How do I project images from a USB device?
You can use the projector's PC Free feature to project compatible images or movies from a USB storage device. Connect your USB device or camera to the projector's port and switch the projector's display to this source. When you're done projecting, make sure you disconnect the device from the projector correctly. Turn off the device and unplug it, if necessary, and then disconnect it.
The devices must be USB-mounted devices, not TWAIN-compliant devices, and must be USB Mass Storage Class-compliant.
