If
you connected an additional image source to the projector, such as
a computer or DVD player, you may want to switch from one image
source to the other.
Make sure the connected image source you want
to use is turned on.
For video image sources, insert a DVD or other
video media and press its play button, if necessary.
Press the source button on the
projector or remote control. Press the up or down buttons to select
the image source.
Note: If no
image signal is detected, check the cable connections between the
projector and the image source.
