Troubleshooting
| Problem | Solution |
|---|---|
| Keyboard not responding. | Ensure the keyboard is powered on. Check battery levels and replace if necessary. Verify the correct connection mode (2.4Ghz or Bluetooth) is selected. For 2.4Ghz, ensure the USB receiver is properly plugged in. For Bluetooth, ensure it's paired and within range. |
| Lag or intermittent connection. | Move the keyboard closer to the receiver/device. Avoid interference from other wireless devices. Re-pair the Bluetooth connection or re-plug the 2.4Ghz receiver. |
| Keys not registering or double-typing. | This could indicate a faulty switch. Use the switch puller to replace the affected switch with one of the extra switches provided. Ensure the switch is fully seated. |
