La Crosse Technology WT-3181 - Manual (Page 5)

TEMPERATURE AND HUMIDITY
The La Crosse Technology clock has two analog sensors that measure surrounding temperature and
humidity. The temperature information is displayed in degrees Fahrenheit and Celsius, and humidity
data is displayed in percentage.
The thermometer and hygrometer have been calibrated in factory. To check the sensors accuracy,
tune to your local weather forecast information broadcast for the latest weather information. It may be
necessary to adjust the sensors.
To manually adjust the sensors, gently turn the corresponding knobs located at the back of the clock
until required data has been reached.

TROUBLESHOOTING
The wonderful advantage of owning a La Crosse Technology radio controlled 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 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 Radio-Controlled clocks and other electrical appliances
that cause interference.
Weather - Electrical storms between you and Colorado during the night will interfere with the
WWVB signal.
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 in the fall.
ARIZONA AND INDIANA
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.
