    User Supplied Computer

    Do not turn on the laptop until the Step 3 cable connections are complete as described below.

    A VGA cable with audio line is provided for connecting the user supplied laptop to the VGA jack in the wall. In many rooms, this cable is permanently attached on the cabinet end.

    Laptop users may need to provide a cable adapter specific to their model laptop.

    1. Connect the cable to the laptop following the manufacturer's instructions. The cable end with the long audio line (Figure 1) is plugged into the laptop.

    1. Power up the laptop. The laptop should detect the running display and configure itself.
    2. If the laptop was started prematurely or it is not displaying on the projection screen, restart the laptop. Call the IT Help Desk at x4-HELP (x4-4357) for assistance if the restart does not correct the issue.

    3. Adjusting The Volume

    Use the volume adjustment knob to adjust volume levels. A flashing volume indicator light means that adjustment has reached the end of the adjustment range. It is recommended you turn it all the way down until your source is running, as different sources have widely varying volume levels.

    The projected image and the sound can be separately and temporarily be shut off without turning off the projector. Pressing "PIC MUTE" or "AUDIO MUTE" once will mute the picture and sound respectively. Pressing either again will end the muting of the picture and sound respectively.

    5. Turning Off The Projection System

    To power down, projector PRESS and HOLD the "OFF" button until it starts flashing.

    Please shutdown the computer when you are finished.
