4. Operating Instructions
Basic Operation:
The 18 buttons on the controller are pre-configured for standard fighting game layouts. Refer to your game's control settings for specific button assignments.
Tournament Lock Switch:
To prevent accidental presses of non-essential buttons during competitive play, utilize the tournament lock switch. Locate the switch on the top right side of the controller. Flipping this switch will disable certain buttons, typically those used for system functions or macros, ensuring only gameplay-critical inputs are active.

RGB Illumination:
The controller features multiple RGB illumination modes. Specific button combinations or software (if available) can be used to cycle through the 8 different lighting effects and adjust brightness. Refer to the official FILCO website for detailed instructions on illumination control.
SOCD Cleaning Mode:
The built-in SOCD (Simultaneous Opposite Cardinal Directions) cleaning ensures that conflicting directional inputs (e.g., Left + Right) are resolved according to tournament standards. This prevents unfair advantages and maintains competitive integrity. The controller automatically handles SOCD cleaning.
5. Maintenance
Cleaning:
- Wipe the controller surface with a soft, dry cloth.
- For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Ensure no liquid enters the button gaps or USB port.
- Do not use harsh chemicals, solvents, or abrasive materials, as these can damage the surface.
