All you have to do to take your UVee out of the sleep mode is to open and close the lid one time, then a second time will start the sanitizing process once the lid is closed.  If it has been awhile since you have used your UVee you may have to open it a few times, the logo on the front will light up signaling that the cleaning system is in process. When the light goes off, the cycle is complete.  If you open UVee while the cleaning system is operating the lights will shut off.  You will have to reopen the lid twice again to start it up.  Your UVee system was designed to clean only when you need it to.  That way the bulbs are preserved for longer use.
