Maintenance

Cleaning

To maintain your keyboard's performance and appearance:

  • Disconnect the keyboard from power before cleaning.
  • Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe the keycaps and chassis.
  • For dust and debris between keys, use compressed air or a small brush.
  • Avoid harsh chemicals or abrasive materials that could damage the finish or keycap legends.

Troubleshooting

Connectivity Issues

  • Bluetooth Disconnection: Ensure the keyboard is charged. Re-pair the device if connection is lost. Some operating systems may require manual reconnection after waking from sleep.
  • Wired Connection Not Detected: Check the USB-C cable connection at both ends. Try a different USB port or cable.

Key Input Problems

  • Keys Not Responding: Ensure the correct operating system mode is selected. If using hot-swappable switches, ensure switches are fully seated.
  • Incorrect Key Output: Verify the keyboard layout in your operating system settings. If using VIA, check your custom keymaps for unintended reassignments.

Backlight Issues

  • Backlight Not Working: Ensure the backlight is enabled and brightness is adjusted. Check keyboard battery level if in wireless mode.
  • Dim LEDs: The brightness of the LEDs can vary. Ensure maximum brightness is set.

Physical Switches (Bluetooth/Cable, Win/Mac)

  • Difficulty Reading Labels: The labels on the small physical switches for connectivity and OS selection can be very small. Use adequate lighting or a magnifier if needed to ensure correct selection.
