I have had this model for close to 10 years. Approximately 2 weeks ago we lost our power for some minutes and now my AT&Ts' answering machine will not work for me. I have recorded my message to please call again several times but now I am not receiving any input. Can you help me? It has "Clock", "Set Up," "record and announce," and none of these work anymore. Please contact me at M.ferral@yahoo.com
