button, normal operation 
resumes.

Presenting a Slideshow (EX51/EX71

You can use your projector’s Slideshow feature whenever you connect 
a USB device that contains .JPG image files. This lets you quickly and 
easily display individual images, or start a slideshow of all the images 
in a folder. You can control your slideshow using the projector remote 
control.
For an instant PowerPoint presentation, convert your PowerPoint 
slides to individual .JPG files (save as *.jpg) and store them in a folder. 
Copy that folder to a USB flash memory drive (thumb drive), or other 
USB device. Then connect the device to the projector and begin your 
presentation.
You can switch the display from the device displaying the slideshow to 
another source using the 
Search button or one of the specific Source 
buttons on the remote control. To return to the Slideshow source, 
press 
Search and select USB, or simply press the USB button.

resolutions up to 
8176 × 6144, with pixel 
counts incrementing in 
multiples of 8.
If a .JPG file is highly 
compressed, your projector 
may not be able to display it 
correctly. The projector can’t 
display progressive .JPG
