Connecting to Projector
As there is no computer in this room, an external device will be required to project from.
- Connect the HDMI cable to the device. This will allow screen projection and link the device’s audio to the room’s speakers.
- If using the built-in webcam, connect the webcam cable to the device.

Troubleshooting
No sound
- If there is no sound after connecting the HDMI cable, connect the AUX cable to the device as well. Refer to the image above for connections.
- On the device, check the sound settings. (still need photos of this?)
