5. Troubleshooting and Alarms
The system provides real-time warnings for various tire anomalies:
5.1 Leak Alarm
When a tire's air pressure drops below the lower limit within one launch cycle, the buzzer will sound. The corresponding tire icon, pressure data, TPMS icon, and air leak icon will flash continuously. Press the Right button to stop the buzzer alarm. The alarm clears once the gas leak is resolved.
5.2 Low-Voltage Alarm
If any tire pressure is detected to be lower than 75% of the standard tire pressure, the buzzer will sound. The corresponding tire icon, pressure data, TPMS icon, and low-pressure icon will flash continuously. The alarm clears when the tire pressure is equal to or higher than the alarm threshold.
5.3 High Voltage Alarm
If a tire's pressure exceeds 125% of the cold tire standard when the vehicle is fully loaded, the buzzer will sound. The corresponding tire icon, pressure data, TPMS icon, and high-pressure icon will flash continuously. The alarm clears when the tire pressure drops below the alarm threshold by 0.1 Bar.
5.4 Sensor Low Battery Alarm
When the battery power of any sensor transmitter falls below 2.4V, the buzzer will sound. The corresponding tire pressure icon and low battery icon will flash continuously. This alarm will only sound once after each restart and will automatically clear after 30 seconds.
6. Maintenance
6.1 External Sensor Battery Exchange Method
When replacing the battery of an external sensor, ensure you disassemble and reassemble one by one. Do not mix or disassemble multiple sensors at the same time. The battery type required is CR1632 (working temperature -30°C to 80°C).
- Before disassembling, prepare a nut wrench. Turn the nut clockwise to separate the nut and the sensor, then remove the sensor counterclockwise.
- Use a wrench to unscrew the upper cover of the sensor in a counterclockwise direction.
- Carefully remove the old battery from the battery holder and dispose of it according to environmental protection guidelines.
- Note the positive and negative positions (positive "+" facing upwards) and install a new CR1632 lithium battery.
- Screw on the upper cover of the sensor, and then use a wrench to tighten it clockwise.
6.2 Restore Factory Settings
To restore the monitor to its factory default settings:
- In standby mode, long press the "Set key" for 3 seconds to enter the system setting state.
- Press the Left button once; the '5' icon appears in the upper left corner.
- Press the "Set key" twice. The machine will restart and restore all parameters to factory defaults.
6.3 Sensor Replacement
If you need to replace a sensor, first replace the new sensor, then restore the factory settings. The machine will automatically update the sensor. If an individual sensor does not update, reinstall it at the corresponding position. If you change the sensor first and then restore factory settings, you may need to drive for 10-30 minutes for the system to automatically update the sensor.
7. User Tips
- Always ensure the monitor is fully charged before long trips to benefit from continuous solar charging.
- Regularly check sensor battery levels, especially for external sensors, to ensure uninterrupted monitoring.
- Familiarize yourself with the alarm sounds and flashing icons to quickly identify and address tire issues.
- For optimal performance, ensure sensors are installed correctly and securely to prevent false readings or damage.
8. Warranty and Support
The product warranty is valid only if the system is installed correctly by qualified operators according to the installation manual. Damage to sensors due to improper installation or disassembly will void the product warranty.
