General projector remote control notes
On the projectors remote control, you will select your source, either video (DVD/VCR) or PC
When the projector is on, if you want to temporarily not display your signal, press either the "no show" or "AV mute" button on the remote to hide the projected image
If not all of the computer's image is showing up, try pressing the "auto set" or "auto PC" button that is in the upper left of the remote on many models. It does an automatic adjustment of the projector to the computer's signal. If it makes some improvements but not all, try it a second time.
The "screen" button will cycle you thru various screen aspect ratios and sizes that may give you the image you want
To project an image from video or the computer
Point the remote at the projector on the ceiling and press the power button. The power light should change. Some projectors make fan noise right away, some don't. All of them take about 30 seconds to warm up, after which you will see which signal (either PC or video) the projector has feeding into it.
All projectors will turn on to whatever they had been displaying last. So if the last person had the projector using the computer input it will return to that input. If the the last person used the video input it will go to that. Wait until the projector is fully on and then if it is not showing your desired source, change it, change to either video or PC. If you do this before the projector warms up and it was already on the computer input and you press computer again, it might change to another type of computer input.
For audio, turn on the audio amp and select either "Video" or "computer" as the input. Make sure the red “tape” light is not on. If it is, press the “tape” button to turn it off. Also make sure the selector for “Speakers A” is on and not “Speakers B”.
When finished, turn off the projector with the remote. When you press the power button button the first time on the remote, it will ask you again if you want to turn off the projector, so you will have to press the power button again.
Turn off any other equipment in the cabinet that you turned on.
For most presentations you can leave most of the lights on, although you will probably want to turn off the front row of lights. The “Dwight principle” says that the darker the room is the more likely students are to fall asleep.
If you want to hookup a laptop to the system, use the VGA cable by the computer and via the switchbox, change from PC to Laptop. Please change it back to PC when you are done
