Navigating the Menu:
- Use the MENU button to cycle through the main menu options.

- Press ENTER to confirm your selection or save changes.
Available Modes:
- DMX Mode (CH13): Allows external control of the fixture's functions (colors, movement, strobe, dimming) via a DMX controller. Set the DMX address (e.g., 'd001') and select the 13-channel mode ('CH13') using the menu.
- Automatic Mode (AU01/AU02): The fixture runs through pre-programmed light shows. 'AU01' typically refers to a quick auto mode, while 'AU02' is a slower auto mode.
- Sound Activated Mode (Sn0F): The light reacts to ambient sound or music, changing patterns and colors in sync with the beat. Adjust sound sensitivity ('S.90' to 'S.99') via the menu.
- Master-Slave Mode: Connect multiple fixtures via DMX cables. Set one fixture as the 'Master' (e.g., in Auto or Sound Activated mode) and the others as 'Slave' units. The slave units will mirror the master's operation.
