18 Using the Projector
Turning On Your Equipment
Make sure your projector and other equipment are set up and
connected correctly, as described in Chapter 1 or Appendix A. Then
turn on your projector, as described below, followed by any
equipment you’ve connected to it. You can turn on your computer
and video equipment in any order, but if you have both a computer
and video source connected, you may have to switch to the desired
source as described on page 20.
Turning On the Projector
Follow these steps to plug in and turn on the projector:
1. Connect one end of the power cord to the projector’s power inlet.
2. Connect the other end to a grounded electrical outlet.
The power light on top of the projector turns orange, indicating
that the projector is receiving power but not yet turned on.
3. Use the tab on the lens ring to rotate the ring and extend the lens.
