³ Setting Up The Screen And Projector - NEC WT615 Guide D'installation

Setting Up the Screen and the Projector
1. Refer to "Throw Distance (C)" in the diagram and use a distance between the screen and projector that corre-
sponds to the screen size.
As an example, when projecting to a 60" screen, set the projector with a separation of approximately 10.4"/26.3
cm from the screen.
2. Refer to "Height (D)" below and adjust the screen height, or adjust the height of the projector stand.
As an example, when projecting to a 60" screen, adjust the height from the feet of the projector to the lower
edge of the screen to approximately 19.0"/48.2 cm.
