Troubleshooting

Common Issues and Solutions:

• Keyboard not connecting:
  • Ensure the keyboard is powered on.
  • For 2.4GHz connection, verify the USB receiver is securely plugged into a working USB port and the 2.4G key is pressed.
  • For Bluetooth connection, ensure Bluetooth is enabled on your device, the keyboard is in pairing mode (flashing BT1/BT2 light), and you have selected the correct device to pair. Try unpairing and re-pairing if issues persist.
  • Check battery levels and replace if necessary.
• Keys not responding or delayed input:
  • Ensure the keyboard is within the effective operating range (up to 10 meters).
  • Check for interference from other wireless devices.
  • Replace batteries if the low battery indicator is flashing.
  • If using Bluetooth, try switching to the 2.4G connection if available, or vice versa, to rule out connection type issues.
• Low battery indication:
