While the X16 sets the time on the phone each time a Caller ID is received, you will need to know how to setup the year if for some reason the day of the week does not match the date, I.e. the year is off.
Tom Grinde installed a new phone system as a real expert! He was thorough, efficient, knowledgeable and helpful. He gets an A+++++++++++from me. I will recommend him and Telco to others without reservation.Charles Colwell
