What is the purpose of the docking unit?

The Elura 2, the Elura 2MC, the Elura 10, and the Elura 20MC are very small and highly portable units. In order to keep this compact size, the docking unit is a separate device which provides additional connectivity that is not normally needed. The docking unit connects physically and electronically with the Elura camcorder, and provides connections for an external microphone, earphones, S-video, and a LANC terminal (which provides connection to other LANC-compatible devices.)
