A configuration wizard steps you through the process of setting up the incoming lines and assigning handsets etc. I had the system operational in less than half an hour. The small Ericsson handsets have a nice readable screen and rest in a handy charging cradle. The base station should be located centrally away from possible interference. I couldn't get near the advertised 900 ft. range which I suspect is due to interference from these devices and other less than perfect conditions.
System features are extensive and the voice recognition is very handy.
You can set up all of your contacts so that they can be accessed by voice command. Most features can be accessed by voice or menu or keystrokes. The learning curve can be a bit steep because of all the options but that is the nature of these new technologies. They can do so much that the instructions get long and complicated. I tend to learn what I need to survive and then gradually add features as I discover the need for them.
