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  
QUICK SET-UP GUIDE  
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.  
1. Have the Wireless Weather Station and remote temperature sensor 3 to 5 feet apart.  
2. Batteries should be out of both units for 10 minutes.  
3. Place the batteries into the remote temperature sensor first then into the Wireless  
Weather Station.  
(All remote temperature sensors must be started before the Wireless Weather Station)  
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.  
In this time the Wireless Weather Station and remote temperature sensor will begin to  
communicate with each other and the display will show both the indoor temperature and the  
outdoor temperature. If the Wireless Weather Station does not display both temperatures after  
the 15 minutes please retry the set up as stated above. After both indoor and outdoor  
temperatures are displayed for 15 minutes you can place your remote temperature sensor  
outdoor and set your time.  
The remote temperature sensor should be placed in a dry, shaded area. The temperature  
sensor has a range of 330 feet. Keep in mind that the 330 feet is in open air with no  
obstructions and that radio waves DO NOT curve around objects. Actual transmission range will  
vary depending on what is in the path of the signal. Each obstruction (roof, walls, floors,  
ceilings, thick trees, etc.) will effectively cut signal range in half.  
Example: A Wireless Weather Station with a 330 feet range is mounted on an interior wall, so  
that the signal has to pass through one interior wall, one exterior wall, and across the 10 feet  
width of the room between the 2 walls. The first wall will reduce the range to 165 feet, and the  
second wall will reduce the range to 87 feet. Factoring in the 10 foot room, this leaves a  
maximum of 77 feet of remaining signal range.  
This allowance is typically enough for a frame wall with non-metallic siding; however certain  
materials can reduce range even further. Metal siding, stucco, and some types of glass can  
reduce signal range by as much as ¾ or more, compared to the ½ reduction typical of most  
obstructions. It is possible to receive a signal through these materials, however maximum range  
will be much less due to their tendency to absorb or reflect a much larger portion of the sensor’s  
signal.

To complete the set up of your Wireless Weather Station after the 15 minutes have passed  
please follow the steps that follow in the Detailed Set-Up Guide.  
DETAILED SET-UP GUIDE  
I.  
BATTERY INSTALLATION (When one temperature sensor is being used)  
1. First, insert the batteries to the temperature sensor (see “A. Remote Temperature  
Sensor” below).  
2. Within 30 seconds of powering up the sensor, insert the batteries to the Weather  
Station (see “B. Wireless Weather Station” below). Once the batteries are in place, all  
segments of the LCD will light up briefly. Following the indoor temperature, and the  
time as 12:00 will be displayed. If they are not shown in LCD after 60 seconds, remove  
the batteries and wait for at least 60 seconds before reinserting them. Once the indoor  
data is displayed user may proceed to the next step.  
3. After the batteries are inserted, the Weather Station will start receiving data signal  
from the sensor. The outdoor temperature should then be displayed on the Weather  
Station. If this does not happen after 2 minutes, the batteries will need to be removed  
from both units and reset from step 1 and the signal reception icon is no longer shown.  
A. REMOTE TEMPERATURE SENSOR  
1. Remove the mounting bracket. The bracket snaps on  
and off easily.  
Battery  
Cover  
2. Remove the battery cover, by sliding the cover down.  
3. Observing the correct polarity install 2 AA batteries. The  
batteries will fit tightly (to avoid start-up problems make  
sure they do not spring free).  
4. Replace the battery cover by sliding upwards. Be sure  
battery cover is on securely.  
B. WIRELESS WEATHER STATION  
1. Remove the battery cover. To do this, insert a solid object in the space provided  
at the lower-central position of the battery cover, then push up and pull out on the  
battery cover.  
2. Observe the correct polarity, and install 2 AA batteries.  
3. Replace the battery cover.

