Using the Classroom Computer & Epson 7250 Video Projector

Please shut off the video projector when not in use; replacement lamps cost $400 (no exaggeration).
Insure that all cables are correctly attached:
- Network cable (usually red or yellow) plugs into the wall jack labeled “network” and to the rear of the computer. This cable must be connected at the time the computer is switched on in order for the network to be detected.
- Video cable connects the video jack on the rear of the computer to the Computer 1 video jack on the rear of the projector (see illustration below).
- Audio cable connects the audio out jack on the rear of the computer to the Audio 1 jack on the rear of the projector (see illustration below).
- Video cable from the monitor connects to the Computer Out jack on the rear of the projector (see illustration below).

Note that the projector must be powered on in order for you to see anything on the computer monitor (as the monitor receives its signal from the projector). If the projector is operating, but the monitor remains blank, press the Computer button on the projector control panel (see illustration on the reverse side of this sheet) to insure that the projector is “looking at” the proper input.
Press the Power button (see illustration below) to begin using the Epson projector; there will be a 60-90 second delay before the lamp reaches full intensity. The power signal lamp will change from orange to flashing green during this phase.

To project the image from a laptop, connect the video cable from the video port on the rear of the laptop to the Computer 2 jack on the rear of the projector. Note that some laptops require that the cable be connected and the projector on before starting the computer in order to detect the external device. Press the Computer button on the control panel (see illustration above) to toggle between Computer 1 (classroom computer) and Computer 2 (laptop) displays.
To display the signal from the videotape recorder, first be sure that the cables from the VCR’s audio and video jacks are connected to the Video In and L & R Audio In jacks on the rear of the projector. Press the Video button on the control panel (illustrated above) and then begin playing your videotape. While holding down the Shift button, press the Volume buttons to adjust the level as needed.
