ABOUT WWVB (Radio Controlled Time)
The NIST (National Institute of Standards and Technology—Time and Frequency Division) WWVB radio
station is located in Ft. Collins, Colorado, and transmits the exact time and date 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 Weather Station. However, due to the nature of the Earth’s Ionosphere, reception is very limited during
daylight hours. The weather 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
is continually measuring every second, of every day, to an accuracy of ten billionths of a second per 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. For more information on the atomic clock and WWVB please see the NIST website at
http://www.boulder.nist.gov/timefreq/stations/wwvb.htm.

QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.
1. Have the indoor weather station and remote temperature/humidity sensor 3 to 5 feet apart.
2. Batteries should be out of both the indoor weather station and remote temperature/humidity sensor
units for 10 minutes.
3. Place the batteries into the remote temperature/humidity sensor first then into the indoor weather
station.
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the indoor weather station and remote temperature/humidity sensor will start to talk to each other
and the display will show the indoor temperature/humidity, outdoor temperature/humidity, heat index and dew
point. If the indoor weather station does not display all information after the 15 minutes please retry the set up
as stated above. After all information has been displayed for 15 minutes you can place your sensors outdoors
and set your time.
Important Notes on Set-up and Operation
•The remote temperature/humidity sensor should be placed in a dry, shaded area.
•Fog and mist will not harm your remote temperature/humidity sensor but direct rain must be avoided.
•The remote temperature/humidity sensor has a range of 330 feet. Any walls that the signal will have to pass
through will reduce distance. An outdoor wall or window can have up to 30 feet of resistance and an interior
wall can have up to 20 feet of resistance. Your distance plus resistance should not exceed 330 ft. in a
straight line.
•The remote temperature/humidity sensor transmits a signal every minute. After the batteries have been
installed, the indoor weather station will search for the signal for a duration of 4 minutes. If there is no
temperature or humidity reading in the OUTDOOR LCD after 4 minutes, make sure the units are within
range of each other, or repeat the battery installation procedure.
•If a button is pressed before the indoor weather station receives the signal from the remote
temperature/humidity sensor, you will need to follow the battery installation procedure again.
To complete the set up of your new wireless weather station after the 15 minutes have passed please follow the
steps that follow in the Detailed Set-Up Guide.

This method requires you to do nothing, except wait for the signal to be received, and to select a
time zone. Reception usually takes approximately 10 minutes during optimal conditions. The best
conditions for reception is at night, between midnight and 6:00 am—when there is less atmospheric
interference. To keep your time as accurate as possible, the indoor weather station conducts a
WWVB search every night between these hours, and overrides any manually set time. The WWVB
tower icon (appearing in the TIME LCD) will flash when a signal-search is in progress and a signal
is being received, and will remain steady when the signal has been received. If the WWVB time has
not been received after 15 minutes of battery installation, you may manually set the time or leave the
time function alone (reception will occur regardless).
B. MANUAL TIME SETTING
Note: When in the 12-hour format “P.M.” will appear to the left of the hour in the time LCD
between the hours of noon and midnight.

I. WEATHER FORECAST
The weather forecasting feature is estimated to be 75% accurate and is for the next 12 to 24 hours. The
weather forecast is based solely upon the change of air pressure over time. The WS-9043U averages past
air-pressure readings to provide an accurate forecast—creating a necessity to disregard all weather
forecasting for 12-24 hours after the unit has been set-up, reset, or moved from one altitude to another
(i.e. from one floor of a building to another floor). In areas where the weather is not largely affected by
the change of air pressure, the sensitivity setting should be set to 1. In areas where the air pressure
changes more rapidly (such as coastal areas) the sensitivity setting should be set to 3.
A. WEATHER ICONS
There are 3 possible weather icons that will be displayed in the FORECAST LCD:
Sunny—indicates that the weather is expected to improve (not that the weather will be sunny).
Sun with Clouds—indicates that the weather is expected to be fair (not that the weather will be
sunny with clouds).
Clouds with Rain—indicates that the weather is expected to get worse (not that the weather will
be rainy).
These icons indicate the expected weather change in the next 12 to 24 hours. The icon does not
give an exact prediction of the weather, however it should be viewed as a generalization of the
expected weather change (for example a “sunny” icon indicates the weather is expected to
improve).
The weather icons change when the unit detects a change in air pressure. The icons change in
order, from “sunny” to “partly sunny” to “cloudy” or the reverse. It will not change from
