3. Setup Guide

3.1 Installing Switches and Keycaps

The GMK98 is a barebones kit, meaning switches and keycaps are not pre-installed. The PCB supports 3-pin and 5-pin hot-swappable mechanical switches, allowing for easy installation without soldering.

1. Switch Installation: Align the pins of your desired mechanical switch with the holes on the PCB. Gently press the switch until it clicks into place. Ensure the pins are straight to avoid bending.
2. Keycap Installation: Place the keycaps onto the installed switches, ensuring they are firmly seated. Use the provided keycap puller for easy removal if needed.

5. Maintenance

5.1 Cleaning the Keyboard

• Disconnect the keyboard from all power sources before cleaning.
• Use a soft, dry cloth to wipe the surface of the keyboard.
• For deeper cleaning, remove keycaps using the provided keycap puller and use compressed air to clear debris from between switches.
• Avoid using harsh chemicals or abrasive materials that could damage the keyboard's finish or components.

5.2 Replacing Switches and Keycaps

Thanks to the hot-swappable PCB, switches and keycaps can be easily replaced without soldering.

• Use a switch puller (not included, but often comes with switches) to carefully remove switches.
• Use the provided keycap puller to remove keycaps.
• Install new switches and keycaps as described in Section 3.1.

6. Troubleshooting

6.1 Keyboard Not Responding

• Wired Mode: Ensure the USB Type-C cable is securely connected to both the keyboard and the computer. Try a different USB port or cable.
• 2.4GHz Wireless Mode: Verify the 2.4G receiver is properly inserted and the keyboard is set to 2.4GHz mode (FN+R). Try re-pairing by pressing FN+R.
• Bluetooth Mode: Check if the keyboard is paired correctly (FN+Q/W/E). Ensure Bluetooth is enabled on your device. Try re-pairing the keyboard.
• Battery: Ensure the keyboard has sufficient charge. Connect it to a power source.

6.2 RGB Backlight Not Working

• Press FN + | to cycle through lighting effects.
• Check VIA software settings to ensure RGB is enabled and configured correctly.
