This morning my wife noticed that our SkyScan Atomic Clock (Model # 86722ALU) was not displaying the outdoor temperature.  After replacing the batteries in the temperature transmitter and the clock, I couldn't remember how to set the silly thing. 

With the help of Google, I found the instructions .

Even though my clock has a Skyskan label, this clock from La Crosse Technology could be its twin. [via Amazon]
