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 througho ut 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 lim ited 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, 6 31,7 7 0 vibra tio ns of a Cesium - 133 at om in a
vacuum. For more informa tion on the atomic clock and WWVB pl ease see the NIST website at
http://www.boulder.nist.gov/timefreq/stations/wwvb.htm

QUICK SET-UP GUIDE
Hint: Use good quality Al kalin e 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 temperatur e/humidity sensor units for 10

minutes.

3. Place the batteries into the remote temperature/humidity sensor first then into the indoor weathe r 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 displa y 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/humidit y 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 w all 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. A fter the batteries have been installed, the indoor

weather station will search for the signal for a durat ion of 4 minu tes. I f there is no tempera tur e or humid ity rea ding i n th e
OUTDOOR LCD after 4 minutes, make sure the units are within range of each other, or repeat the battery installation
procedure.

3

• If a button is pressed before the indoor weather station re ceive s the signal from the remote temperature/humidity senso r , 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.

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 rec e ived, 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).

FEATURES OF THE WS-9043U

)

I. WEATHER FORECAST

The weather forecasting feature is estimated to be 75% accurate and is for the next 12 to 24 hours. The weather fore cast
is based solely upon the change of air pressure over time. The WS-904 3U aver ages pa s t air- pr essur e rea dings to provi de
an accurate forecast—creating a necessity to disregard all weather forecasting for 12-24 hours after the unit has been set­up, reset, or moved from one altitude to another (i.e. from one fl oor of a buildi ng to a not her floor ). In areas where the
weather is not largely affected by the change of air pressure, the sensiti v it y setting shou ld be set to 1. In area s where the
air pressure changes more rapidly (such as coastal areas) the sensi tivity setting should be set to 3.

Heat Index

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 wh en 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 “sunny” directly to “rainy”,
although it is possible for the change t o occur quickly. If the symbols do not change then the weather has not
changed, or the change has been slow and gradual.

Other possible displays in the F ORECAST LCD are 2 weather tendency arrows, one that points up (on the lef t
side of the LCD) and one that points down (on the right side of the LC D). These arrows reflect current changes
in the air pressure. An arrow pointing up indicates that the air pressure is increasing and the weather is expected
to improve or remain good, an arrow pointing down indicates that the air pressure is decreasing and the weather
is expected to become worse or remain poor.

VII. ADDING REMOTE TEMPERATURE/HUMIDITY SENSORS (OPTIONAL)

The WS-9043U is able to receive signals from 3 different rem ote temperature/humidity sensors. The remote
temperature/humidity sensor model(s) that you choose will come with their own set of instructions—fol low these
instructions for a complete guide to setting up. Following are some brief instructions for the basic set-up of remote
temperature/humidity sensor units with the WS-9043U. These extra sensors can be purchased through the same deale r as
this unit, or by contacting La Crosse Technology directly. A TX4U will monitor temperature and humidity, a TX 6U will

10

monitor temperature only, a TX3U will monitor temperatu re and display the temperature on its LCD, and the TX3UP
will monitor the temperature via a probe for use in pools, spas, etc.

Note: When setting up multiple units it is important to remove the batteries from all existing units in operation, then to
insert batteries first into all the remote tempera ture sensor units. Wait until the first tra nsmitter reception is received by
the indoor weather station before inserting batter ies int o th e next transmitter and so forth. After all the transmitters
reception is received, install batteries into the indoor weather station. Transmission problems will arise if this is not done
correctly and if the total time for set-up exceeds 4 minutes.

A. SET-UP OF MULTIPLE UNITS

MOUNTING

Note: Before permanently mounting ensure that the indoor weather station is able to receive WWVB signals from the

desired location. Also, extreme and sudden changes in temperature will decrease the accuracy of the indoor weather
station, and changes in elevation will result with inaccurate weather forec asting for t he next 12 to 24 hour s. These
changes will require a 12 to 24 ho ur wait before obtaining reliable data. To achieve a true te mperature reading, avoid
mounting where direct sunlight can reach the remote temperature/humidity sensor or indoor weather station. While the
remote temperature/humidity sens or is weath er proof, avoid submersion in water or snow. We recommend that you
mount the remote temperature/humidi t y sensor on an outside Nor th-fa c i n g wall. The sen ding r ange is 330ft— obs tac le s
such as walls, concrete, and large metal objects can reduce the range. Place both units in their desired location, and wait
approximately 15 minutes before perma nent ly moun t in g to ensur e that the r e is proper reception. The indoor weather
station should display a temperature and hum idity in the OU TD O O R LCD within 4 minutes of setting up.

