Check the battery for 3.6V If it is low, replace with a Lithium 3.6V AA. You will need very good soldering skills or have a reputable tech replace it so the connections don't become damaged on the board. Then do a clear. You can purchase the leave in clear chips , which are installed and never removed again , or the removeable clear chips that are inserted and then removed after the clear is completed and then reinstall the original chips. You can also mount a 2 AA battery holder with standard 1.5V Alkaline on the front outside of the metal tray with mounting tape and then change the batteries anually with the machine ON, and not have to deal with the clear procedures caused by dead batteries.
