically stop charging to protect the battery and safety. 5.3 Display backlight mode The light adjustment can be automatic or manual, subject to actual product model.

Icon & Description Abnormal High temper- ature alarm When the monitor detects a tire temperature exceeding the alarm value, the tire temperature alarm is triggered. The alarm icon“ ” flashes at the same time and emits alarm sound “di…di…di…”. The picture shows high temperature alarm for the left front wheel.
6. Parameter settings Please follow the tire pressure value in the vehicle manual to inflate the tire. High pressure alarm value = tire pressure value X 125%; low pressure alarm value = tire pressure value X 75%; High temperature alarm value=80℃.

3. Why the tire data of a certain monitor is not updated for a long time? Possible causes: (1) Electromagnetic interference exists in the location or environment. For example, some recorders and navigators have electromagnetic interference. Please change the location (far away from the interference source) to solve the problem.

8.Where can I find the standard inflation pressure of a tire? Answer: Generally you can find it in the doorpost, fuel tank cover, glove box, and vehicle manual. 9.Is the tire imbalance large after installing the sensor? Answer: The sensor uses a miniature module, and the weight (including the valve) is only about 22 grams.
