Get Started 

 

Step 1: 

Remove the round battery cover from the back of the clock.

 

Step 2: 

Insert 1 fresh AA, LR6 1.5 volt ALKALINE battery according to  

             the polarity marked on the case. Replace the battery cover. 

Step 2:

 Firmly press the time zone button once. 

Step 3:

 Position the clock on an exterior wall that faces Ft. Collins,  

             Colorado. During the night, your clock will automatically set itself. 

Note:

 The hands will move to the 12:00, 4:00 or 8:00 position and 

search for the radio signal. If the radio signal is received the time 
will set.  If the signal is 

not

 received the clock will stay at the 

12:00, 4:00 or 8:00 position and search for the WWVB time signal 
on the even hours. Once the radio signal is decoded, the hands 
will automatically adjust to the correct time. This may take up to 5 
nights. 

Step 4:

 The default time zone is Pacific Time. If the clocks sets itself and  

             the hours are off, hold the correct time zone button for 5 seconds  
             to correct.
