Using the controller

The Crestron touch panel controller looks like this:

A Crestron touch panel. Top left buttons, Bench PC. Laptop. OHP. Bottom left button, silence microphones. Top right button, Finish / turn off.

Sometimes when you enter a room the Crestron screen will be blank, to start just tap the screen for it to wake up.

To turn on the rooms projector you need to select one of the input sources (A). From here you can choose what is shown on the projector, either the lecterns PC (Bench PC), a external source such as your personal laptop using the lecterns HDMI or VGA cables (Laptop), or the lecterns video overhead projector/visualiser camera (VID OHP).

After selecting a source you will see a screen asking you to wait while the projector warms up to work. Once you have selected a source you can also change it to any of the other sources at any point by just selecting them.

If you wish to mute the microphones be it the Revolabs tie-clip mic or the lectern microphones, you can select the ‘Silence Microphone‘ button (B). The button will change to show ‘Activate Microphone‘ so you can be heard again.

At the end of a teaching session it is important to shut down the rooms projector unless someone else wishes to use it immediately after you. To do this select the ‘Finish‘ button (C) and then follow the prompt to turn the equipment off.

If you have used the tie-clip microphone, please make sure to replace it back into the dock on the lectern so it is charged and ready to use by the next person in the room.

Troubleshooting

You can always call ServiceLine on x25656 using the phone in the room for help. But here are some simple things you can check yourself to fix the problem quickly.

CLS Main display

  • Double check that you have selected the projector/display button to be on.
  • Make sure you selected the correct video source (PC, laptop, HDMI etc.) using the control panel.
  • On the Crestron touchscreen there is a Hide button. If it so, instead select the Show picture button.

Laptop video

  • Make sure the cables are securely plugged into your device.
  • On a laptop check you extended or duplicated the display. On a PC this is Windows + P.
  • Checked the correct display input is selected on the touchscreen/control panel.

Audio

  • Check that the volume on the PC or laptop turned up.
  • See if the volume on the room’s control panel is turned up.
  • On the Crestron touchscreen there is a Silence sound button, if so, select the Activate sound button instead.
  • If you are using HDMI, try disconnecting and reconnecting the cable, making sure that it is securely plugged in. Check that you have selected the correct audio output.

Revolabs wireless mic

  • Press the button on the front of the microphone or the button on the charging station to un-mute the microphone. The LED on both the microphone and charging station will flash GREEN to confirm that they are connected and working.
  • Press either button at any time to mute or un-mute the microphone. Remember, double-flash RED means muted, flashing GREEN means working.
