Connecting a Laptop (HDMI)
Each podium is equipped with an HDMI cable and laptop charging power outlet, as illustrated in the photo below.
Connect the laptop using the HDMI cable. After connecting the laptop, tap the Laptop button on the Extron touch panel. Tap the LAPTOP (HDMI) button to confirm the input selection. While this input is labeled Laptop, it can be used for any device that can connect over HDMI, such as a tablet.
After connecting the laptop, the viewing settings may need to be adjusted. On Windows 10 and Windows 11 computers, select the Windows key and the P key at the same time (Win+P) to bring up options to duplicate the display, extend the display, or select only the laptop screen or the projector screen for viewing while the laptop is connected.

Using the Camera and Microphone
To use the video conferencing system (the camera and microphone), the PC source must be selected on the touch panel. Only the PC is connected to the camera and microphone, and the equipment cannot be used by other devices connected via the HDMI cable or ShareLink.
Once PC is selected, press the Start Cam/Mic button to turn on the camera and microphone since they are not on by default. Once the video conferencing system is on, the camera and microphone will have green lights on them. When they are off, the camera will face the wall and the microphone will have a red light.
In your video conferencing application, ensure that the speakers are set to use the ExtronScalerD (Intel(R) Display Audio) and that the microphone is set as the Speakerphone (Extron MediaPort 300). In Zoom, pictured below, check the audio settings by clicking the (1) Up arrow (^) where it says "Audio." You can also click the (2) Audio settings... button to open the full Zoom audio settings.
The camera can be tilted up or down, or panned left or right using the (1) arrow buttons. To quickly reset the camera to its default position and zoom press the (2) home button. To zoom in or out, use the (3) plus (+) or minus (-) buttons. To quickly change to a predefined position and zoom, press one of the (4) numbered presets. One preset is a close-up of the podium, one is a close-up of the center whiteboard under the projector, and one is a wide, centered shot of the whole room.
The microphone can be muted or un-muted using the (5) Mute button. To control the microphone's volume level, refer to Adjusting Program and Microphone Volume Levels.
The video conferencing system can be turned off by using the (6) Shutdown Cam/Mic button.
Adjusting Program and Microphone Volume Levels
Adjusting the program volume level in the electronic classroom can be accomplished through the Extron touch panel.
The program volume level - what is heard through the room's speakers - can be adjusted using the (1) arrow buttons. The up arrow increases volume, while the down arrow decreases volume. The (2) Mute button will mute the audio. When using the Dell OptiPlex PC installed in the classroom or a laptop, verify that the audio output on the computer is not set to mute or off as well.
The microphone volume level - how sensitive the microphone is to noise - can be adjusted by clicking Mic Controls. The Mic Controls page has separate arrow and mute buttons for the program volume level and microphone volume level. Click the Close button to return to the main screen on the touch panel.
Projection Mute
The video signal to either projector can be temporarily turned off by selecting Mute under "Display 1" or "Display 2" on the Extron touch panel. Select Mute again to restore the video signal to the projector.
Blu-Ray Player Control
Select Blu-Ray on the touch panel to switch to the input. Control the device by using its remote or with the device's built-in controls. Also, verify the Blu-Ray player in the rack is powered on.
Document Camera Control
Select Doc Cam on the touch panel to switch the video signal to the document camera installed at the podium. The power button on the document camera is located on the top of the device in the top left corner. The other buttons control the viewing of documents.

It is available for use while using the PC input of the touch panel. Its sensitivity can be adjusted by clicking Mic Controls on the touch panel and using the arrow or mute buttons under "Microphone".
