WWVB RADIO CONTROLLED TIME
The NIST radio station, WWVB, is located in Ft. Collins, Colorado 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 Forecast Station. However, due to the nature of the Earth’s
Ionosphere, reception is very limited during daylight hours. The Forecast Station will search for a signal
every night when reception is best. The WWVB radio station derives its signal from the NIST Forecast
Station 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
Forecast Station regulates the WWVB transmitter.
WWVB RECEPTION ICON with full signal strength will appear on screen in front of the date
when the reception of atomic time is successful.
The tower icon will show solid when the Forecast Station has received the WWVB signal.
No tower icon displayed. The Forecast Station was unable to receive a signal at this time.
Reposition the Forecast Station for better signal reception or try again at bedtime.
The Forecast 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, to avoid interference, the backlight and USB charge port
will turn off while the Forecast Station searches for the WWVB signal. The backlight and USB charge port
resume after a 2-10 minute search.
Note: In case the Forecast 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 Forecast Station is not able to detect the WWVB-signal (disturbances, transmitting
distance, etc.), the time and date can be manually set (see “program menu”).

USB CHARGE PORT:
The integrated USB charging port (on back) will charge devices when the Forecast Station is plugged into
a power outlet.
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.
Charge a device:
1. Connect your existing USB charging cord for your external device to the USB charging port on the
back of the Forecast Station 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.
2. Output: 1A maximum current USB.
3. Do NOT overload USB port.
Note: This is a power output port only. The Forecast Station cannot be powered via this port.
Note: Charging times will vary based on battery depletion and the individual device.
Note: Many devices may require more power to charge than provided by this Forecast Station.
IMPORTANT: When operating on a/c power, to avoid interference, the backlight and USB charge port
will turn off while the Forecast 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).
