Instructions
Remove the microphone from the plastic bag inside the "Rock Band" box, and unravel the cord.
Plug the cord into one of the Wii's open USB ports. Press the "Power" button to turn the Wii on, or insert the "Rock Band" game into the console to turn the Wii on automatically.
Press any button on a Wii remote to turn it on and sync it to the console. With the "Rock Band" game running, you may use the remote to scroll through menus and sign the microphone in so the game detects it. The remote also changes microphone settings, such as volume.
