Turning On Your Equipment
Make sure your projector and other equipment are set up and
connected correctly, as described in Chapter 1. Then turn on your
projector, as described below.
If you turn on your connected computer or video equipment before
starting the projector, the projector automatically detects and displays
the image source. If you turn on the projector first, or have multiple
pieces of connected equipment, you may have to select the image
source manually. See page 32.

1. Push in the tabs and remove the lens cap.
2. Connect one end of the power cord to the projector’s power inlet.
caution
Do not use the projector with
the lens cap in place. The
heat generated by the lamp
can damage it.
