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.
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 = 1.67 to 2.00
B = 1.2 to 12 m (4 to 40 ft)
C = 0.21 to 0.45

Setting Up
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 back of the projector and the other end 
to an electrical outlet.
3. When you first turn on the projector, set it to match the installation, if necessary. 
Open the on-screen menu 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 53.
To connect power
■Connect one end of the power cord to the back of the projector 1 and the other 
end to an electrical outlet
