Samsung ?
I have the Manual But it doesn't say anything about repairs The register will add things before you finish typing in the item say I am typing in 2.35 pounds at 3.99 I will hit the 2 and before I can even hit the next key it has added .02 under some item also it will start beeping (Error sound) when noone is even in the room I have noticed it does it if you touch the case in a few certain spots as well.
