When I plug it in & charge it I am at a loss as to how to set it up and/or make a call it shows a channel & the number changes the more hit the button that says enter on top & channel on the bottom. Also, when I hit the phone button & put in a number I can't do anything with it I hit enter & it disappears. Basically I do not know how to do anything. I would appreciate any help you can give me.
