HOW TO INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION
The Weather Station uses 2 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.

HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER
The Temperature 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 batterycover on the unit.
Note:
In the event of changing batteries in anyof 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.

24
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

25
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 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

26
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 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 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 is not happen,
user shall restart the setting up from step 1.

27
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 Temperature transmitter need to be reset when one of the following conditions occur:
• Unsuccessful 868MHz 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
