WT-967 WWVB—RADIO CONTROLLED WATCH
ABOUT WWVB (Radio Controlled Time)
The NIST (National Institute of Standards and Technology—Time and Frequency
Division) WWVB radio station is located in Ft. Collins, Colorado, and transmits the
exact time signal continuously at 60 kHz. The signal can be received up to 2,000
miles away through the internal antenna in the La Crosse Technology watch.
However, due to the nature of the Earth’s Ionosphere, reception is very limited during
daylight hours. The Watch will search for a signal every night when reception is best.
The WWVB radio station derives its signal from the NIST Atomic clock in Ft. Collins,
Colorado. A team of atomic physicists is continually measuring every second, of
every day, to an accuracy of ten billionths of a second per day. These physicists have
created an international standard, measuring a second as 9,192,631,770 vibrations of a
Cesium-133 atom in a vacuum. This watch is regulated by the WWVB transmitter.

SET-UP GUIDE, FEATURES, AND OPERATION
TIME LCD
SET-UP
Your new radio-controlled watch may arrive to you already set. The default (factory)
setting is Eastern Time zone, Daylight Saving Time On and 12-hour time format. You
can tell if your watch has received the WWVB signal by looking for a tower icon in
the upper right corner of the LCD display. If the tower icon is solid your watch has
received the signal and set the time and date. If you need to set your watch to any
other setting than the default or need to manually activate the WWVB search (only do
so if there is no tower icon in the upper right of the LCD) please follow the directions
that follow.
NOTES:
• Do not press the TIME ZONE button while the watch is searching for the
WWVB signal, which normally takes 6-10 minutes.
• If you are unable to receive the WWVB signal during the daytime please
manually activate the WWVB search (see section II).
• The optimal time for WWVB reception is between midnight and 6:00 a.m.,
reception may not occur until this time period.
• When the WWVB search is complete the time and date will automatically be
displayed in the LCD.
• If the watch is not within range of WWVB signals for an extended period of time
it will still continue to operate as a accurate quartz controlled watch.

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 lowbattery indicator.
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.
REPLACING THE BATTERY
The battery can either be replaced by a qualified jeweler or watch repair shop,
or by the user.
Any damage resulting from this procedure is not covered under warranty .
1. Remove the four screws located
on the back and remove the cover.
Be sure the watch movement and
gasket do not come out of the
case.
2. Remove the old battery by gently
prying up the battery clip.
3. Insert a new battery of the type
“CR1620” 3 Volt Lithium Cell
battery
4. Please dispose of the old
battery properly.

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 because the watch is
programmed not to search when outside of the range of the WWVB signal.
Change the Time Zone to one of the time zone of the U.S and the watch
will again search for the WWVB signal overnight.
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 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 ten feet from any source of electrical activity
(television, computer). Overnight it should correct itself.
2) You may need to perform a manual WWVB search. Please follow the
directions outlined in section III.
