6. Maintenance
6.1. Cleaning the Keyboard
To clean your keyboard, first disconnect it from your computer. Use a soft, lint-free cloth to wipe down the keycaps and chassis. For deeper cleaning, you can remove the keycaps using the provided keycap puller and clean underneath with compressed air or a small brush. Ensure the keyboard is completely dry before reconnecting.

The SK61's hot-swappable design allows for easy replacement of keycaps and switches. Use the provided keycap puller to gently remove keycaps. To remove switches, use the switch puller tool, carefully gripping the switch and pulling upwards. When inserting new switches, align the pins correctly with the sockets to avoid bending them.
6.3. Water Resistance
The keyboard features a water-resistant mainboard (IPX6 rated). While it can withstand splashes and spills, it is not fully waterproof and should not be submerged. In case of a spill, disconnect the keyboard immediately, dry it thoroughly, and allow it to air dry completely before reconnecting.
7. Troubleshooting
- Keyboard not responding: Ensure the USB-C cable is securely connected to both the keyboard and the computer. Try a different USB port or cable.
- Backlight issues: Use FN key combinations (FN + \|, FN + [, FN + ], FN + ;, FN + ') to adjust or cycle through backlight modes and brightness. If issues persist, check the driver software.
- Keys not registering: Verify that the switches are properly seated. If a specific key is not working, try replacing its switch with a spare one (if available) or a switch from a less-used key.
- Software not detecting keyboard: Ensure the keyboard is connected via USB-C. Reinstall the driver software from the EPOMAKER website.
