I Need Instructions On How To Operate A Tamagotchi?

The standard Tamagotchi has three buttons. The first button (button a) allows you to select/scroll which action you' d like to use. When you keep pressing this it scrolls though all the functions around the top and bottom of the screen.
At the top there is status, feed, toilet, games and friends. At the bottom there is discipline, medicine, lights, notebook and attention.
The second button in (button b) is the choose/set button. The third button (button c) is the cancel button.

You now need to make sure your little character gets food, playtime and of course plenty of attention. Here's a good visual guide to setting up and using your Tamagotchi: www.mimitchi.com
