Next, insert the batteries into the Thermo-hygro sensor and Rain sensor (optional -  
purchased separately) See “How to install and replace the batteries into the  
Thermo-hygro sensor“ and “How to install and replace the batteries into the  
Rain sensor (optional)” below.  
Then insert the batteries into the Weather Center (See “How to install and replace  
the batteries into the Weather Center” below). Once the batteries are installed, all  
segments of the LCD will light up briefly. It will then display the time as 12:00, the  
date as 1.1.09, the weather icons, and air pressure value. "- - -" will be shown for  
outdoor data.  
Afterwards, the Weather Center will start receiving data from the transmitter. The  
transmission reception icon will be blinking to indicate that the station is trying to get  
the thermo-hygro transmitter data. The outdoor temperature, humidity, wind data  
should then be displayed on the Weather Center. If this does not happen after 135  
seconds, the batteries will need to be removed from all units. You will have to start  
again from step 2.  
9.  
Radio interferences created by cordless phones, PC screens, radios or TV sets can  
in some cases entirely cut off radio communication. Please consider this when  
choosing standing or mounting locations.  
Note :  
After batteries are installed in the transmitter, install the batteries in the weather  
center to receive the signal from the transmitters as soon as possible. If the weather  
center is powered more than 5 hours after the transmitter is powered, the weather  
center will never receive signal successfully from the transmitters. In this case, you  
will need to reinstall the batteries from all the transmitters to redo set-up procedure.  
4.  
After batteries are installed, there will be synchronization between Weather Center  
and the transmitters. At this time, the signal reception icon will be blinking. When  
the signal is successfully received by the Weather Center, the icon will be  
switched on (If it is not successful, the icon will not be shown).  
The short blinking of the icon shows that a reception is in progress.  
5.  
6.  
The transmitter reception icon is now blinking again to indicate that the station is  
trying to get the rain sensor data. It will stop blinking once the rain sensor has been  
detected. If this does not happen after 135 seconds, you will need to start again from  
step 2.  
You should check the cable for correct connections and test all the components for  
correct functionality by manually turning the wind-gauge and by moving the wind-  
vane; tilting the optional rain sensor to hear the impact of the internal moving seesaw,  
etc. (See Positioning below).  
7.  
8.  
Time and date must be manually set (See Manual Setting below).  
After the Weather Center has been tested with regard to the above points and found  
fit, the initial set up of the weather station system is finished and the mounting of the  
system components can take place. It must be ensured however that all components  
work properly together at their chosen mounting or standing locations.  
Transmitter signal  
reception icon  
For example, if there appears to be problems with the 915 MHz radio transmission,  
they can mostly be overcome by slightly changing the mounting locations or turning  
the base station.  
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.  
Note:  
The radio communication between the receiver and the transmitters in the open field  
reaches distances of up to 330 feet/ 100 meters, provided there are no interfering  
obstacles such as buildings, trees, vehicles, high voltage lines, etc.

