Gasket Structure

The keyboard is built with a soft gasket-mounted structure, combining a 1.2mm FR4 fiberglass dual-layer PCB with individual switch slots. This design, along with PORON foam, IXPE pad, PET sheet, DEPDM, and molded silicone, provides a deeper sound, softer touch, and enhanced typing feedback.

Maintenance

Cleaning

To clean your keyboard, power it off and disconnect it from your device. Use a soft, dry cloth to wipe the surface. For deeper cleaning, use the provided key puller to remove keycaps and clean underneath with compressed air or a small brush. Avoid using harsh chemicals or abrasive materials.

Switch and Keycap Replacement

Thanks to the hot-swappable design, you can easily replace switches and keycaps. Use the included 2-in-1 key puller to carefully remove keycaps and switches. Ensure replacement switches are compatible (3-pin or 5-pin mechanical switches) and insert them gently until they click into place.

Troubleshooting

• Keyboard not responding: Ensure the keyboard is charged and the correct connectivity mode (2.4G, BT, or USB) is selected via the switch on the back. For wireless modes, check if the receiver is properly inserted or if Bluetooth is paired.
• RGB lighting not working: Check lighting settings via the control knob or web driver. Ensure the keyboard is not in a low-power state.
• Keys not registering: If specific keys are not working, try replacing the switch using the hot-swappable feature. Ensure the switch is fully seated.
• Connectivity issues: For 2.4G, try moving the receiver closer to the keyboard. For Bluetooth, ensure your device's Bluetooth is enabled and the keyboard is paired. Try re-pairing if issues persist.