* When the signal is successfully received by the Weather Station, the icon will be  
switched on. (If not successful, the icon will not be shown in LCD) So the user can  
easily see whether the last reception was successful (icon on) or not (icon off). On the  
other hand, the short blinking of the icon shows that a reception is being done now.  
If the signal reception is not successful on the first frequency (915MHz) for 45 seconds, the  
frequency is changed to 920MHz and the learning is tried another 45 seconds. If still not  
successful the reception is tried for 45 seconds on 910MHz. This will also be done for re-  
synchronization.  
PROGRAM MODE  
Programming Note: If 30 seconds is allowed to pass, or the CH button is pressed  
during the programming mode, the unit will confirm/set the last information entered—  
the display will stop flashing and return to normal time-date readings. If you don’t leave  
the program mode during the programming of sections III through XII, you can  
advance to step 4 of the next program setting. If you do leave the program setting (or  
want to program a specific setting) follow each instructional step to program that  
setting.

TIME SETTING  
8
 
There are two methods by which the time and date can be set:  
A) Automatically via WWVB reception, or  
B) Manually.  
A. WWVB (Remote Control Time)  
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 condition 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 Wireless 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 10 minutes of battery installation, you  
may manually set the time or leave the time function alone (reception will occur regardless).  
After a successful reception, no more reception attempt would be made until the following day.  
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.  
1. Press and hold the SET button for 5 seconds.  
2. “LCD” will show in the time LCD and the number setting will flash.  
3. Press and release the SET button five times.  
4. The time will flash in the time LCD.  
5. Press and release the IN button to advance the hours.

areas have more pressure change than areas such as southern Arizona).  
The numbers correspond to the amount of air pressure change necessary to  
trigger a change in the forecast icon. Areas that tend to have more air  
pressure change would set the sensitivity to 3, while areas that experience  
lower than normal air pressure change would set the sensitivity to 1.  
1. Press and hold the SET button for 5 seconds.  
2. “LCD” will show in the time LCD and the number setting will flash.

FEATURES OF THE WS-9077U-IT  
WWVB Tower Icon (indicates time  
reception)  
Forecast icon  
Weather Tendency Arrow  
Satellite icon (indicates  
outdoor transmission)  
Remote Sensor Number  
(Up to 3 Total)  
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-9077U-IT 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.  
A. WEATHER ICONS  
There are 3 possible weather icons that will be displayed in the FORECAST  
LCD:  
11  
 
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 “sunny” directly to “rainy”, although it is  
possible for the change to occur quickly. If the symbols do not change then  
the weather has not changed, or the change has been slow and gradual.  
B. WEATHER TENDENCY ARROWS  
Other possible displays in the FORECAST LCD are 2 weather tendency  
arrows, one that points up and one that points down (on the right side of the  
LCD). 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.  
II. INDOOR TEMPERATURE  
The current indoor temperature is displayed in the INDOOR LCD.  
III. OUTDOOR TEMPERATURE  
The temperature received from the remote temperature sensor is viewed in the  
OUTDOOR LCD. When there is more than one remote temperature sensor unit in  
operation, a “boxed” number will appear to the right of the temperature. This indicates  
which remote temperature sensor unit (1, 2, or 3) is currently displaying its data in the  
OUTDOOR LCD. (This feature is explained in further detail in section VAdding  
Remote Temperature Sensors).  
IV. MINIMUM AND MAXIMUM TEMPERATURE RECORDS  
The WS-9077U-IT keeps a record of the MINIMUM and MAXIMUM temperature, and  
the time and date of their occurrence—for both the indoor and outdoor modes.  
A. VIEWING THE INDOOR TEMPERATURE RECORDS  
1. Press the IN button once. “MIN” appears above the indoor  
temperature and the LCD will flash, indicating that the minimum  
temperature and the time and date of occurrence of the indoor  
12  
 
