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.
