

 

The clock must receive the WWVB Radio 
Signal to automatically set the time, date and 
weekday. 

 



 

The clock automatically starts the WWVB 
signal search after 7 minutes of any restart or 
changing of new fresh batteries. The radio 
tower icon starts to flash. 

 



 

At 1:00 am, the clock automatically carries out 
the synchronization procedure with the WWVB 
signal to correct any deviations to the exact 
time. If this synchronization attempt is 

unsuccessful (the radio tower icon 

 

disappears from the display), the system will 
automatically attempt another synchronization 
at the next full one hour. This procedure is 
repeated automatically up to total 5 times.  

 



 

To start manual WWVB signal reception, press 
the “WWVB SEARCH“ button. If no signals 
received within 7 minutes, then the WWVB 

signal search stops (the radio tower icon 

 

disappears) and will start again at the next full 
one-hour.  

 



 

To cancel RC reception and stop searching for 
the WWVB radio signal, press the “WWVB 
SEARCH

“ button once. The radio tower icon   

will disappear. 



 

 

A flashing radio tower icon indicates that the 

WWVB signal reception has started. 

 



 

A continuously displayed radio tower icon 
indicates that the WWVB signal was received 
successfully during the last attempt.  If the 
clock attempts to receive the WWVB signal and 
is unsuccessful, the tower icon will not be 
continuously displayed on the LCD. 

 



 

We recommend a minimum distance of 2.5 
meters (8 feet) to all sources of interference, 
such as televisions or computer monitors
