General Instructions
This radiocontrolled atomic clock is the most accurate timepiece in North America. it rewives a time
signal transmitted by the National Institute of Standards and Technology (NIST), which is regulated by 3
atomic clocks and deviates less than one second within 3,000 years. The NIST broadcasts time signal
(WWVB. SOkHz) continuously from Fort Collins. Colorado. This signal can be received anywhere in the
continental USA that long wave (AM) rarfio reception l possible with a portable radio. It is expected that
signal cover a distance of over 2,000 miles from the transmitter. The clock will receive the signal within the
broadcast range anywhere an AM signal can be received. Generally the signal cannot be received. In
massive metal and concrete structures unless near a window. in addition, some environmental effects may
affect the transmitting distance. (See Environmental Reception Effects)
For more information, please study the WWVB Web page of the NIST al :
http://www,boulder.nist.govltimetregl
Environmental Reception Effects

experience weather extremes such as rain. snow, direct sunlight, etc. This allows you to receive an
accurate outside temperature I humidity I rainfall reading and weather forecast.
Note: For more details on synchronization, please refer to “Wireless Fternote Temperature
Transmission."
Weather Forecast
The local weather forecast and weather tendency are predicted using the rate of change in atmospheric
pressure determined by a precisely calibrated pressure sensor. After turning the unit on for the first time, it
takes 24 hours for the weather forecasting data to be calculated for the first time, Alter 24 hours. the unit
calculates the weather for the next 6 hours. To ensure a reliable weather calculation, do not relocate the
unit during operation. Weather tendency is indicated by an up or down forecast arrow. (See table below.)
1. The up arrow teem-a.» indicates a significant increase in atmospheric pressure. This normally means
the weather is going to improve.
2, The down arrow ioon(=#')~ indicates a significant decrease in atmospheric pressure. This means the
weather is going to get worse,
