Powering up the Projector and Adjusting the Image
NOTE: Always use the power cord 
that shipped with the projector.
1
Remove the lens cap.
2
Plug the power cord into the side of the projector, then plug it 
into your electrical outlet. A surge-protected power strip is 
recommended.

Turn on the projector by pressing the “I” side of the power 
switch (see Figure 2 on page 3).

The startup screen displays and the Power LED on top of 
the projector lights up (Figure 11 on page 15).

If you connected a video player, turn it on.

The video image should display on the projection screen. If 
a computer source is active, press the 
source
 button on the 
keypad (page 15) to display your video image. You can 
select a default source to determine which source the pro-
jector examines first during power-up for active video; see 
“Default Source” on page 24.
•
Use the 
volume 
buttons to adjust the volume.

The computer image should display on the projection 
screen. (If a video source is active, press the 
source
 button to 
display your computer’s image.)
NOTE: With some computers, 
the order in which you power up 
the equipment is very important. 
Most computers should be turned 
on last, after all other peripherals 
have been turned on. Refer to your 
computer’s documentation to 
determine the correct order.
•
If necessary, make adjustments to the image from the pro-
jector’s on-screen menus. To open the menus, press the 
menu
 button on the keypad, then select the Display or 
Image sub-menu. For more information about the menus, 
see page 17.
