WWVB RADIO CONTROLLED TIME
The NIST radio station, WWVB, is located in Ft. Collins, and transmits the exact time signal continuously
throughout the United States at 60 kHz. The signal can be received up to 2,000 miles away through the
internal antenna in the Weather Station. However, due to the nature of the Earth’s Ionosphere, reception
is very limited during daylight hours. The Weather Station will search for a signal every night when
reception is best. The WWVB radio station derives its signal from the NIST Atomic Clock in Boulder,
Colorado. A team of atomic physicists continually measures every second of every day to an accuracy of
ten billionths of a second a 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 atomic clock regulates the
WWVB transmitter.
WWVB RECEPTION ICON with full signal strength will appear on screen in front of the date
when the reception of time is successful.
The tower icon will show solid when the Weather Station has received the WWVB signal.
No tower icon is shown. The Weather Station was unable to receive a signal at this time.
Reposition the Weather Station for better signal reception or try again at bedtime.
The Weather Station will start searching at UTC: 07:00 and if no reception on the first attempt they
will try again at 08:00, 09:00 and 10:00. Each attempt will be at least 2 minutes and the most will be
10 minutes.
If there is no signal or too much interference the receiver will only be on for 2 minutes.
If the signal is good it may catch a signal in ABOUT 2-3 minutes.
If the signal is marginal it will try to catch a signal for up to 10 minutes.
IMPORTANT: When operating on a/c power, the backlight and USB charge port will turn off while the
Weather Station searches for the WWVB signal, to avoid interference. Both features will return after
the 2-10 minute search which occurs during the late night or early morning hours.
Note: In case the Weather Station is not able to detect the WWVB-signal (disturbances, transmitting
distance, etc.); the time may be manually set.
Manual Signal Search: In normal mode, hold the RCC button until the reception icon appears to force a
search of the WWVB signal. The WWVB icon will flash during the search. If this icon disappears after
the 2-minute search, the radio time signal is not available at the moment.
Recommended distance to any interfering sources like computer monitors or TV sets is a minimum of
6 feet (2 meters).
Within ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened.
In extreme cases, please place the unit close to a window and/ or point its front or back towards the
Fort Collins, Colorado, transmitter.
During nighttime, the atmospheric disturbances are usually less severe and reception is possible in
most cases. A single daily reception is adequate to keep the accuracy deviation below 1 second.
Note: In case the Weather Station is not able to detect the WWVB-signal (disturbances, transmitting
distance, etc.), the time and date can be manually set (see “program menu”).

For example: you can use the USB charge cord to connect your cell phone to the USB charge port on
the back of the Weather Station and allow your phone to charge. The Weather Station must be operating
with a/c power in order to charge your device.
DO NOT try to charge the weather station by connecting a USB cable from the Weather Station to your
computer etc. This is an output port only.
Connect your existing USB charging cord for your external device
to the USB charging port on the back of the Weather Station to
begin to charge. Charging times will vary.
Note: Check that your device will charge with the USB cord it came
with. Many USB cords are for data transfer only, and cannot be
used for charging.
Output: 1A maximum current USB.
Do NOT overload USB port.
Note: This is a power output (charging) port only. This port will
not supply power to the Weather Station.
IMPORTANT: When operating on a/c power, to avoid interference, the backlight and USB charge port
will turn off while the Weather Station searches for the WWVB signal. The backlight and USB charge port
resume after a 2-10 minute search which occurs during the late night or early morning hours.

when operating on batteries only.
WEATHER FORECAST ICONS:
The Weather Station unit predicts weather condition for the next 12-hours based on the change of
atmospheric pressure. As weather conditions cannot be 100% correctly forecasted we cannot be
responsible for any loss caused by an incorrect forecast.
THIS STATION LEARNS!
Please allow 3-4 weeks for barometer calibration to generate an accurate forecast.
IMPORTANT: As the forecast station builds memory, it will compare the current average pressure to the
past forty day average pressure for increased accuracy. The longer the forecast station operates in one
location the more accurate the forecast icons will be.
The icons forecast the weather in terms of getting better or worse and not necessarily sunny or rainy as
each icon indicates. For example, if the current weather is cloudy and the rainy icon is displayed, it does
not mean that the product is faulty because it is not raining. It simply means that the air pressure has
dropped and the weather is expected to get worse but not necessarily rainy.
Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather forecasting
feature is estimated to have an accuracy level of about 75% due to the varying areas the Forecast Station
has been designed for use. In areas that experience sudden changes in weather (for example from sunny
to rain), the Forecast Station will be more accurate compared to use in areas where the weather is
stagnant most of the time (for example mostly sunny).
