 1. Remove the round Battery Cover to access the Movement. 

2. Insert 1 AA battery into the Center Battery Compartment. 

    Optional: Insert batteries into the Extra Battery Compartments.

    IMPORTANT: Be sure all batteries are of the same voltage level. 

3. The hands will move to either the 4, 8, or 12 o’clock position and 

    stay there while it searches for the WWVB Atomic Time Signal. 

    Allow up to 5 nights for the clock to receive this transmission.  

4. For the best reception, place the clock on an exterior wall near a 

    window with the front or back of it facing Fort Collins, CO. 

5. Once the Atomic Time Signal is received, the clock will set to   

     Pacific Time. Firmly press and hold your correct Time Zone 

     Button until the hands begin to spin. The time will then set 

     correctly. 

6. If you live in an area that does not follow Daylight Saving Time, 

    while the hands are spinning to the correct time, press the 

    Daylight Saving Time Button once to turn the DST setting to OFF.   

Note: 

In certain areas, this clock may not be able to receive the 

WWVB reception due to signal strength or interference. In this case, 

your clock can be set manually until the Atomic Time Signal can be 

received.
