Reflecting the Image
Using a mirror to reflect your projector's image enables
you to enjoy a much larger image when a smaller space
is required. Contact your NEC dealer if you need a mir-
ror system. If you're using a mirror system and your im-
age is inverted, use the MENU and SELECT buttons on
your projector cabinet or your remote control to correct
the orientation. (
