Select the media to be used (desktop PC, laptop, visualiser, video) for the presentation by pressing the corresponding button on the media switch.
Once a button is pressed, it will start flashing until the projector has gone through its warmup phase before the image appears. While flashing, please desist from pressing any other buttons.
To connect a laptop to the AV system, plug in the DVI and 3.5mm cables, duplicate the laptop screen and press the Laptop button on the media switch.
An external device with RCA cables (camera or DVD/video player) can be connected to the system using the cable interface – push the Video button to show it on the projector screen.
The volume of the speakers is controlled by the Volume Up and Volume Down buttons on the media selector.
Ensure the Dell PC or laptop audio is not muted and turned up if the presentation contains an audio component. The computer volume control is by way of an icon on the taskbar at the bottom right of the PC screen. Hovering over the speaker icon will show you the volume as a percentage of maximum volume. Click on the icon to adjust the volume.
Please remember to press the Off button before leaving the room, unless of course the next lecturer/presenter is already present.
