TO INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION
The Weather Station uses 3 x AA, IEC LR6, 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.
TO INSTALL AND REPLACE BATTERIES IN THE THERMO-HYGRO
TRANSMITTER
The Thermo-Hygro Transmitter uses 2 x AA, IEC, LR6, 1.5V batteries. To install
and replace the batteries, please follow the steps below:
1. Remove the cover.
2. Insert the batteries, observing the correct polarity (see marking).
3. Replace the battery cover.
Note:
In the event of changing batteries in any of the units, all units need to be reset by

20
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.
BATTERY CHANGE:
It is recommended to replace the batteries in all units on an annual basis to ensure optimum
accuracy of these units.
Please participate in the preservation of the environment. Return used batteries
to an authorized depot.
SETTING UP
WHEN ONE TRANSMITTER IS USED
1. First, insert the batteries in the transmitter (see “How to install and replace batteries in the
Termo-hygro outdoor transmitter” above).
2. Within 2 minutes of powering up the transmitter, insert the batteries in the Temperature
Station (see “How 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 and a short signal tone
will sound. Following the indoor temperature/humidity and the time as 0:00 will be displayed.
If these information are 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
Weather Station and the transmitter should not be more than 100 meters (see notes on
“Positioning” 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.
WHEN MORE THAN ONE TRANSMITTER IS USED
1. User shall remove all the batteries from the Weather Station and transmitters, and wait 60
seconds.
2. Insert the batteries in the first transmitter.
3. Within 2 minutes of powering up the first transmitter, insert the batteries in the Weather
Station. Once the batteries are in place, all segments of the LCD will light up briefly and a
short signal tine will sound. Following the indoor temperature/humidity and the time as 0:00
will be displayed. If these information are not displayed on the LCD after 60 seconds, remove
the batteries from both units and wait for at least 60 seconds before reinserting them.
4. The outdoor temperature and humidity data from the first transmitter (channel 1) should then
be displayed on the Weather Station. Also, the signal reception icon will be displayed. If this
does not happen after 2 minutes, the batteries will need to be removed from both units and
reset from step 1.
5. Insert the batteries in the second transmitter as soon as the outdoor temperature and
humidity readings from the first transmitter are displayed on the Weather Station.
Note : User shall insert the batteries into the second transmitter within 45 seconds after the
Weather Station displays the information of the first transmitter.
6. The outdoor temperature and humidity from the second transmitter and the "channel 2" icon
should then be displayed on the Weather Station. If this does not happen after 2 minutes, the
batteries will need to be removed from all the units and reset from step 1.

21
7. Insert the batteries in the third transmitter 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 transmitter will be displayed and the channel icon will shift back to "1" once the
third transmitter is successfully received. If this is not happen, user shall restart the setting up
from step 1.
Note : User shall insert the batteries into the third transmitter within 45 seconds after the
Weather Station displays the information of the first transmitter. Or immediately after
reception of the second transmitter is finished.
8. In order to ensure sufficient 868 MHz transmission however, the distance between the
Weather Station and the transmitter should not be more than 100 meters (see notes on
“Positioning” and “868 MHz Reception”).
IMPORTANT:
Transmission problems will arise if the setting for additional 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.
RESETTING
The Weather Station and the Thermo-hygro transmitter need to be reset when one of the following
conditions occur:
• Unsuccessful 868 MHz signal reception.
• Malfunction on the units.
• Batteries replacement.
For resetting, remove all batteries from the units. Wait at least for 1 minute before powering up the
Weather station again. Proceed from step 1 in “Setting Up”.
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
fre uency 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 uality of the reception depends greatly on the geographic location. In normal cases, there
should be no reception problems within a 1500km radius of Frankfurt.
DCF reception occurs 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.
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.
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 ade uate to keep the accuracy deviation
below 1 second.
