If you have a clock model 86715, 86730 or 87315 and your clock did not change for Daylight Saving Time, what you should do is change the location of the clock to give it better access to the signal. Put it in a window with the face of the clock pointing toward Colorado or leave it in a car overnight until it changes.
If moving the clock doesn’t help, then take out the batteries for 10 minutes. When you put them back in, place the clock in a window with the face of the clock pointing toward Colorado and leave it there overnight. The clock should pick up the signal overnight and set itself by morning.
You may change the clock manually. Refer to this Quick Reference Guide for instructions: http://skyscanatomicclocks.com/site/quick-ref/
If you continue to have problems you should consider upgrading to a current model clock.
