message light flashes continuous 0 & then the letter C. How do I stop this ? Just purchased machine & I have the manual but can't find anything to resolve this problem. When first set up this did not happen until there was a power interuption. I then checked all settings including date & time. I also tried turning answer off then on again & also disconnected power to see if it would re-set. The machine works fine, just annoying flashing . Thanks
