Selecting the Connected USB Source

You can switch the projector's display to the source you connected to one of the USB-A ports. To display the connected USB device, select the USB1 source.

Note: If you have connected a document camera using a USB cable, select the USB2 source.

Make sure the connected USB source is turned on, if necessary.
Press the USB or Source Search button on the remote control and select the USB1 or USB2 source.
