Maintenance
Cleaning the Keyboard
- Disconnect the keyboard from your computer before cleaning.
- Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe down the keycaps and chassis.
- For deeper cleaning, use a can of compressed air to remove dust and debris from between the keycaps.
- Avoid using harsh chemicals or abrasive materials that could damage the keyboard's finish.
Hot-Swappable Switches and Keycaps
The AK820 features a hot-swappable design, allowing you to easily replace switches and keycaps without soldering. This enhances the keyboard's maintainability and customization options.
- Removing Keycaps: Use the provided keycap puller to gently lift keycaps off the switches. Pull straight up to avoid damaging the switch stem.
- Removing Switches: Use the provided switch puller to grasp the clips on the top and bottom of the switch. Apply gentle pressure and pull the switch straight up from the PCB.
- Installing Switches: Align the pins of the new 3-pin or 5-pin switch with the holes on the PCB. Press down firmly until the switch clicks into place. Ensure pins are not bent.
- Installing Keycaps: Align the keycap with the switch stem and press down firmly until it is seated securely.
