Uniwell DX-895 Programming help

Hey guys,

I was helping my boss re-program/organize the till better, however we have come into a situation and have gotten stuck. We have the engineer code, however we deleted one part of the menu and are unsure on how to add it back in, along with the log off button. I tried adding the log off button back in, however it just beeps when pressed.

We are sort of urgent on getting this done as one part of the menu is gone and we're open early tomorrow.

Thank you for any help,

Oliver
