5.3 Magnetic Switch Features
The magnetic switches offer advanced control and precision:
- 0 Dead Zone: Achieve zero dead zones on both upper and lower levels for quick and uninterrupted responses.
- Adjustable Trigger Points: The magnetic switches allow for precise adjustment of the key trigger and reset points (RT adjustment accuracy up to 0.01mm). This enables features like emergency stop, rapid walk, and continuous drum beat in games.
- High Polling Rate: The 8000Hz polling rate ensures up to 8 times faster operation information transmission compared to traditional 1KHz keyboards, providing quicker in-game response times.


6. Maintenance
- Cleaning Keycaps: The PBT keycaps are durable and resistant to shine. Use a soft, damp cloth to wipe them clean. For deeper cleaning, keycaps can be carefully removed (using a keycap puller, not included) and washed with mild soap and water, ensuring they are completely dry before reattaching.
- Cleaning the Keyboard Body: Use a soft, dry cloth to wipe the keyboard body. For dust and debris between keys, use compressed air.
- Switch Maintenance: The magnetic switches are designed for longevity. Avoid spilling liquids directly onto the switches. If a switch feels inconsistent, ensure no debris is lodged within.
- Cable Care: Avoid sharp bends or excessive pulling on the USB cable to prevent damage.

7. Troubleshooting
- Keyboard Not Responding:
- Ensure the USB cable is securely connected to both the keyboard and the computer.
- Try connecting the keyboard to a different USB port on your computer.
- Test the keyboard on another computer to rule out system-specific issues.
- RGB Backlight Not Working/Incorrect:
- Check if the backlight is turned off or set to minimum brightness using the keyboard's function keys.
- Access the web driver to ensure lighting settings are correctly configured.
- Keys Registering Incorrectly or Not at All:
- Clean around the affected key to remove any debris.
- If using the 0 dead zone feature, ensure the dead zone is manually set to approximately 0.1mm to prevent accidental triggers from minor environmental factors (e.g., hand movements, airflow, table shaking). This adjustment can be made via the web driver.
- Since switches are hot-swappable, consider carefully removing and re-seating the affected switch.
- Web Driver Not Accessible:
- Ensure your computer has an active internet connection.
- Verify the web driver URL is entered correctly.
- Try a different web browser.
8. User Tips
- Optimize Magnetic Switch Settings: Experiment with the adjustable trigger points and dead zone settings via the web driver to find the perfect balance for your gaming style. A recommended manual dead zone setting is around 0.1mm to avoid unintended key presses.
- Leverage Programmable Keys: Use the web driver to program custom macros or reassign keys for specific games or applications, enhancing your workflow and gaming performance.
- Explore RGB Effects: Take advantage of the 16 million color RGB backlighting to personalize your keyboard's appearance. Create unique lighting profiles for different games or moods.
- Stable Placement: The keyboard features a thick shell design for stability. Ensure it is placed on a flat, stable surface to prevent movement during intense gaming sessions.
