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.

INSTALL AND REPLACE BATTERIES IN THE THERMO-HYGRO 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:

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

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.

24

BATTERY CHANGE:

It is recommended to replace the batteries in all units on an annual basis to ensure optimum accuracy of these units.

SETTING UP

WHEN ONE TRANSMITTER IS USED

1. First, insert the batteries in the transmitter (see “How to install and replace batteries in the Thermo-hygro

2. Within 2 minutes of powering up the transmitter, insert the batteries in the Weather Station (see “How to install

Please participate in the preservation of the environment. Return used batteries to an authorized
depot.

outdoor transmitter” above).
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.

25

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.

26

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 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.

27

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 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
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 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 1500km radius of Frankfurt.

Once the outdoor data reception learning 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 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.

29

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.
