Unless you want to show up at work an hour early.

Yes! It's that time of the year again, when you go around your house, searching for all timekeeping devices to turn back an hour.  Isn't it exciting to gain an extra hour of sleep?

While we cannot help you with your VCR and microwave, we can show you how to set time on your Norstar Phone System:



Changing the time on a Norstar System must be done using a display phone. Using a Norstar M7310 or Norstar T7316 the right two buttons under the display are NEXT and SHOW respectively.  You'll need a Norstar Programming Overlay, which you can download a printable version here.
