5. Maintenance
5.1 Cleaning the Keyboard
To clean the keyboard, disconnect it from all power sources. Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution. Avoid spraying liquids directly onto the keyboard. For cleaning between keycaps, use compressed air or a small brush.
5.2 Replacing Keycaps and Switches
Use the provided keycap puller to gently remove keycaps. For switches, use the switch puller to carefully grip and extract the switch from its socket. When inserting new switches, align the pins correctly with the socket holes to prevent damage. Ensure the keyboard is disconnected before performing any replacements.
6. Troubleshooting
- Keyboard not responding:
- Ensure the keyboard is charged.
- Check the connection mode (wired, 2.4GHz, Bluetooth) and ensure it matches your device.
- For 2.4GHz, ensure the USB receiver is properly inserted.
