From your picture, it looks like the chair is level so I am unsure why it would display a “4”. However, if it is unlevel you can manually level it by turning the leveling motor shaft. That may not solve the problem though. It could be a programming issue and the chair is unsure of where it is on the railing. In that case, you would need to set the “datum” point by running the chair in programming mode. You can find out more here: http://okprops.com/how-to-problem-solve-an-acorn-180-or-bison-80-stairlift/
