Using the Arc Cube holder is easy. Just place your Arc Cubes into the slots on the panel - type holder. The Ultraman Blazar Cube can be taken out and used on its own to play 6 different sounds. To use it with the DX Arc Riser, Sword, or Galaxy, simply insert the cube into the appropriate device. Make sure to handle the cubes gently to avoid any damage. When not in use, store the cubes in the holder to keep them safe. If the sounds seem faint, check the battery status of the cube. Keep the holder and cubes away from water and extreme temperatures to maintain their functionality.
