TROUBLESHOOTING  

NOTE:

 For problems not solved, please contact La Crosse Technology via e-mail or 

phone, or visit our website, www.lacrossetechnology.com

 

Problem: 

The time and date will not set initially. 

Solution: 

It usually takes overnight before the clock can receive the signal due to the 

interference the sun has on the WWVB signal.  Wait overnight for the signal. 

Solution: 

Computer monitors and televisions can cause interference with the signal 

reception. Please keep the clock at least six feet from electrical sources. 

Solution: 

In some areas of the US, in particular on the East and West coasts, the signal is 

very weak. It may take up to 72 hours before a good signal is received. The reception can 
be helped by placing the clock in a window facing Colorado, with the back towards 
Colorado. 

Solution:

 Be sure the time zone is set to a US time zone.
