How do I reset all the items from the menu for the projector? I changed things because the the kids could not see the board and I want to start fresh. I must have messed things up because now the pens will not calibrate ( no reponse) and the screen is greyish and even less visable. I want it back to hwo it was before I messed things up. I think the zoom or slant maybe affect the pen location. I have tried two pens.
