LOW BATTERY ICON
When the battery of the digital clock needs to be replaced, the low battery icon will
appear on the LCD section of the digital clock.
DAYLIGHT SAVING TIME
The National Institute of Standards and Technology and WWVB encode a special
DST “bit” in the WWVB transmission for DST. Your La Crosse Technology® clock
will read this information and automatically advance the hands one hour in the
spring and eleven hours (to go back one hour) in the fall.
ARIZONA
If you live in an area that does not recognize DST you must press the (unmarked)
DST button for one second to deactivate your clock’s DST program. To reactivate
the DST program simply press the DST button again for one second.
FREQUENTLY ASKED QUESTIONS
Q. Will the digital World Time display also set ahead or back one hour for DST?
A. Yes, if you have DST set to “ON”. (By default DST is set to “ON”.) If the digital
World Time display is set to a foreign time zone for a country that has not
adopted the same DST dates, you will need to manually set the LCD.
Q. How long will the battery last?
A. A good AA alkaline battery will last over one year. If your clock is located in an
area with little interference where it can quickly receive a signal the battery can
last much longer than one year.
Q. Can this La Crosse Technology® clock be used outdoors?
A. No. Outdoor use is not recommended for this clock.
Q. Can the La Crosse Technology® atomic clock be wired to control timing
circuits?
A. No.
TROUBLESHOOTING
The wonderful advantage of owning a La Crosse Technology® atomic clock is that
it is virtually trouble free. If the clock receives a clear signal it will set itself
perfectly.
If it does not receive a signal consider the following:
Battery - The La Crosse Technology® atomic clock must have a fresh
battery to receive and process the time signal.
Location - Try a different location, ideally near a window. It should be at least
six feet from computers, TVs, air conditioners, other atomic clocks
and other electrical appliances that cause interference.
Weather - Electrical storms between you and Colorado during the night will
interfere with the WWVB signal.
The clock seems to “take off”, or the hands start to spin, for no apparent
reason and then stop.
It is not uncommon for the clock to make a "correction", sometimes daily. This
happensif the clock gets ahead of itself by a fraction of a second. To correct
this, the clock will advance a complete rotation the next time it receives a
signal.
