Work Light

Audio Controls

Save Your Ears: Devices may also have their own volume control. Turn volume all the way down and bring it up gradually to the desired level. Some players, YouTube for instance, may also have their own volume control.

The Program Audio controls raise and lower the volume of computers and other devices connected to the display.

1. Press Up Arrow or Down Arrow to raise or lower the volume.  

2. Press Mute to silence the sound.

Program Audio or Room Audio volume does not affect microphone volume.

If a room has wireless microphones look for the Microphone Control button to adjust the level of individual microphones.


Check your classroom for available microphones. Most smaller classrooms have a microphone in the ceiling tiles or a button microphone on the teaching station. In some classrooms, wireless microphones may be stored in a drawer. Use the Microphone button on the touch panel to turn the mic on or off.

If a classroom has wireless lapel and handheld microphone they will be stored in a locked drawer in the teaching station.

  • Press Unlock Mic Drawer to open the drawer and access the wireless microphones
  • Press Microphone Control to adjust the level of individual microphones
  • If there is more than one microphone in the classroom, Mic 1 is the lapel mic.
  • The Program Audio volume control does not affect microphone volume.

Microphone Batteries

  • Fresh batteries can be found in the microphone drawer; They are wrapped in plastic
  • Do not use loose batteries found in the drawer
  • See diagram for battery replacement. The batteries in our microphones face the same direction (positive at the same side)

Camera Control

The majority of centrally classrooms have been outfitted with a camera to use for video conferencing or recording, and more will be added in the future.

You can choose a preset camera shot or adjust the camera shot from the Crestron touch panel.

  1. Press Camera Control
  2. Choose a preset that works for you
    • The preview window on the Crestron touch panel will show you the camera shot in real time.
  3. Use the arrow buttons to pan and tilt the camera
  4. Use the zoom buttons to zoom in and out

Note: The camera is slow to respond to the button presses on the panel. After making a single short press on a button, wait for the camera to respond  before pressing the same button or another.  Pressing too often or holding the button may cause the camera to swing/zoom too far.

If a classroom has more than one camera, the camera highlighted in green is the active camera. This camera will be recorded or used in a video conference.

Common Questions

Why is there no image projected?

Make sure the device you are using, such as the Internal PC, is powered on.

Make sure the projector is turned on with light coming out of it.  Press the Projector On button if it is off. If the projector is on, press a different input, wait a few seconds and press the desired input.

Why can I see light in the projector lens but there is no projected image?

Check to see if Video Mute button is pressed or flashing. This setting will prevent the image on your device from being displayed on the large classroom screen.

Why isn't the microphone working?

Make sure the microphone is powered on. If necessary, locate spare batteries in the teaching station.

Why is there an image on the projection screen, but not on the teaching station monitor?

Make sure the monitor is turned on. Look for the power button on the lower right-hand corner of the monitor.
