Question My 2290 displays ERROR CODE 13 when I power up. I also have lost all my presets. How can I resolve this problem

Answer
ERROR 13 (or ERR 13) could be caused by a low back-up battery which means your presets could be erased.  We recommend you to get the battery checked before you start to enter a lot of new presets. Please contact your nearest TC dealer for directions to an authorized TC cervice center.
