4.2 Sensor Installation
The external sensors are labeled for specific tire positions: FL (Front Left), FR (Front Right), RL (Rear Left), RR (Rear Right). Ensure correct placement for accurate readings.
- Screw on the anti-theft nut onto the tire valve stem.
- Screw the corresponding sensor onto the valve stem until it is hand-tight.
- Use the provided wrench to tighten the anti-theft nut against the sensor to secure it.
- Repeat for all four tires.
After installation, drive for a few minutes for the sensors to transmit data to the monitor.
5. Operating Instructions
5.1 Display Overview
The monitor displays real-time pressure and temperature for each tire, along with battery status and charging indicators.

5.2 Unit Switching (PSI/Bar, C/F)
Refer to the monitor's buttons (usually labeled "Select" or "Menu") to switch between pressure units (PSI/Bar) and temperature units (Celsius/Fahrenheit). Consult the quick start guide included in the package for specific button functions.
5.3 Alarm Functions
The system provides visual and audible alerts for various tire conditions:
- Fast Air Leakage Alarm: Alerts when a rapid drop in pressure is detected.
- Slow Air Leakage Alarm: Alerts for gradual pressure loss.
- High Pressure Alarm: Alerts if tire pressure exceeds the preset maximum.
- High Temperature Alarm: Alerts if tire temperature exceeds the preset maximum.
- Sensor Failure Alarm: Indicates a sensor is not transmitting data.
- Sensor Low Battery Alarm: Indicates a sensor battery needs replacement.
When an alarm occurs, identify the affected tire on the display and take appropriate action.
6. Maintenance
6.1 Monitor Charging
The monitor can be charged via its built-in solar panel or through the USB charging port.
- Solar Charging: Place the monitor in direct sunlight for optimal charging.
- USB Charging: Connect the monitor to a 5V USB power source using the provided USB cable. This is recommended during cloudy weather or for initial charging.

6.2 Sensor Battery Replacement
When a sensor low battery alarm is triggered, replace the battery (CR1632) as follows:
- Remove the sensor from the tire valve stem.
- Use the provided wrench to carefully open the sensor's battery cover.
- Remove the old CR1632 battery.
- Insert a new CR1632 battery, ensuring correct polarity.
- Close the battery cover and re-install the sensor on the tire valve stem, securing it with the anti-theft nut.
Note: An illustrative image for sensor battery replacement is not available in the provided media. Please follow the text instructions carefully.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Monitor not turning on | Low battery; Power button not pressed. | Charge the monitor via USB or solar. Press and hold the power button. |
| No tire data displayed | Sensors not installed correctly; Sensor battery low/dead; Vehicle not moving. | Check sensor installation. Replace sensor battery. Drive for a few minutes to activate sensors. |
| Inaccurate readings | Sensor not fully tightened; Incorrect sensor placement. | Ensure sensors are tightly secured. Verify sensors are on the correct tire positions (FL, FR, RL, RR). |
| Alarm sounds frequently | Tire pressure/temperature outside safe range; Alarm thresholds set too narrow. | Check tire pressure/temperature and inflate/deflate as needed. Adjust alarm thresholds if necessary (refer to quick start guide). |
