You can use the remote control to click through slideshow-style 
presentations (such as PowerPoint

®

) from up to 20 feet away. 

This gives you more flexibility, since you don’t need to stand 
near your computer to change slides.

To change slides with the remote control, make sure you have 
connected your computer to the projector with a USB cable.

To advance slides in a 
PowerPoint presentation in 
Slide Show mode, press the 

Page up 

button on the remote 

control.

Press the 

Page down

 button 

to go back a slide.

The lights on top of the projector indicate the projector’s status 
and let you know when a problem occurs.

If the projector is not working correctly, first turn it off and 
unplug it. Then plug the power cord back in and turn on the 
projector. If this does not solve the problem, check the status 
lights on top of the projector and try the solutions 
recommended in the following table.
