5. Maintenance
To ensure the longevity and optimal performance of your KCEVE USB 3.0 Switch, please observe the following maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the device. Avoid using liquid cleaners or aerosols, which may damage the unit.

6. Troubleshooting
If you encounter issues with your KCEVE USB 3.0 Switch, please refer to the following common troubleshooting tips:
- No Device Recognition / Unstable Connection:
- Ensure all USB cables are securely connected to both the switch and the computers/devices.
- For high-power USB devices (e.g., external hard drives), connect a 5V/2A power adapter (not included) to the DC 5V port on the switch. This is crucial for stable operation.
- Try using different USB cables to rule out faulty cables.
- Wireless Mouse/Keyboard Interference:
- If experiencing interference with a wireless mouse or keyboard, connect its dongle to an extension cable to move it further away from the switch or other potential sources of interference.
- The remote control function can be disabled if RF interference is a persistent issue.
- Incorrect Switching Order:
- Some units may have a non-sequential switching order (e.g., pressing button 1 switches to PC 4, and button 4 switches to PC 1). If this occurs, note the actual switching behavior and label the buttons accordingly for convenience.
- LED Indicator Brightness:
- The LED indicators are designed to be bright for clear visibility. If the brightness is too intense for your environment, consider adjusting the placement of the switch or using a small piece of tape to dim the LEDs.
- Short Included Cables:
- The included USB cables are approximately 0.8 meters long. If your setup requires longer cables, please purchase additional USB 3.0 extension cables or longer A-to-B cables as needed.
