(not included) into the Wireless Forecast Station (see Power the Wireless Forecast Station). The
Wireless Forecast Station will light up and show, indoor temperature, humidity and channel 1.
2. Insert 2 fresh AA batteries into the transmitter, observing the correct polarity (see Install Batteries in
the Outdoor Transmitter).
Note: The CH switch is set to Channel 1 by default. Confirm channel 1 is selected.
3. Keep the transmitter 5-10 feet from the Wireless Forecast Station for 15 minutes to establish a good
connection.
4. Within 3 minutes the station will beep and the outdoor temperature should be shown on the Wireless
Forecast Station. If the outdoor temperature does not show after 3 minutes remove power from the
transmitter and the Wireless Forecast Station for 60 seconds and start again from step 1.
5. For optimum 433 MHz transmission, the outdoor transmitter should be placed a distance of no more
than 200 feet (60 meters, open air) from the Wireless Forecast Station.
IMPORTANT: When operating on a/c power, to avoid interference, the backlight and USB charge port
will turn off for 2-10 minutes while the Wireless Forecast Station searches for the WWVB signal. Both
features will return after the 2-10 minute search.

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 Wireless Forecast Station. However, due to the nature of the Earth’s Ionosphere,
reception is very limited during daylight hours. The Wireless Forecast 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
The WWVB time 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 Wireless Forecast Station has received the WWVB signal.
No tower icon is shown. The Wireless Forecast Station was unable to receive a signal at this time.
Reposition the Wireless Forecast Station for better signal reception or try again at bedtime.
The Wireless 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, the backlight and USB charge port will turn off while the
Wireless Forecast 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 Wireless 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 Wireless 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”).

Weather Forecast Icons
The Wireless Forecast 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 Wireless Forecast Station builds memory, it will compare the current average
pressure to the past forty day average pressure for increased accuracy. The longer the Wireless 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 Wireless
Forecast Station has been designed for use. In areas that experience sudden changes in weather (for
example from sunny to rain), the Wireless Forecast Station will be more accurate compared to use in
areas where the weather is stagnant most of the time (for example mostly sunny).
