INITIAL SET UP:
Adapter on the main unit with batteries or a/c adapter and set the time zone &
weather icon:
The Time Zone will flash EST. Press and release the UP or DOWN button to
select the Time Zone. Press and release the SET button.
The Weather Forecast Icons will flash. Press and release the UP or DOWN
button to select the forecast Icon that represents your current local weather.
Press and release the SET button to confirm.
The Temperature area will flash as the display searches for a signal from
the outdoor transmitter.
Insert fresh alkaline batteries into the transmitter, observing the correct
polarity Press the TX button to send a signal after the display is powered up.
Keep the transmitter 5-10 feet from the weather station.
Within 3 minutes the station will beep and the outdoor temperature should be
displayed on the Weather station. If the outdoor temperature is not displayed
after 3 minutes hold the SEARCH button on the main unit to search for
outdoor sensor. Then press the TX button again on the sensor to send
signal. If that doesn’t work, remove power from both units and start again
from the beginning.
To ensure sufficient 434 MHz transmission, the outdoor transmitter should be
placed a distance of no more than 200 feet (60 meters, open air) from the
Color Weather station.

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
atomic weather station. However, due to the nature o f the Earth’s Ionosphere,
reception is very limited during daylight hours. The atomic weather station will
search for a signal every night when reception is best. The WWVB radio station
derives its signal from the NIST atomic weather 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 atomic weather station regulates the WWVB
transmitter.
WWVB RECEPTION icon with full signal strength will appear on screen if the
reception of atomic time is successful. The atomic weather station will have a daily
synchronization at 02:03 and 03:03 everyday. Each reception cycle is minimum
2.5 minutes and maximum 10 minutes.
In normal mode, press the RCC button until the reception icon appears to enforce
searching of radio-controlled clock signal. If this icon disappears afterwards, radio
time signal is not available at the moment.
1
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 atomic color weather station is not able to detect the WWVBsignal (disturbances, transmitting distance, etc.), the time can be manually set
(please refer to notes TIME SET).
PROGRAM MENU:
TIME SET: The SET button moves through the program menu and the UP or
DOWN button change the values.

barometric pressure changes.
WEATHER FORECAST ICONS:
The unit predicts weather condition of the next 12 – 24 hours based on the change
of atmospheric pressure. The weather forecast is based on atmospheric pressure
change and is about 70-75% correct. As weather conditions cannot be 100%
correctly forecasted, we cannot be responsible for any loss caused by an incorrect
forecast.

allows the station to alternately display indoor temperature/humidity and outdoor
temperature/humidity every 10 seconds. The word AUTO will appear in the lower
right display when this feature is active. Press and release the AUTO button to turn
the feature off again.
BACKLIGHT:
A/C adapter: The backlight can be on continuously when operation with the 6-volt
a/c adapter.

only.
It is recommended to replace the batteries in all units every 12 months to ensure
optimum accuracy of this unit. A low battery icon will display next to the outdoor
temperature when the transmitter batteries are low and next to the indoor
temperature then the batteries in the weather station are low.
