Using your Tamagotchi is easy. First, make sure the CR2032 battery is installed. You'll see your Tamagotchi on the screen. To take care of it, use the buttons to feed it when it's hungry and clean up after it when it makes a mess. If it starts to act up and bother you when it doesn't need anything, you can discipline it. Don't forget to play the Character game with it. Your actions in taking care of your Tamagotchi and how well you do in the game will determine what kind of Adult Tamagotchi you'll get. Keep it attached to your bag so you can always have it with you. Just be careful not to drop it or expose it to water. When the battery runs out, replace it with a new CR2032 battery.