temperature is displayed. The minimum record will display for 30  
seconds before returning to the normal display mode.  
2. Press the IN button again (once while “MIN” is still displayed, twice  
otherwise). “MAX” appears above the indoor temperature and the LCD  
will flash, indicating that the maximum temperature and the time and  
date of occurrence of the indoor temperature is displayed.  
3. While “MAX” is still displayed press the IN button again to return to the  
current data display. Or you can wait 30 seconds, during either the  
minimum or the maximum readings, and the unit will automatically  
return to current data readings.  
B. VIEWING THE OUTDOOR TEMPERATURE RECORDS  
1. Press the OUT button once. “MIN” appears above the outdoor  
temperature and the LCD will flash, indicating that the minimum  
temperature, and the time and date of occurrence are displayed. The  
minimum records will display for 30 seconds before returning to the  
normal display mode.  
2. Press the OUT button again (once while “MIN” is still displayed, twice  
otherwise). “MAX” appears above the outdoor temperature and the  
LCD will flash, indicating that the maximum temperature and the time  
and date of occurrence are displayed.  
3. While “MAX” is still displayed press the OUT button again to return to  
the current data display. Or you can wait 30 seconds, during either the  
minimum or the maximum readings, and the unit will automatically  
return to current data readings.  
C. RESETTING THE MIMIMUM AND MAXIMUM RECORDS  
1. All the Indoor records (minimum and maximum) will be reset after the  
IN button is pressed and held for 5 seconds.  
2. All the Outdoor records (minimum and maximum) will be reset after the  
OUT button is pressed and held for 5 seconds.  
V. ADDING REMOTE TEMPERATURE SENSORS (OPTIONAL)  
The WS-9077U-IT is able to receive signals from 2 additional temperature sensors.  
The following are instructions for the set-up of temperature sensor units with the WS-  
9077U-IT. These extra sensors can be purchased through the same dealer as this  
unit.  
13  
 
1. Remove all the batteries from the receiver and sensor(s) and wait 60 seconds.  
During these 60 seconds, press any button 20 times to discharge any excess  
power.  
2. Insert the batteries to the first temperature sensor.  
3. Within 30 seconds of powering up the first sensor, insert the batteries to the  
Weather Station. Once the batteries are in place, all segments of the LCD will  
light up briefly. Following the indoor temperature, time as 12:00, calendar, and  
weather icons will be displayed. If they are not shown in LCD after 60 seconds,  
remove the batteries and wait for at least 60 seconds before reinserting them.  
4. The outdoor temperature from the first sensor (channel 1) should then be  
displayed on the Weather station. If this does not happen and the signal  
reception icon is not shown, after 2 minutes, the batteries will need to be  
removed from both units and reset from step 1.  
5. Insert the batteries to the second sensor as soon as the outdoor temperature  
readings from the first sensor are displayed on the Weather station.  
NOTE: You must insert the batteries into the second sensor within 10  
seconds of reception of the first sensor.  
6. The outdoor temperature from the second sensor and the "channel 2" icon  
should then be displayed on the Weather Station. If this does not happen after 2  
minute, the batteries will need to be removed from all the units and reset from  
step 1.  
7. Insert the batteries to the third sensor as soon as the "channel 2" icon and  
outdoor data are displayed on the Weather Station. Then within 2 minutes, the  
channel 3 outdoor data from the third sensor will be displayed and the channel  
icon will shift back to "1" once the third sensor is successfully received. If this is  
not happen, user shall restart the setting up from step 1.  
NOTE: You must insert the batteries into the third sensor within 10  
seconds of reception of the second sensor.  
IMPORTANT: Transmission problems will arise if the setting for multiple  
sensors is not followed as described above. Should transmission problems  
occur, it is necessary to remove the batteries from all units and start again  
the set-up from step 1.  
VI. VIEWING AND OPERATING WITH MULTIPLE REMOTE TEMPERATURE  
SENSOR UNITS  
1. To view the temperature of a different remote temperature sensor unit,  
press and release the 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: first select which remote  
temperature sensor to read data from (indicated by the “boxed” number),  
then press the OUT button. Pressing this button once will display the  
minimum temperature, and the date and time the data was recorded.  
Pressing this button a second time (while “MIN” is still displayed, otherwise  
press the button twice) will display the same data for the maximum  
recordings.  
6. To reset the Minimum/Maximum readings, it is necessary to select which  
remote temperature sensor you wish to reset. Press and hold the OUT  
button for 5 seconds, the records for the selected remote temperature  
sensor unit will be reset.  
14  
 
