If you've recently interrupted the power supply (battery) then you will need to input the radio code. The code should be in your paperwork, if not, contact your dealer for the code. The "WAIT" code on the radio means you have input the wrong code more than 3 times and you have to wait 10 minutes before attempting to enter radio code.
