and computer with the provided interface cable, and transfer the

than the EOS DIGITAL camera-dedicated Canon interface cable 

.

Connect your camera and computer directly with the interface cable 
provided with your camera. Do not connect the camera via a hub; 
doing so may prevent EU and your camera from communicating 
normally.



If you connect multiple USB devices (not including the mouse or 
keyboard) to your computer, the camera may not communicate 
normally. If the camera cannot communicate normally, disconnect 
USB devices other than the mouse or keyboard from your computer.

Do not connect more than one camera to the same computer. Two or 
more cameras may not operate normally.

Do not connect your camera with the computer while performing 
“Linked shooting” with a WFT series Wireless File Transmitter (sold 
separately). Your camera may not operate normally.



If there is insufficient charge left in the camera battery, the camera 
cannot communicate with EU. Either replace with a fully charged 
battery or use the AC adaptor kit provided with your camera. Your 
computer does not supply power to the camera through the interface 
cable.