MOUNTING  
Note: Before permanently mounting, ensure that the Wireless 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 Wireless Weather Station,  
and changes in elevation will result with inaccurate weather forecasting for the next 12  
to 24 hours. These changes will require a 12 to 24 hour wait before obtaining reliable  
data. To achieve a true temperature reading, avoid mounting where direct sunlight can  
reach the remote temperature sensor or Wireless Weather Station. While the remote  
temperature sensor is weather proof, avoid submersion in water or snow. We  
recommend that you mount the remote temperature sensor on an outside North-facing  
wall. The sending range is 330ft—obstacles 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 permanently mounting to ensure that there is proper  
reception. The Wireless Weather Station should display a temperature in the  
OUTDOOR LCD within 4 minutes of setting up.  
I. THE REMOTE TEMPERATURE SENSOR  
The remote temperature sensor can be mounted in two ways:  
with the use of screws, or  
using the adhesive tape.  
A. MOUNTING WITH SCREWS  
1) Remove the mounting bracket from the remote temperature  
sensor.  
2) Place the mounting bracket over the desired location.  
3) Through the three screw holes of the bracket, mark the  
mounting surface with a pencil.  
4) Screw mounting bracket onto the mounting surface. Ensure  
that the screws are flush with the bracket.  
5) Insert the remote temperature sensor into the bracket.  
B. MOUNTING WITH ADHESIVE TAPE  
1) With a nonabrasive solution, clean and dry the back of the  
mounting bracket and the mounting surface to ensure a  
secure hold. The mounting surface should be smooth and  
flat.  
2) Remove the protective strip from one side of the tape.  
3) Adhere the tape to the designated area on the back of the  
mounting bracket.  
4) Remove the protective strip from the other side of the tape.  
5) Position the remote temperature sensor in the desired  
location, ensuring that the Wireless Weather Station can  
receive the signal.  
Note: Mounting with adhesive tape is not recommended as a permanent mounting solution.  
Only use the adhesive tape during set-up process.  
II. THE WIRELESS WEATHER STATION  
15  
 
The Wireless Weather Station can be mounted in two ways:  
free standing or,  
wall mounting  
A. FREE STANDING  
To have the Wireless Weather Station free standing, simply  
unfold the stands on the back and set on a stable flat surface.  
B. WALL MOUNTING  
1) Ensure that the integrated stands are folded in.  
2) Fix a screw (not included) into the desired wall, leaving  
approximately 3/16 of an inch (5mm) extended from the wall.  
3) Place the Wireless Weather Station onto the screw using the  
hanging hole on the backside.  
4) Gently pull the Wireless Weather Station down to lock the  
screw into place.  
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 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 batteries  
Problem: No outdoor temperature is displayed.  
Solution: 1) Remove all batteries, reinsert into sender first, then display.  
2) Place remote sender closer to display.  
3) Be sure all batteries are fresh.  
4) Place Remote Control Sender and Weather Station in position so the straight-line  
signal is not passing through more than two or three walls.  
Problem: Temperatures do not match if units are placed next to each other.  
16  
 
Solution: Each temperature sensor is manufactured to be accurate to within 2ºF plus or minus  
and under normal conditions, so two sensors could be as much as 4ºF different.  
However, the difference can be exaggerated further because the sensors are  
designed for different working environments. The indoor 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). Also, the much greater range of the outdoor  
temperature 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-laboratory conditions, it is difficult to  
compensate for the above factors and obtain an accurate comparison.  
MAINTENANCE AND CARE INSTRUCTIONS  
Extreme temperatures, vibration, and shock should be avoided to prevent  
damage to the units.  
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.
