Reflecting the Image

Using a mirror to reflect your projector's image enables you to enjoy a much larger image. Contact your NEC dealer if you need a mirror. If you're using a mirror and your image is inverted, use the MENU button and SELECT dial on your projector cabinet or the MENU and the ￿￿￿￿

buttons on your remote control to correct the orientation. (See page E- 33.)
