                     The views are organized in presentation modes. Which presentation mode to use is selected with the tabs at the bottom of the EK80 presentation.

                     Modern computers can easily feed more than one display.
                        The Add Window dialog box makes it possible to create a new window for a dedicated echogram presentation. The new window can contain a copy of an existing echogram channel, or it can be used to present a channel that is currently
                                 not visible.
                        The window can for example be placed on a second (or third) display connected to your computer. 
                        
                        Select Add Window to open the dialog box. Select which channel to place in the new window.
                        In this context, the term channel is used as a common term to identify the combination of transceiver, transducer and operating frequency.
