HOW TO INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION
The Weather station uses 3 x AA, IEC LR6, 1.5V batteries. When batteries will need to
be replaced, the low battery icon will appear on the LCD. 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.
HOW TO INSTALL AND REPLACE BATTERIES IN THE THERMO-HYGRO OUTDOOR
TRANSMITTER
The Thermo-hygro transmitter uses 2 x AA, IEC LR6, 1.5V battery. To install and replace
the batteries, please follow the steps below:
1. Remove the battery compartment cover.
2. Insert the batteries, observing the correct polarity (see marking).
3. Replace the battery compartment cover on the unit.
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
transmitter 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

34
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
authorised 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”).

35
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 tone will sound.
Following the indoor temperature/humidity and the time as 0:00 will be displayed. If this information is 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.
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
does 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

36
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.
