For the purposes of saving energy and money, we ask that all instructors turn off classroom projectors when you are finished using them.  Of course, if you know the next instructor is outside waiting, feel free to keep the projector on. If you know the next class won’t be using the projector for 20-30 minutes or later, please turn off the projector. 

Below are instructions for turning off the classroom systems. Please note that pushing the “mute display” button on the control screen will cause the projector to project a black image and will still use up some of the bulb’s life. (For most of our projectors, the bulbs run around $300 each. In the case of room 172, the bulb is around $800.)  Thus, when you leave the classroom for more than a few minutes, it’s much better for the system to turn the projector all the way off rather than muting it.

1) Wave your hand by the touch screen on the lectern. The little dot my finger is pointing at the motion sensor that will turn on the touch screen for you.

2) Press the System Off button.

3) When asked if you are sure you want to turn the system off, press on the Power Down button.

Here and there the Power Down button may not work exactly as intended and the projector will stay on. If that’s the case, please let us know at con-it@osu.edu and we can take a look.

If you are coming into a classroom and wanting to turn the projector on, first make sure that the computer is on by looking under the monitor and checking for the lime green light:

If the computer is not on, you can turn it on by pressing the green button once. The machine may take a few minutes to start up.  Again, wave your hand in front of the sensor and the touch screen should turn on. You can use the touch screen to turn on the projector as well as changing the input (from the classroom computer to a laptop, for example).

Please let us know if you have any questions about using the classroom computers, turning on/off the projectors, etc.  Also, please remember to lock the classroom doors when you leave.
