Operating Instructions

- Adjusting Speed/Direction: Use Fn + Arrow Keys (Fn + Left/Right Arrow for direction, Fn + Up/Down Arrow for speed) to modify the animation speed or direction of dynamic lighting effects.
- Adjusting Brightness: Use Fn + +/- keys (usually on the number pad) to increase or decrease the backlight brightness.

N-Key Rollover and Anti-Ghosting

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 the surface of the keyboard.
- For dust and debris between keycaps, use compressed air.
- Avoid using harsh chemicals, abrasives, or solvents as they may damage the finish or keycap legends.
- Keycap Removal (Optional): If deep cleaning is required, keycaps can be carefully removed using a keycap puller (not included). Gently pull straight up on the keycap. Reinstall by aligning the keycap with the switch stem and pressing down firmly.
- Cable Care: Avoid sharp bends or kinks in the braided USB cable to prevent internal damage.
Troubleshooting
- Keyboard Not Responding:
- Ensure the USB cable is securely plugged into both the keyboard and the computer.
- Try plugging the keyboard into a different USB port on your computer.
- Restart your computer.
- Test the keyboard on another computer to rule out a system-specific issue.
- Backlight Not Working or Incorrect:
- Ensure the backlight brightness is not set to the lowest level (use Fn + Up Arrow or Fn + + to increase brightness).
- Cycle through different backlight modes using Fn + Ins/Home/PgUp/Del/End/PgDn to see if other modes function.
- If a specific key's backlight is not working, it might indicate a hardware issue.
- Keys Not Registering or Double-Typing:
- Clean the affected key(s) with compressed air to remove any debris.
- If the issue persists, it may indicate a switch malfunction.
