Operating Instructions
Titan Switches
The ROCCAT Vulcan 121 features Titan Mechanical (Tactile) switches. These switches are designed to provide a noticeable tactile bump during actuation, offering precise feedback without excessive noise. The low-profile design of the switches and keycaps contributes to faster response times and reduced finger fatigue.

Customization with Easy-Shift[+]
ROCCAT's Easy-Shift[+] technology allows you to assign a secondary function to compatible keys. By holding down a designated modifier key, you can instantly access a second layer of commands, effectively doubling the functionality of your keyboard.
Advanced Anti-Ghosting
The keyboard features advanced anti-ghosting technology, optimized to ensure that every keystroke, especially during frantic gaming sessions, is registered accurately without conflicts.
Maintenance
Cleaning
To maintain optimal performance and appearance, regularly clean your keyboard. Use a soft, dry cloth to wipe down the surface. For deeper cleaning, you may carefully remove keycaps and use compressed air to clear debris from beneath the switches. Ensure the keyboard is disconnected from your computer before cleaning.
Durability
The Vulcan 121 is built with an aircraft-grade aluminum top plate for enhanced structural integrity and durability. The Titan switches are designed to resist dust and dirt build-up, contributing to the keyboard's longevity and consistent performance.
Troubleshooting
Common Issues
- Keyboard not responding: Ensure the USB cable is securely connected to both the keyboard and the computer. Try a different USB port.
- RGB lighting not working or stuck: Open the ROCCAT Swarm software and check the lighting settings. Try adjusting brightness or switching between different lighting profiles. Ensure the software is up to date.
- Keys not registering or double-typing: This could indicate dirt or debris under the keycap. Carefully remove the affected keycap and clean the switch area with compressed air. If the issue persists, ensure Swarm software is updated.
- Palm rest not attaching securely: Ensure both the keyboard and palm rest magnetic surfaces are clean and free of obstructions.
