Reposition the atomic clock with the front or back facing Colorado. 

 

Try a different location, ideally near a window. The clock should be at least six feet 

from computers, TVs, air conditioners, other atomic clocks and other electrical 

appliances that cause interference. 

 

Large buildings, metal roofed buildings and buildings or rooms full of electrical and/or 

radio equipment make it difficult to receive the WWVB time signal. 

 

CLOCK IS INCORRECT BY HOURS BUT MINUTES ARE CORRECT 

 

 

This is a Time Zone issue. Hold your Time Zone button for 5 seconds. The clock 

should correct itself. 

 

Check that DST is on. Press and release the small, unmarked gray button between the 

ET and CT button one time. 

 

DAYLIGHT SAVING TIME 

 

 

Dependent on your location, position of the clock in your home, and atmospheric 

interference, it may take up to 5 nights for the change from Daylight Savings Time to 

Standard Time and vice-versa to occur. 

 

Press the DST indicator once. If the indicator is OFF the clock will not change. (Default 

is ON). 

 

Check for fresh 

batteries

. Without proper batteries, the antenna will have a harder 

time picking up the signal. 

 

Position the atomic clock in a window (with the front or back) facing Ft. Collins, 

Colorado and leave for up to five nights. If you do not have a window facing this 

direction, position the clock near an outside wall and point the unit in this general 

direction.  

 

MANUALLY SET TIME 

 

 

Remove battery for 15 minutes and press the Manual Set Tab 20 times. 

 

After 15 minutes, insert the battery and allow the clock to spin to 12:00, 4:00 or 8:00. 

 

Hold the Manual Set Tab and the hand will spin.  Continue holding to reach the correct 

time. 

Note: You can only set the clock manually for about 2 minutes after inserting the 

battery. If the clock receives the WWVB time signal, this signal will override manually 

set time. 

HOW LONG WILL THE BATTERY LAST? 

 

 

A good AA Alkaline battery will last over 12 months.  

 

CAN I SHUT OFF THE WWVB SIGNAL? 

 

 

No.  If you manually set the time, when the clock receives a WWVB signal, that signal 

will override the manual set.
