6. Troubleshooting

If you encounter issues with your A4 Tech 3100N, refer to the following common solutions:

• No Connection / Device Not Responding:
  • Ensure the USB receiver is securely plugged into a working USB port. Try a different USB port.
  • Check the batteries in both the keyboard and mouse. Replace them if necessary.
  • Remove and re-insert the USB receiver. Sometimes, a simple reset of the connection can resolve the issue.
  • Move the keyboard and mouse closer to the USB receiver.
• Lagging or Intermittent Connection:
  • Reduce the distance between the devices and the USB receiver.
  • Ensure there are no large metal objects or other wireless devices (e.g., Wi-Fi routers, cordless phones) operating nearby that could cause interference.
  • If using a USB extension cable, ensure it is not excessively long or of poor quality.
• Keyboard Typing on its Own / Erratic Input:
  • This can sometimes be caused by wireless interference. Try the steps for lagging connection.
  • Remove the batteries from the keyboard for a few minutes, then re-insert them to reset the device.
• Mouse Not Tracking Properly:
  • Ensure the mouse sensor on the underside is clean and free of debris.
  • Try using the mouse on a different surface. The V-track engine is versatile, but extreme surfaces (e.g., glass, highly reflective) may still pose challenges.
