THINGS TO TRY

   1. Turn off the console, and then remove the MU.
   2. Turn on the console again to determine whether you still receive the error message.
   3. If you do not receive the error message, turn off the console, and then reinsert the MU. Turn on the console again.
   Note You may have to try this procedure more than one time to verify that you only receive the error message when you insert the MU.
4. Disconnect and then reconnect the power supply and the cables from the console. To do this, follow these steps:
   1. Turn off the console.
   2. Disconnect the cord that connects the power supply to the back of the console.
