SETTING UP:
Note:
This weather station receives only one outdoor sensor.

First, insert the batteries into the Temperature sensor. (see “Install and replace batteries in
the Temperature sensor“).
Immediately after and within 30 seconds, insert the batteries into Weather station (see “Install
and replace batteries in the Weather station”). Once the batteries are in place, all segments
of the LCD will light up briefly. Following the time as 12:00 and the "Weather girl" icon will be
displayed. If these are not displayed after 60 seconds, remove the batteries and wait for at
least 10 seconds before reinserting them.

After inserting the batteries, the Weather station will start receiving data from the sensor. The
outdoor temperature and the signal reception icon should then be displayed on the Weather
station. If this does not happen after 3 minutes, the batteries will need to be removed from both
units and reset from step 1.
In order to ensure sufficient 915 MHz transmission however, this should under good conditions
be a distance no more than 100 meters between the final position of the Weather Station and
the sensor (see notes on “Mounting” and “915 MHz Reception”).
INSTANT TRANSMISSION is the state-of-the-art new
wireless transmission technology, exclusively designed and
developed by LA CROSSE TECHNOLOGY. INSTANT
TRANSMISSION offers you an immediate update (every 4
seconds!) of all your outdoor data measured from the
sensors: follow your climatic variations in real-time!
Note:
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:
In the event of changing batteries in any of the units, all units need to be reset by following the setting
up procedures. This is because a random security code is assigned by the sensor at start-up and this
code must be received and stored by the Weather station in the first 3 minutes of power being supplied
to it.

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 Projection 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.
°F/°C TEMPERATURE UNIT 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.
flashing
The default temperature reading is set to °F (degree Fahrenheit).
To select °C (degree Celsius):
Note:
After setting up, readings for weather forecasts should be disregarded for the next 12-24 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. 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).

The “°C or F” will be flashing, use the + key to toggle between “°C” and “°F”.
Once the desired temperature unit has been chosen, confirm with the SET key and exit the
setting mode.
WEATHER FORECAST AND TENDENCY:
The weather forecast icons (Weather girl):
One of the 15 different weather icons (featured by Weather girl with different clothing) is displayed in
the centre of LCD, which indicates the different forecast weather conditions (Sunny, Sunny + Cloudy or
Cloudy + Rainy) due to change in air pressure level and the current outdoor temperature:
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), remove the batteries and re-
insert them after about 30 seconds. By doing this, the Weather station 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. Again,
disregard weather forecasts for the next 12 to 24 hours as this will allow time for operation at a
constant altitude.

THE WEATHER TENDENCY INDICATOR
Sunny
Working together with the weather icons are the weather tendency indicators (the upward and
downward arrow located near the Weather girl). 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.

Therefore, user may see how the weather has changed and is expected to change. For example, if the
indicator is pointing downwards together with cloudy icons, it means that the last noticeable change in
the weather was when it was sunny (the sunny icon only). Therefore, the next change in the weather
will be the cloudy icons since the indicator is pointing downwards.
Sunny +
Cloudy
Note:
Once the weather tendency indicator has registered a change in air pressure, it will remain
permanently visualized on the LCD.
When the tendency indicator is pointing to the right, it means that no pressure change has been
detected by the weather station from the beginning. Therefore, the coming weather condition is
expected to be more or less the same as the current condition.

915 MHz RECEPTION
The Weather station should receive the temperature data within 5 minutes after set-up. If the
temperature data is not received 5 minutes after setting up (not successfully continuously, the outdoor
display shows “- - -” ), please check the following points:

The distance of the Weather station or sensor should be at least 1.5 to 2 meters away from any
interfering sources such as computer monitors or TV sets.
Avoid positioning the Weather station onto or in the immediate proximity of metal window
frames.
Using other electrical products such as headphones or speakers operating on the same signal
frequency (915MHz) may prevent correct signal transmission and reception.
Neighbours using electrical devices operating on the 915MHz signal frequency can also cause
interference.

DISPLAY OF OUTDOOR TEMPERATURE READING:
The outdoor temperature is measured and displayed on the first section of the LCD.
Note:
When the 915MHz signal is received correctly, do not re-open the battery cover of either the 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.
The transmission range is about 100 m from the sensor to the Weather station (in open space).
However, this depends on the surrounding environment and interference levels. If no reception is
possible despite the observation of these factors, all system units have to be reset (see Setting up).
