one or more of the following:
■If your image looks like   or  , you’ve placed the

							28Using the Projector
Shutting Down the Projector
When you’ve finished using the projector, follow the recommended 
procedure to shut it down. This extends the life of the lamp and 
protects the projector from possible overheating. 
1. If you’re using a computer, shut it down first.
2. To turn off the projector, press the 
Power button on the 
projector or remote control. You see a confirmation message. (If 
you don’t want to turn it off, press any other button.)
3. Press the 
Power button again. The power light flashes orange for 
about forty five seconds as the projector cools down. When the 
projector has cooled, the orange light stays on and the exhaust fan 
shuts off.
If you want to turn the projector on again, wait until the orange 
light stops flashing. Then press the 
Power button.
4. Retract the front feet as shown.
note
When the projector has not 
received any input signals for 
30 minutes, it automatically 
turns off the projector lamp 
and enters “sleep mode.” This 
conserves electricity, cools the 
projector, and extends the life 
of the lamp. If you are done 
using the projector, unplug 
the power cord. If you want 
to start projecting again, press 
the Power button. MenuA/V Mute

Using the Remote Control as a Wireless 
Mouse
When you use the remote control as a wireless mouse, you can control 
your computer or click through slideshow-style presentations (such as 
PowerPoint) from up to 20 feet away. This gives you more flexibility, 
since you won’t need to stand near your computer to change slides, for 
example. 
To control your computer with the remote, make sure you have 
connected the mouse cable between the projector and your computer 
as described on page 13 (for laptops) or in Appendix A (for other 
systems).

screen and use the directional buttons to move the cursor. 
■To click (or left-click), press the Enter button.
■To right-click, press the Esc button.
■To double-click, press down twice on the Enter button.
■To click and drag, press down on the Enter button and use the 
directional buttons to move where you want to drag.
