12” Atomic Wall Clock 

 

Get Started 

 

Step 1: 

Slide the switch to select a time zone. 

Step 2:

 Insert 1 fresh AA, Alkaline battery according to the  

             polarity marked on the case. 

Step 3:

 For the best reception, please place clock on a wall that  

             faces Ft. Collins, Colorado. 

During the night, your clock  

             will automatically set itself. 

 

 

When the battery is installed, the hands will move to the 12:00 
position and search for the radio signal.  

 

If the radio signal is not received in the first 10 minutes, 

the 

clock will start running from the 12:00 position

 and will 

continue to run.   

 

Do not attempt to reset the hands manually even though the 
time on the clock is incorrect.  The clock is synchronizing to 
the WWVB signal and once the radio signal is decoded, the 
hands will automatically adjust to the correct time. This may 
take up to 5 nights if there is atmospheric interference. 

 
 

Reset:

 If the clock does not respond to the various function 

modes, press the RESET button on the movement case.
