• Over 200 FT. wireless transmission range
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.
INSTALL BATTERIES OR A/C POWER ADAPTER INTO THE WEATHER
STATION:
A/C power adapter:
Plug enclosed 6-volt a/c power adapter into a wall outlet, then into the weather
station.
Batteries:
 Remove battery: Slide tab to the left and pull out to remove battery
cover.
 Install three fresh AAA alkaline batteries according to the polarity
markings.
 Do Not Mix Old and New Batteries
 Do Not Mix Alkaline, Standard, or Rechargeable Batteries
If the weather station does not display indoor temperature after 60 seconds,
remove adapter and batteries, and wait for at least 60 seconds before powering up
the weather station again.
INSTALL BATTERIES IN THE TRANSMITTER:
 Remove screws and the battery
cover from the back of the
transmitter with a small screwdriver.
 Insert two fresh AAA alkaline
batteries into the transmitter,
observing the correct polarity (see
marking inside battery
compartment).
 Keep transmitter 5-10 ft. from the
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 of 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.
