Luter Interim AV Guide
Due to the construction of the Science and Engineering Research Center, this room is temporarily using a non-standard AV system. This guide provides the necessary information to use the classroom effectively.
Available Equipment
TV for display
Document Camera
Lectern Computer (laptop)
HDMI Connection
Turning on the System
Tap the screen anywhere except the Clean Screen button in the top right. Tapping Clean Screen will lock the touch panel for 30 seconds.
Controlling the System
To start showing items on the TV, you’ll have to select them from the Source Select box on the left side of the touch panel.
To use your own computer, tap User Laptop and plug in your computer to the cable on the lectern.
To use the document camera, tap Document Camera. If you need instructions on how to operate the document camera, please see our full guide.
To use the classroom computer, tap Room Laptop and sign in as normal
You can control the volume of any media that’s playing through the system with the volume control at the bottom of the touch panel. Turning the volume to minimum will still have some sound playing. To completely silence audio, use the Mute button.
You can tap Video Mute to blank the screen, but not turn it off, allowing you to work on something you don’t want students to see or to create a distraction-free environment.
Video Freeze is similar to Video Mute, except it basically pauses the image on the screen when you tap Video Freeze. Anything that happens on the computer or document camera will not display. This is useful for queuing up survey questions or preparing the next item to display.
When you press Video Mute or Video Freeze, the audio is also muted. To play audio from a computer while keeping the screen muted or frozen, unmute the audio.
Turning off the System
When you’re done using the AV system, you’ll need to turn it off. Tap the power icon in the top right corner of the touch panel.
When you do, you’ll see a screen that asks if you are sure you want to shut down the room. Tap Yes.
If you used the computer in the room, you’ll also need to sign out. Click the Windows logo, click your name, then Sign Out.
Troubleshooting
The touch panel displays a partial green circle and isn’t responding
If Screen Clean is pressed, the touch panel is locked and a partial green circle displays.
The circle will gradually disappear. When it does, you’ll be able to use the touch panel again.
Sound is coming from the computer speakers, not the TV
Click on the volume symbol at the bottom of the screen.
In the window that appears, click the "Select a Sound Output" button.
From the menu that appears, select the choice that reads “HD Audio Driver for Display Audio”.
Nothing appears on the display
Make sure Video Mute is not active.
A screen that talks about diagnostics appears on the touch panel
If you see this screen, press Exit.
