Instructions
Insert the USB connector from the microphone into a USB port on the front of the Xbox 360.
Turn the game console and a controller on. Insert a game disc from the "Guitar Hero" series compatible with a microphone.
Start the game and select a game mode from the main menu. The options are usually "Career" or "Quickplay."
Click the "Vocals" option when prompted for an instrument and select a song to play.
Tap the microphone to test it when the game has loaded and the band appears on stage. You will hear feedback from the tap over your television speakers if the microphone is connected properly.