WEATHER FORECAST AND WEATHER TENDENCY  
WEATHER FORECASTING ICONS  
Weather icons in the third section of LCD can be displayed in any of the following  
combinations:  
Cloudy with sunny intervals  
Sunny  
Rainy  
Flashing  
For every sudden or significant change in the air pressure, the weather icons will update  
accordingly to represent the change in weather. If the icons do not change, then it means  
either the air pressure has not changed or the change has been too slow for the Weather  
station to register. However, if the icon displayed is a sun or raining cloud, there will be no  
change of icon if the weather gets any better (with sunny icon) or worse (with rainy icon)  
since the icons are already at their extremes.  
1.  
2.  
3.  
The threshold value will start flashing.  
Use the + or MIN/MAX key to select the value.  
Confirm with the SET key and enter the STORM ALARM ON/ OFF SETTING.  
The icons displayed forecasts the weather in terms of getting better or worse and not  
necessarily sunny or rainy as each icon indicates. For example, if the current weather is  
cloudy and the rainy icon is displayed, it does not mean that the product is faulty because  
it is not raining. It simply means that the air pressure has dropped and the weather is  
expected to get worse but not necessarily rainy.  
STORM ALARM ON/ OFF SETTING  
Note: the storm alarm ON/OFF setting is not available on this model. Skip and exit  
this setting by pressing the SET key.  
TO EXIT THE MANUAL SETTING MODE  
To exit the manual setting anytime during the manual setting modes, press the HISTORY  
key anytime or wait for the automatic timeout. The mode will return to the normal time  
display.  
Note:  
After setting up, readings for weather forecasts should be disregarded for the next 48-60  
hours. This will allow sufficient time for the Weather station to collect air pressure data at a  
constant altitude and therefore result in a more accurate forecast.  
Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather  
forecasting feature is estimated to have an accuracy level of about 75% due to the varying  
areas the Weather station has been designed for use. In areas that experience sudden  
changes in weather (for example from sunny to rain), the Weather station will be more  
accurate compared to use in areas where the weather is stagnant most of the time (for  
example mostly sunny).  
If the Weather station is moved to another location significantly higher or lower than its  
initial standing point (for example from the ground floor to the upper floors of a house),  
discard the weather forecast for the next 48-60 hours. By doing this, the Weather Station  
19  
20  
Download from Www.Somanuals.com. All Manuals Search And Download.  
will not mistake the new location as being a possible change in air-pressure when really it  
is due to the slight change of altitude.  
The vertical axis represents the air pressure changes in inHg (+0.12, +0.06, 0, -0.06, -0.12.  
The “0” represents the current air pressure). The newly measured pressure was compared  
to the previously recorded pressure reading. The pressure change is expressed by the  
difference between the current ("0h") and the past readings in division of ±2 hPa or ±0.06  
inHg. If the bars are rising it indicates that the weather is getting better due to an increase  
in air pressure. If the bars go down it indicates a drop of the air pressure and the weather  
is expected to get worse from the present time "0".  
WEATHER TENDENCY INDICATOR  
Working together with the weather icons is the weather tendency indicators (located on the  
left and right sides of the weather icons). When the indicator points upwards, it means that  
the air-pressure is increasing and the weather is expected to improve, but when indicator  
points downwards, the air-pressure is dropping and the weather is expected to become  
worse.  
At every full hour, the current air pressure is used as a basis for the display of a new graph  
bar. The existing graph is then moved one column to the left.  
Taking this into account, one can see how the weather has changed and is expected to  
change. For example, if the indicator is pointing downwards together with cloud and sun  
icons, then the last noticeable change in the weather was when it was sunny (the sun icon  
only). Therefore, the next change in the weather will be cloud with rain icons since the  
indicator is pointing downwards.  
Note:  
For accurate barometric pressure trend, the Weather Center should operate at the same  
altitude. For example, it should not be moved. Should the unit be moved, for instance from  
the ground to the second floor of the house, the readings for the next 48-60 hours shall be  
discarded..  
Note:  
Once the weather tendency indicator has registered a change in air pressure, it will remain  
permanently visualized on the LCD.  
WIND SPEED MEASUREMENT  
In normal display mode, the second section of the LCD shows the following wind data.  
Wind chill in F or C  
Wind Speed in km/h, mph or m/s  
AIR PRESSURE HISTORY (ELECTRONIC BAROMETER WITH  
BAROMETRIC PRESSURE TREND)  
The bottom section of the LCD also shows the relative air pressure value and the air  
pressure history.  
Gust in km/h, mph or m/s (displayed when in Mode 2, by pressing the SET key  
shortly)  
Wind speed or Gust will

Wind chill  
The bar graph of the electronic barometer shows the air pressure history of the past 12  
hours in five 3-hour steps.  
Air pressure  
changes in hPa  
Air pressure  
changes in inHg  
The horizontal axis represents the last 12 hours air pressure recording (-12, -9, -6, -3 and  
0 hour). The bars are plotted at each of the 5 steps and give the trend over the recorded  
period. The scale on the right compares the result. The "0" in the middle of this scale  
determines the current air pressure.

VIEWING THE HISTORY DATA  
The weather station can store up to 140 sets of weather data which are recorded  
automatically at 3-hour intervals after the weather station is powered up, at the nearest  
time of 0:00, 03:00, 06:00, 09:00, 12:00, 15:00, 18:00 and 21:00. For instance, if user has  
manually set the time as 14:52 after installing batteries, the first history record will be  
made at the coming 15:00 automatically. Then the second record will be on 18:00 and so  
on.  
Each weather record includes the Wind direction, Wind speed/ gust, Wind chill  
temperature, wind speed/gust, dew point, Outdoor temp and humidity, relative pressure,  
24-hour rainfall and total rainfall, pressure history and weather tendency. Also, the time  
and date of recording will be displayed.

Note:  
In order to acquire the correct time of recording of the history records, you shall manually  
set the current time as soon as possible after installing batteries to the weather station.  
Afterwards, you should avoid changing the pre-set time as it will also alter the recorded  
"time of recording" of each history record, which may lead to confusion.  
Note:  
The stored history records will not be retained after battery change or whenever  
battery is removed.

