Setting Up
If you do not want to use the distance table, you can use the following equations to
help determine where to install the projector relative to the screen.
To set up on a table
1. Place the projector on a stable platform located 1.2 to 12 m (4 to 40 ft) in front of
the screen. Ideally, the platform should be lower than the bottom of the screen.
2. Connect one end of the power cord to the side of the projector and the other end to
an electrical outlet.
3. When you first turn on the projector, if the image is upside-down or backward,
you should change a menu setting. Open the on-screen menu (see “To change
settings using the on-screen menu” on page 37) and select Setup > Projector
position. Then choose Front Table from the drop-down list—this is the default
setting.
If you want to permanently install the projector on the ceiling or behind the screen, see
“Installing the Projector” on page 49.
Calculating projection dimensions
distance from lens to screen = A × width of screen
minimum and maximum distance from screen = B
width of screen = 0.8 × diagonal of screen (for 4:3 screen)
projector lens below bottom of screen = C × width of screen (for 4:3 screen)
A = 2.0 to 2.4
B = 1.2 to 12 m (4 to 40 ft)
C = 0.11 to 0.42
