Troubleshooting

The following are common problems that you can solve.

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.

Open

System Tools

• Then, make sure Picture Mute is OFF for any/all projectors.

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).

Open

• 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.

Open

• Then, click the arrow at the top to change outputs.

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
