4. Maintenance
4.1 Cleaning the Keyboard
Regular cleaning helps maintain the keyboard's performance and appearance.
- Disconnect the keyboard from your computer before cleaning.
- Use a can of compressed air to remove dust and debris from between the keycaps.
- Wipe the keycaps and keyboard surface with a soft, slightly damp cloth. Avoid excessive moisture.
- For stubborn grime, a small amount of isopropyl alcohol on a cloth can be used, but avoid direct application to switches.
4.2 Keycap and Switch Replacement
The keyboard features replaceable switches, allowing for customization or repair. Keycaps can also be removed for cleaning or aesthetic changes.
- Use the provided keycap puller (if included) to gently remove keycaps. Hook the puller onto two opposite sides of the keycap and pull straight up.
- To replace a switch, first remove the keycap. Then, use a switch puller (not included, typically) to carefully unclip and pull the switch straight out.
- When inserting a new switch, align the pins with the holes on the PCB and press down firmly until it clicks into place. Ensure the switch is compatible with the keyboard's hot-swappable sockets.
- Press the keycap back onto the switch stem until it is secure.
