Things You'll Need
Instructions
Remove the batteries from the wireless microphone and replace them with new ones if needed.
Launch your Xbox 360 and start your "Rock Band" game.
Press the "Power/Connect" on the microphone and allow it to connect to your Xbox system. You should see indicator lights on your microphone that correspond to a green indicator light on the ring around your Xbox's power button when it is properly connected.
Wait for the system to automatically detect and download an upgrade that will fix compatibility issues with the Xbox wireless microphone when playing "Rock Band 2."
Stand within 10 meters of the Xbox console while playing the "Rock Band" game. If you are out of range, the microphone will not work properly. The lights on the microphone will flash until you move back into wireless range of the Xbox system.
