I have a freedom phone GH4102 which is not working but gives me a message that it is "out of range". I have not moved it from it's previous base. I was moving the phone and needed to put a longer cord between the base and the wall jack. When I plugged it in I got this message and the phone has not worked since. The charge light goes on so I assume the batteries are working. I currently have a corded phone and get good service on the line. How do I go about resetting the freedom phone?
