TROUBLESHOOTING 
  

Problem: 

No WWVB signal (indicated by the absence of the WWVB tower icon). 

Solution: 

1) Check the selected Time Zone.  If it is set between GMT+1 and GMT 
+12, the WWVB signal will not be received.  Change the Time Zone. 
2) Move watch 10 feet (3 meters) away from any interfering sources, i.e. 
electrical appliances (refrigerators, TV’s, computers), metal surfaces or 
objects. 
3) To help with overnight reception, place watch in a window with the 
band inline with the general direction of Ft. Collins, Colorado.  
4) There are a few places the signal is very weak (Los Angeles area, Some 
parts of Florida and New York City). Since the watch has a much smaller 
receiver than our other clocks, it is possible no reception can be made. 
Please inform La Crosse Technology in this case. 

Problem: 

The watch displays “-:--” and no date 

Solution: 

1) The watch entered the power off mode and was reactivated. No signal 
has been located, and no time is set. Once the watch receives the time 
signal successfully (usually at night), it will display the correct time and 
date (Eastern Time zone is the default). 

Problem: 

The hour or minute is incorrect, even though the tower icon is on 
(indicating a successful reception of the WWVB time signal the previous 
night) and it is set to the proper time zone. 

Solution: 

1) Electrical interference caused the time signal to be improperly received. 
Be sure the watch is at least six feet from any source of electrical activity 
(television, computer). Overnight it should correct itself. 
2) You may need to perform a reset; follow the directions outlined in 
section IV.
