Note: 

The unit will still try and receive the signal every day despite it being manually set. When it does 
receive the signal, it will change the manually set time into the received time. During reception 

attempts the WWVB tower icon will flash. If reception has been unsuccessful, then the WWVB tower 
icon will not appear but reception will still be attempted the following hour. 

 

WWVB time reception takes place from 12:00 am through 6:00 am each day (attempts WWVB 
reception every full hour within this  time frame). When the time signal is received for example at 1:00 
am, the atomic clock will not attempt to receive the WWVB signal for the remaining hours until 6:00 
am. Therefore, the next signal attempt will take place between 12:00 am and 6:00 am the next day. 
The other times WWVB reception takes place, are upon setup and after manual time set exiting 
mode. Reception is generally not possible during daylight hours due to the interference of the sun.
