3.2 Multimedia Functions

The keyboard includes multimedia keys for convenient control of audio and other functions. Refer to the keycap legends for specific functions, often accessed via the FN key combination.

4. Maintenance

4.1 Cleaning

  • Keycaps: The ABS keycaps are designed to be abrasion-resistant and non-greasy. For general cleaning, use a soft, damp cloth. For deeper cleaning, keycaps can be removed (using a keycap puller) and washed with mild soap and water, then thoroughly dried before reattaching.
  • Keyboard Body: Wipe the keyboard body with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
  • Switches: If dust or debris accumulates under the keycaps, use compressed air to clean the switches.

4.2 Switch Maintenance

As the switches are hot-swappable, they can be easily replaced if they become faulty or if you wish to change your typing feel. Refer to section 2.2 for switch replacement instructions.

5. Troubleshooting

  • Keyboard not responding:
    Ensure the keyboard is charged if using wireless modes. Check the connection mode switch (2.4G, Bluetooth, Wired) is in the correct position. For wired mode, ensure the Type-C cable is securely connected to both the keyboard and the computer. For 2.4G, ensure the USB receiver is properly inserted.
  • Bluetooth connection issues:
    Make sure the keyboard is in Bluetooth pairing mode (indicator flashing white). On your device, try forgetting the keyboard and re-pairing it. Ensure your device's Bluetooth is enabled and within range (up to 10m).
  • 2.4G Wireless connection issues:
    Ensure the USB receiver is plugged into a working USB port. Try plugging the receiver into a different USB port. Ensure the keyboard is switched to 2.4G mode.
  • RGB lights not working or stuck:
    Try cycling through the light effects using FN+ | or changing colors with FN+Enter. If issues persist, perform a factory reset for the lighting by pressing and holding FN+ESC for 3 seconds.
  • Keys not registering or ghosting:
    The K98 features full anti-ghosting (no impact for all keys), so this should be rare. Ensure the switches are properly seated. If a specific key is faulty, consider replacing the switch (refer to section 2.2).
  • Unexpected behavior:
    Try resetting the keyboard to factory settings by pressing and holding FN+ESC for 3 seconds.
