WWVB Radio-controlled Time 

WWVB Icon will flash when searching. 

The WWVB icon will be steady when time signal  

received in the past 24 hours. 

 

For information about WWVB visit:  

www.nist.gov/pml/div688/grp40/wwvb.cfm  

ATOMIC SIGNAL SEARCH: 

The atomic clock will search for 1 hour between midnight and 6am until 

the WWVB time signal is received. After reception, the atomic clock will 

only search for the atomic signal after midnight. 

Moon Phase 

 

The LCD Moon phase is divided by 6 

sections, showing a total of 12 phases of 

the moon. 

Note

: With the moon shown against a light 

colored background, the phases will show opposite to a paper calendar. 

The segments that are highlighted will portray the part of the moon that is 

lit. For instance, the moon will be blank during a new moon and dark 

during a full moon.