I. THE REMOTE TEMPERATURE/HUMIDITY SENSOR

1. It is necessary to remove the batteries from all units currently in operation.

2. Remove the battery covers to all remote temperature/humidity sensor units.

3. Place all remote temperature/humidity sensor units in a numeric sequential order.

4. In sequential order, install batteries (follow the same battery installation procedures seen in section I. A) of
the Detailed Set-Up Guide).

5. Install batteries into the indoor weather station.

6. Follow the Detailed Set-Up Guide for programming and o perating instructions.

B. VIEWING AND OPERATING WITH MULTIPLE REMOTE TEMPERATURE/HUMIDITY
SENSOR UNITS

1. To view the temperature, humidity, heat index and dew point of a different remote temperature sensor unit,
press and release the SNOOZE/CH button. A shift from one “boxed” number to the next should be observed
in the OUTDOOR LCD.

2. To view the Minimum/Maximum temperature, humidity, heat index and dew point: first select which
remote temperature/humidit y sensor to read data from (indicated by the “boxed” number), then press the

OUT button. To view the readings from different transmitters, follow IV. B. Viewing the Outdoor
Temperature/Humidity/Heat Index/ and Dew Records paragraph above.

4. To reset the Minimum/Maximum readings, select f irst which remote temperature/humidity sensor to read
data from. Press the OUT button to view the outdoor MIN/MAX records. Then follow the steps in IV. C.

The indoor weather station can be mounted in several ways:

• With the use of screws

• Using its foldout stand

A. MOUNTING WITH SCREWS

1) Fix a screw (not included) into the desired wall, leaving approximately

3/16 of an inch (5mm) extended from the wa ll.

2) Place the indoor weather station onto the screw using the hanging hole

on the backside.

3) Gently pull the indoor weather station down to lock the screw into place.

B. FOLDOUT TABLE STAND:

The foldout table stand leg is located on the backside.

1) Pull the stand out from the bottom center edge of the weather station,
below the battery compartment.

2) Once the foldout table stand is extended, place the weather station in an
appropriate location.

TROUBLESHOOTING
NOTE: For problems not solved, please contact La Crosse Technology.

Problem: No reception of WWVB time signal.
Solution: 1) Wait overnight for signal.

2) Be sure indoor weather station is at least 6 feet from any electrical devices, such as televisions, computers, or other
radio-controlled clocks.

3) Remove batteries for five minutes, reinsert and leave the unit alone overnight without pressing buttons.

4) If there are still problems, contact La Crosse Technology.

Problem: Hour is incorrect (minute and date are correct).
Solution: Be sure correct time zone and daylight saving time settings are selected.

Problem: The LCD is faint.
Solution: 1) Set the LCD contrast to a higher number.

2) Replace the batteries

Problem: No outdoor temperature/humidity is displayed.
Solution: 1) Remove all batteries, reinsert into remote temperature/humidity sensor first, then the indoor weather station.

2) Place the remote temperature/humidity sensor closer to the display.

3) Be sure all batteries are fresh.

4) Place the remote temperature/humidity sensor and indoor weather station in position so the straight-line signal is not
passing through more than two or three wall s.

Problem: Temperatures do not match if units are placed next to each other.
Solution: Each temperature/humidity sensor is manufactured to be accurate to within 2 degree plus or minus and under normal

conditions, so two sensors could be as much as 4 degrees different. However, the difference can be exaggerated further
because the sensors are designed for different working environments. The indoor temperature sensor is less responsive
to ambient air currents because of the shielding effect of the display's case. In addition, the case can act as a heat sink to
absorb and store heat from external sources (i.e. handling of the case or radiant heat). A lso, the much greater range of
the remote temperature/humidity sensor requires a different calibration curve than the indoor range. Error is usually
greater at the extreme ends of a range , making it harder to compare different ranges with different curves. Under non-

MAINTENANCE AND CARE INSTRUCTIONS

• Extreme temperatures, vibration, and shock should be avoided to pr eve n t dam age to the uni ts.

• Clean displays and units with a soft, damp cloth. Do not use solvents or scouring agents; they may mark the displays and

casings.

• Do not submerge in water.

• Immediately remove all low powered batteries to avoid leakage and damage.

• Opening the casings invalidates the warranty. Do not try to repair the unit. Contact La Crosse Technology for repairs.
