Operating Instructions
Power On/Off

Selecting Pressure Unit
Long press the 'Mode' button (often indicated by a square icon with four smaller squares) to cycle through different pressure units: PSI, BAR, KPA, and KG/CM².
Choosing Inflation Mode and Setting Pressure
The device offers four preset inflation modes:
- Car
- Motorcycle
- Bicycle
- Ball
Press the 'Mode' button (short press) to switch between these modes. Each mode has a default preset pressure, but you can adjust it using the '+' and '-' buttons.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
