TO INSTALL AND RE LACE BATTERIES IN THE THERMO-HYGRO
TRANSMITTER
The outdoor thermo-hygro transmitter uses 2 x AAA, IEC LR3, 1.5V batteries.
To install and replace the batteries, please follow the steps below:
1. Remove the battery cover by pushing the battery cover upwards with
your thumb.
2. Insert the batteries, observing the correct polarity see battery
compartment marking).
3. Replace the battery cover on the unit.
TO INSTALL AND RE LACE BATTERIES IN THE WEATHER STATION
The weather station uses 2 x C, IEC LR14, 1.5V batteries. To install and replace the
batteries, please follow the steps below:
1. Insert finger or other solid object in
the space at the bottom center of
the battery compartment and lift up
to remove the cover.
2. Insert batteries observing the
correct polarity see marking).
3. Replace compartment cover.

35
Battery replacement
• Replace the batteries when the battery symbol of the weather station appears near the
weather icon.
• When the batteries of the transmitter are used up, the low battery icon appears above
the outdoor humidity display.
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 due to a random security code assigned by the transmitter
at start-up. This code must be received and stored by the weather station in the first 3
minutes of power being supplied to the transmitter.
SETTING U
1. First, insert the batteries in the transmitter see “To install and replace batteries in
the thermo-hygro transmitter” above).
2. Within 2 minutes of powering up the transmitter, insert the batteries in the weather
station see “To install and replace batteries in the weather station” above). Once
the batteries are in place, all segments of the LCD will light up briefly. Following the
indoor temperature/humidity and the time as 00:00 will be displayed. If this information
is not displayed on the 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 transmitter. The outdoor temperature and humidity data 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.
4. In order to ensure sufficient 868 MHz transmission however, the distance between the

36
weather station and the transmitter should not be more than 100 meters see notes on
“ositioning” and “868 MHz Reception”).
Note:
In the event of changing batteries of the units, ensure the batteries do not spring free
from the contacts. Always wait at least 1 minute after removing the batteries before
reinserting, otherwise start up and transmission problems may occur.
5. Once the outdoor data reception test period is completed, the DCF tower icon in the
clock display will start flashing in the upper left corner. This indicates that the clock has
detected that there is a radio signal present and is trying to receive it. When the time
code is received, the DCF tower becomes permanently lit and the time will be
displayed.
DCF RADIO CONTROLLED TIME
The time base for the radio controlled time is a Cesium Atomic Clock operated by the
Physikalisch Technische Bundesanstalt Braunschweig which has a time deviation of less
than one second in one million years. The time is coded and transmitted from Mainflingen
near Frankfurt via frequency signal DCF-77 77.5 kHz) and has a transmitting range of
approximately 1,500 km. Your radio-controlled weather station receives this signal and
converts it to show the precise time in summer or wintertime.
The quality of the reception depends greatly on the geographic location. In normal cases,
there should be no reception problems within a 1,500 km radius of Frankfurt.
DCF reception is done twice daily at 02:00 and 03:00 am. If the reception is not successful at
03:00 am, then the next reception takes place the next hour and so on until 06:00am, or until
the reception is successful. If the reception is not successful at 06:00 am, then the next
attempt will take place the next day at 02:00 am.

37
SET key
If the tower icon flashes, but does not set the time or the DCF tower does not appear at all,
then please take note of the following:
• Recommended distance to any interfering sources like computer monitors or TV sets is
a minimum of 1.5 - 2 meters.
• Within ferro-concrete rooms basements, superstructures), the received signal is
naturally weakened. In extreme cases, please place the unit close to a window and/ or
point its front or back towards the Frankfurt transmitter.
• During nighttime, the atmospheric disturbances are usually less severe and reception
is possible in most cases. A single daily reception is adequate to keep the accuracy
deviation below 1 second.

WEATHER FORECASTING ICONS:
The weather icons in the second section of LCD can be displayed in any of the following
combinations:
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.
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.
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 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 12-24 hours. 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.

47
WEATHER TENDENCY INDICATOR
The weather tendency indicators located on the left side of the weather icons) are working
together with 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.
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:
Once the weather tendency indicator has registered a change in air pressure, it will remain
permanently visualized on the LCD.
AIR RESSURE HISTORY (ELECTRONIC BAROMETER WITH BAROMETRIC
RESSURE TREND)
The right section of the second section of the LCD shows the air pressure history bar graph.
Air pressure trend over the
last 12 hours

The bar graph indicates the air pressure history trend over the last 12 hours in 7 intervals: 0h,
-3h, -6h, -9h and -12h. The “0h” represents the current full hour air pressure recording. The
columns represent the “hPa” 0, ±1, ±3, ±5) at specific time. The “0” in the middle of this scale
is equal to the current pressure and each change ±1, ±3, ±5) represents how high or low in
“hPa“ the past pressure was compared to the current pressure.
If the bars are rising it means that the weather is getting better due to the increase of air
pressure. If the bars go down, it means the air pressure has dropped and the weather is
expected to get worse from the present time “0h“.
Note:
• For accurate barometric pressure trends, the weather station should operate at the
same altitude for recordings i.e. it should not be moved from the ground to the second
floor of the house). When the unit is moved to a new location, discard readings for the
next 12 hours.
INDOOR TEM ERATURE/HUMIDITY DATA
The indoor temperature and humidity data are automatically updated and displayed on the
first section of the LCD.
