year keeps resetting on at&t cl4940 phone
I have a landline home phone that uses an AT&T CL4940. Every now and then the year changes to last year's date, just the year, nothing else. I reset it manually and it's ok for a long time, then out of the blue it gets reset, but by whom? Why?
Also I get an odd msg about setting the Access Code. I checked it and it's what I set it to a long time ago,not the default anymore. Why the msg??
