Ok I have had my 522 for a little over 1 month now and a couple of time in the last couple of weeks I have turned the unit on and have been greeted with warning message. The warning states that the receiver needs to be connected to a phone line to prevent an additional charge for the 2nd outlet. I have exited out of the warning and proceeded to the diagnostic section and checked the phone connection no problem I have also checked the dial outs and none are pending. I called customer service and they asked if I had a modem connected to the phone line or if it was connected to a cellular phone. I told them no its a normal land line and I use cable internet so no modem connection only thing conneted to the phone line is a answering machine. The last call out was on 8/29 software L205 any ideas they told me if it continues to call the installers tech suport line and have them check the receiver. I guess this is just another problem in the long list of bugs in the 522.
