Problem: The screen is black, and pressing different items on the touch panel doesn't do anything
The most common reason you see this behavior is the person who used the AV equipment before you turned on Picture Mute. To turn Picture Mute off, tap the System Tools button.
Then, make sure Picture Mute is OFF for any/all projectors.
If you're still having trouble, call (757)594-7079 and tell the person that answers that you're currently using a classroom.
Problem: No Sound is Coming from the Classroom Speakers
The first thing you should check is that the system isn't muted at the touch panel (the button will read "Mute" if it is, and "Unmute" if it is).
If that doesn't work, the computer may have selected an incorrect audio output. To change the output, click the volume icon in the taskbar.
Then, click the arrow at the top to change outputs.
Choose the one including "Crestron" and the audio should go through the classroom speakers.
If you're still having trouble, call (757)594-7079 and tell the person that answers that you're currently using a classroom.
Problem: The monitor is displaying icons, but the projector is not.
The display has been switched to "Extend" mode. To switch it back, right-click on the desktop and choose "Display settings.”
Change the dropdown under "Multiple Displays" to "Duplicate these displays."
If you're still having trouble, call (757)594-7079 and tell the person that answers that you're currently using a classroom.
Problem: The document camera is not displaying or is frozen
Double-check that the document camera is on by pressing the power button on the camera. A green light will be lit if it's on.
Double-check the zoom level of the camera with the zoom wheel.
If the image is frozen, ensure you don't have "Freeze" activated.
Problem: I need to access something in the cabinet, but it's locked, and I don't have a key
The lecterns are supposed to be kept locked at all times. If you've been issued a key for ANY standard lectern, it will work on all lecterns on campus. You can get a key issued by submitting a ticket via help.cnu.edu to request key training. Unlocking lecterns for others or giving your key to others is prohibited
