To turn on the projection system, locate the control panel behind the podium on the wall (stairwell-side) and press theĀ Power button. The light will begin flashing red as the system powers on. Once the power indicator light goes to steady red, the system will be ready to use. Please note: if you plan to switch inputs to another source (e.g. laptop), please wait an additional 10-15 seconds after the power indicator light goes steady red before pressing another input button as the system may still be finishing the startup process in the background.
