*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.
