turn the DST “OFF”.

MANUAL TIME SETTING  

 
In case the atomic clock is not able to detect the WWVB-signal (disturbances, transmitting distance, etc.), the 
time can be manually set. The clock will then work as a normal Quartz clock. 
 

Note

:  In 12 hours mode the time will be displayed with an additional 

PM

 for the time from 12:00 noon until 

11:59 pm.

“Year Setting”

 

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. 
 

YEAR SETTING 

 
The year can be selected sequentially from 2000 to 2049 and will then start over again (default setting 2000). 
Only the last 2 digits of the year will be visible on LCD2.
