Thanks guys, yes, there is a "setup" key in the display. When the phone is hung up, when I hit it, it shows "Settings" in the display. The manual then says to hit the Enter key. As soon as I do, the display returns to the time/date display and a underline cursor appears. That's as far as I get. Nothing happens if I press any of the other keys.

justbill, I am aware of the two models. And the two phones I have are one of each type, and they can apparently be converted from one to another. Regardless, both seem to exhibit the sames issues so far. :confused:

I received an email from Bizfon, and they charge $89/call. I may opt to do that, but I find it unlikely that all 3 phones would be defective.
