*There are two ways to lower and raise the projection screens and window shades in the classrooms: 1) via the wall controls

*The wall controls for the screens have up and down arrows and a stop button. They are laid out as they are positioned in the rooms – the left button controls the left screen and so on.

*The wall controls for the shades are not marked and are three vertically aligned buttons. The top one raises the shades, the middle one stops the shades in either direction, and the bottom one lowers the shades.
