Daylight Savings Know-How!
For all Marathon Self-Setting ATOMIC clocks, just allow 24-48 hours for your clock to automatically adjust. For faster synchronizing, place your unit near a window or in a space with good reception.
NOTE: Do not manually reset your ATOMIC clock while it is adjusting!
For all standard Digital and Analog clocks and watches, don't forget to manually reset the time and change your batteries.
