Connect the EW3707 to a USB port on your computer. If you wish you can use the USB extension cable for more freedom of movement.
Connect the special plug (from which four cables extend) from the audio/video input cable to the EW3707.
Depending on what device you now wish to connect to the EW3707 (for instance a camera or video recorder) you can use one of the other four plugs of the audio/video input cable. See the image below:
Note! The coupling plugs shown in the image are supplied with the device you wish to connect. You will therefore not find them in the packaging of the EW3707.
