Connecting to a USB Device
You can connect a USB device or cable to the projector's USB-A port to project images from the device.
Use the USB cable supplied with the device.
Note: Do not connect a USB hub or a USB cable longer than 9.8 feet (3 m), or the device may not
operate correctly.
Make sure the USB device meets the following requirements:
• The device must be a USB flash drive, USB hard drive, a digital camera, or a microphone.
• The USB-A port is not guaranteed to operate all devices that support USB.
• You may need an app to project content from your USB device.
