Preparing the conference units for use

The conference units are ready for operation upon delivery. The conference system automatically recognizes if the connected conference units are chairman units or delegate units and initializes them automatically.

If you connect chairman units to the conference system during a running conference, you have to re-initialize them (see page 30 or page 88).
