Maintenance
Cleaning the Keyboard
- Disconnect the keyboard from your computer before cleaning.
- Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe down the keycaps and aluminum top plate.
- Avoid using harsh chemicals, abrasive cleaners, or excessive moisture, as these can damage the keyboard.
- For cleaning between keycaps, use compressed air to remove dust and debris.
Switch Care
The ROCCAT Titan switches are designed to resist dust build-up. Regular cleaning as described above will help maintain their performance and longevity. Avoid disassembling the switches unless you are an experienced technician, as this can void your warranty.

Troubleshooting
Keyboard Not Responding
- Ensure the USB cable is securely connected to both the keyboard and the computer.
- Try plugging the keyboard into a different USB port.

Lighting Issues or Software Malfunctions
- Ensure ROCCAT Swarm software is installed and up to date.
- Check for firmware updates for the keyboard within the Swarm software.
- If the keyboard is not recognized by Swarm or exhibits erratic behavior, navigate to your computer's Device Manager (Windows) or System Information (macOS). Look for duplicate or error-reporting keyboard drivers. Uninstall any problematic drivers and restart your computer. Reinstall Swarm if necessary.
- Avoid connecting the keyboard through KVM switches if experiencing software or firmware update issues, as this can sometimes interfere with proper communication.
