TROUBLESHOOTING 
  

LOW BATTERY INDICATOR 
 

The watch is supplied with, and powered by a high quality 3V lithium battery 
with a life expectancy of over 2 years.  There is a low-battery indicator that 
appears between the minutes and the date when the battery is low.  The 
battery should be replaced within 2 months of the appearance of the low-
battery indicator.  

 

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. 

MAINTENANCE AND CARE 
 

Under normal conditions, the watch is shock resistant, however avoid 
excessive “rough” treatment of the watch as this may cause serious damage.  
Clean the watch with a soft dry cloth, or with one moistened with a mild soap 
solution.  Do not use any chemical cleaning solutions, these may cause 
permanent damage to the watch’s surface.  While the watch is water resistant 
to 100 feet, do not submerge in water for extended periods of time.

ADJUSTING THE STRAP 
 

The rubber strap is adjustable to fit most all wrist sizes. It is also 
replaceable with a properly sized band available at a local watch or 
department store. The strap is held in place by a pin on each side.

The battery can either be replaced by a qualified jeweler or watch repair shop,