OUTDOOR TRANSMITTER 915 MHz RECEPTION CHECK  
POSITIONING:  
The outdoor temperature, humidity, wind data are transmitted from thermo-hygro  
transmitter every 4.5 seconds; the rainfall data are transmitted from the rain sensor  
(optional) every 6.25 seconds. The receiver will be synchronized to the thermo-hygro  
transmitter and rain sensor (optional) then. The transmission range (up to about 330 feet  
/100 meters in open air) of the thermo-hygro transmitter/ rain sensor may be affected by  
the ambient temperature. At cold temperatures, the transmitting distance may be  
decreased. Please keep this in mind when placing the transmitter and the rain sensor.  
Prior to permanently mounting any of the units, please ensure the following points are  
considered:  
Cable lengths of the units meet with your distance requirements at the point of fixing  
Signals from the sensors can be received by the base station at points of mounting  
La Crosse Technology Sensor Extension Cable  
You can purchase a La Crosse Technology Extension Cable if you require additional  
length to properly mount your sensor. The extension cable is 32 feet in length and comes  
with the appropriate connecter attached. Please visit your local retailer or  
other retailers.  
If (1) the outdoor data is not being received within first several minutes after setting up; (2)  
the outdoor display always shows “- - -“ on the outdoor display; or (3) the reception icon of  
thermo-hygro transmitter (Mode 1) and rain sensor (optional) (Mode 2) is not displayed on  
the display, check the following things:  
Using phone cables or connections may damage your sensors because phone cables and  
connections have more resistance than the La Crosse Technology extension cable. Phone  
cables or connections are not recommended for use.  
1.  
The distance of the Weather Station or transmitter/ rain sensor should be at least 5  
to 6.5 feet (1.5 to 2 meters) away from any interfering sources such as computer  
monitors or TV sets.  
2.  
3.  
Avoid positioning the Weather Center onto or in the immediate proximity of metal  
doors or window frames.  
Using other electrical products such as headphones or speakers operating on the  
same signal frequency (915 MHz) may prevent correct signal transmission and  
reception.  
Note: Using extension cables will shorten battery life.  
Warning: Never cut, splice, shorten or modify your sensor cables or extension cables.  
Doing so may damage your sensors and will void your warranty.  
The Weather Station  
The Weather Station has been designed to be hung onto wall or free standing with the two  
kinds of foldout stand.  
4.  
Neighbors using electrical devices operating on the 915 MHz signal frequency can  
also cause interference.  
Note:  
When the 915 MHz signal is received, do not re-open the battery compartment cover of  
either the transmitter/ rain sensor or Weather station, as the batteries may spring free from  
the contacts and force a false reset. Should this happen accidentally then reset all units  
(see Setting up above) otherwise transmission problems may occur.  
During normal operation, after the outdoor display shows "- - -", the weather station will  
change to receive the outdoor data every 15 minutes, until the data is read. Then the  
reception period for thermo-hygro transmitter will return to 4.5 seconds (6.25 seconds for  
rain sensor - optional).  
To wall mount  
Choose a sheltered place. Avoid direct rain and sunshine.  
Before wall mounting, please check that the outdoor temperature and  
humidity values can be received from the desired locations. To wall  
mount:  
1.  
Fix a screw (not supplied) into the desired wall, leaving the  
head extended out the by about 5mm.  
2.  
Hang the station onto the screw. Remember to ensure that it  
locks into place before releasing.  
If no reception is possible despite the observation of these factors, all system units have to  
be reset (see Setting up).

Main Unit  
Wall Bracket  
Horizontal panel  
An ideal mounting place for the thermo-hygro sensor would be the outer wall beneath the  
extension of a roof, as this will protect the sensor from direct sunlight and other extreme  
weather conditions.  
First, check that the wind-cups can rotate freely before fixing the unit. For correct and  
accurate readings, it is important to mount the sensor with the cups on the bottom. The  
wind sensor should now be mounted using the screw or cable tie provided onto a solid  
wall/ panel mast or mast to allow the wind to travel around the sensor unhindered from all  
directions (ideal mast size should be from diameter 0.62” to 1.29” (16mm to 33mm). Do  
not over tighten.  
Once the wind sensor is fixed onto the mast, connect the cable to the corresponding  
thermo-hygro sensor socket so that operating power supply can be received and data can  
be transmitted to the base station. Secure cord from blowing. Do not use staples. Using  
PVC pipe or metal as a mast may cause static. Wood is recommended.  
To wall mount, use the 2 screws to affix the wall bracket to the desired wall, plug in the  
thermo-hygro sensor to the bracket and secure both parts by the use of the supplied screw  
and ensure that the cable from the wind sensor is correctly plugged in otherwise data  
transmission errors could occur.  
The Rain Sensor (optional)

For best results, the rain sensor should be securely mounted onto a horizontal surface  
about 39.37” (1 meter) above the ground (or higher) and in an open area away from trees  
or other coverings where rainfall may be reduced causing inaccurate readings.
