Operation has been confirmed with new batteries. You can switch modes by sliding the buttons on the left side (1, 2, and 3). Batteries are not included. Mode 1: Pressing the left button on the top of the main unit will deploy and pop up the cover parts. Touching the outside of the circle activates light and sound, then touching the center allows you to select an alien. Pressing it in then activates the transformation sound. There are 8 types of aliens to choose from, and the alien's name changes depending on where you touch. You can also make the transformation sound even without selecting an alien by pressing it in. After pressing it in, you can close the cover parts. Mode 2: Touching the touch sensor plays 8 different sound effects. Pressing it in doesn't change the sound. Mode 3: Touching the touch sensor plays 1 sound effect. After playing it 6 times, the transformation解除 sound will play. Ben 10 Omniverse Omnitrix Omnitrix Touch Cartoon Network
